+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+ 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+\f
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+\f
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+\f
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+\f
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+\f
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation; either version 2 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program; if not, write to the Free Software
+ Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) year name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+ <signature of Ty Coon>, 1 April 1989
+ Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+The TAPR Open Hardware License
+Version 1.0 (May 25, 2007)
+Copyright 2007 TAPR – http://www.tapr.org/OHL
+
+PREAMBLE
+
+Open Hardware is a thing - a physical artifact, either electrical or
+mechanical - whose design information is available to, and usable by,
+the public in a way that allows anyone to make, modify, distribute, and
+use that thing. In this preface, design information is called
+"documentation" and things created from it are called "products."
+
+The TAPR Open Hardware License ("OHL") agreement provides a legal
+framework for Open Hardware projects. It may be used for any kind of
+product, be it a hammer or a computer motherboard, and is TAPR's
+contribution to the community; anyone may use the OHL for their Open
+Hardware project.
+
+Like the GNU General Public License, the OHL is designed to guarantee
+your freedom to share and to create. It forbids anyone who receives
+rights under the OHL to deny any other licensee those same rights to
+copy, modify, and distribute documentation, and to make, use and
+distribute products based on that documentation.
+
+Unlike the GPL, the OHL is not primarily a copyright license. While
+copyright protects documentation from unauthorized copying, modification,
+and distribution, it has little to do with your right to make, distribute,
+or use a product based on that documentation. For better or worse, patents
+play a significant role in those activities. Although it does not prohibit
+anyone from patenting inventions embodied in an Open Hardware design, and
+of course cannot prevent a third party from enforcing their patent rights,
+those who benefit from an OHL design may not bring lawsuits claiming that
+design infringes their patents or other intellectual property.
+
+The OHL addresses unique issues involved in the creation of tangible,
+physical things, but does not cover software, firmware, or code loaded
+into programmable devices. A copyright-oriented license such as the GPL
+better suits these creations.
+
+How can you use the OHL, or a design based upon it? While the terms and
+conditions below take precedence over this preamble, here is a summary:
+
+* You may modify the documentation and make products based upon it.
+
+* You may use products for any legal purpose without limitation.
+
+* You may distribute unmodified documentation, but you must include the
+complete package as you received it.
+
+* You may distribute products you make to third parties, if you either
+include the documentation on which the product is based, or make it
+available without charge for at least three years to anyone who requests
+it.
+
+* You may distribute modified documentation or products based on it, if
+you:
+ * License your modifications under the OHL.
+ * Include those modifications, following the requirements stated
+ below.
+ * Attempt to send the modified documentation by email to any of the
+ developers who have provided their email address. This is a good
+ faith obligation – if the email fails, you need do nothing more
+ and may go on with your distribution.
+
+* If you create a design that you want to license under the OHL, you
+should:
+ * Include this document in a file named LICENSE (with the appropriate
+ extension) that is included in the documentation package.
+ * If the file format allows, include a notice like “Licensed under
+ the TAPR Open Hardware License (www.tapr.org/OHL)” in each
+ documentation file. While not required, you should also include
+ this notice on printed circuit board artwork and the product
+ itself; if space is limited the notice can be shortened or
+ abbreviated.
+ * Include a copyright notice in each file and on printed circuit
+ board artwork.
+ * If you wish to be notified of modifications that others may make,
+ include your email address in a file named “CONTRIB.TXT” or
+ something similar.
+
+* Any time the OHL requires you to make documentation available to
+others, you must include all the materials you received from the
+upstream licensors. In addition, if you have modified the
+documentation:
+ * You must identify the modifications in a text file (preferably
+ named "CHANGES.TXT") that you include with the documentation.
+ That file must also include a statement like "These modifications
+ are licensed under the TAPR Open Hardware License."
+ * You must include any new files you created, including any
+ manufacturing files (such as Gerber files) you create in the
+ course of making products.
+ * You must include both "before" and "after" versions of all files
+ you modified.
+ * You may include files in proprietary formats, but you must also
+ include open format versions (such as Gerber, ASCII, Postscript,
+ or PDF) if your tools can create them.
+
+TERMS AND CONDITIONS
+
+1. Introduction
+1.1 This Agreement governs how you may use, copy, modify, and
+distribute Documentation, and how you may make, have made, and
+distribute Products based on that Documentation. As used in this
+Agreement, to "distribute" Documentation means to directly or indirectly
+make copies available to a third party, and to "distribute" Products
+means to directly or indirectly give, loan, sell or otherwise transfer
+them to a third party.
+
+1.2 "Documentation" includes:
+ (a) schematic diagrams;
+ (b) circuit or circuit board layouts, including Gerber and other
+ data files used for manufacture;
+ (c) mechanical drawings, including CAD, CAM, and other data files
+ used for manufacture;
+ (d) flow charts and descriptive text; and
+ (e) other explanatory material.
+Documentation may be in any tangible or intangible form of expression,
+including but not limited to computer files in open or proprietary
+formats and representations on paper, film, or other media.
+
+1.3 "Products" include:
+ (a) circuit boards, mechanical assemblies, and other physical parts
+ and components;
+ (b) assembled or partially assembled units (including components
+ and subassemblies); and
+ (c) parts and components combined into kits intended for assembly
+ by others;
+which are based in whole or in part on the Documentation.
+
+1.4 This Agreement applies to any Documentation which contains a
+notice stating it is subject to the TAPR Open Hardware License, and to
+all Products based in whole or in part on that Documentation. If
+Documentation is distributed in an archive (such as a "zip" file) which
+includes this document, all files in that archive are subject to this
+Agreement unless they are specifically excluded. Each person who
+contributes content to the Documentation is referred to in this
+Agreement as a "Licensor."
+
+1.5 By (a) using, copying, modifying, or distributing the
+Documentation, or (b) making or having Products made or distributing
+them, you accept this Agreement, agree to comply with its terms, and
+become a "Licensee." Any activity inconsistent with this Agreement will
+automatically terminate your rights under it (including the immunities
+from suit granted in Section 2), but the rights of others who have
+received Documentation, or have obtained Products, directly or
+indirectly from you will not be affected so long as they fully comply
+with it themselves.
+
+1.6 This Agreement does not apply to software, firmware, or code
+loaded into programmable devices which may be used in conjunction with
+Documentation or Products. Such software is subject to the license
+terms established by its copyright holder(s).
+
+2. Patents
+2.1 Each Licensor grants you, every other Licensee, and every
+possessor or user of Products a perpetual, worldwide, and royalty-free
+immunity from suit under any patent, patent application, or other
+intellectual property right which he or she controls, to the extent
+necessary to make, have made, possess, use, and distribute Products.
+This immunity does not extend to infringement arising from modifications
+subsequently made by others.
+
+2.2 If you make or have Products made, or distribute Documentation
+that you have modified, you grant every Licensor, every other Licensee,
+and every possessor or user of Products a perpetual, worldwide, and
+royalty-free immunity from suit under any patent, patent application, or
+other intellectual property right which you control, to the extent
+necessary to make, have made, possess, use, and distribute Products.
+This immunity does not extend to infringement arising from modifications
+subsequently made by others.
+
+2.3 To avoid doubt, providing Documentation to a third party for the
+sole purpose of having that party make Products on your behalf is not
+considered "distribution," and a third party's act of making Products
+solely on your behalf does not cause that party to grant the immunity
+described in the preceding paragraph.
+
+2.4 These grants of immunity are a material part of this Agreement,
+and form a portion of the consideration given by each party to the
+other. If any court judgment or legal agreement prevents you from
+granting the immunity required by this Section, your rights under this
+Agreement will terminate and you may no longer use, copy, modify or
+distribute the Documentation, or make, have made, or distribute
+Products.
+
+3. Modifications
+You may modify the Documentation, and those modifications will become
+part of the Documentation. They are subject to this Agreement, as are
+Products based in whole or in part on them. If you distribute the
+modified Documentation, or Products based in whole or in part upon it,
+you must email the modified Documentation in a form compliant with
+Section 4 to each Licensor who has provided an email address with the
+Documentation. Attempting to send the email completes your obligations
+under this Section and you need take no further action if any address
+fails.
+
+4. Distributing Documentation
+4.1 You may distribute unmodified copies of the Documentation in its
+entirety in any medium, provided that you retain all copyright and other
+notices (including references to this Agreement) included by each
+Licensor, and include an unaltered copy of this Agreement.
+4.2 You may distribute modified copies of the Documentation if you
+comply with all the requirements of the preceding paragraph and:
+ (a) include a prominent notice in an ASCII or other open format
+ file identifying those elements of the Documentation that you
+ changed, and stating that the modifications are licensed under
+ the terms of this Agreement;
+ (b) include all new documentation files that you create, as well as
+ both the original and modified versions of each file you change
+ (files may be in your development tool's native file format,
+ but if reasonably possible, you must also include open format,
+ such as Gerber, ASCII, Postscript, or PDF, versions);
+ (c) do not change the terms of this Agreement with respect to
+ subsequent licensees; and
+ (d) if you make or have Products made, include in the Documentation
+ all elements reasonably required to permit others to make
+ Products, including Gerber, CAD/CAM and other files used for
+ manufacture.
+
+5. Making Products
+5.1 You may use the Documentation to make or have Products made,
+provided that each Product retains any notices included by the Licensor
+(including, but not limited to, copyright notices on circuit boards).
+5.2 You may distribute Products you make or have made, provided that
+you include with each unit a copy of the Documentation in a form
+consistent with Section 4. Alternatively, you may include either (i) an
+offer valid for at least three years to provide that Documentation, at
+no charge other than the reasonable cost of media and postage, to any
+person who requests it; or (ii) a URL where that Documentation may be
+downloaded, available for at least three years after you last distribute
+the Product.
+
+6. NEW LICENSE VERSIONS
+TAPR may publish updated versions of the OHL which retain the same
+general provisions as the present version, but differ in detail to
+address new problems or concerns, and carry a distinguishing version
+number. If the Documentation specifies a version number which applies
+to it and "any later version", you may choose either that version or any
+later version published by TAPR. If the Documentation does not specify
+a version number, you may choose any version ever published by TAPR.
+TAPR owns the copyright to the OHL, but grants permission to any person
+to copy, distribute, and use it in unmodified form.
+
+7. WARRANTY AND LIABILITY LIMITATIONS
+7.1 THE DOCUMENTATION IS PROVIDED ON AN "AS-IS" BASIS WITHOUT
+WARRANTY OF ANY KIND, TO THE EXTENT PERMITTED BY APPLICABLE LAW. ALL
+WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO ANY
+WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND
+TITLE, ARE HEREBY EXPRESSLY DISCLAIMED.
+7.2 IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW WILL ANY LICENSOR
+BE LIABLE TO YOU OR ANY THIRD PARTY FOR ANY DIRECT, INDIRECT,
+INCIDENTAL, CONSEQUENTIAL, PUNITIVE, OR EXEMPLARY DAMAGES ARISING OUT OF
+THE USE OF, OR INABILITY TO USE, THE DOCUMENTATION OR PRODUCTS,
+INCLUDING BUT NOT LIMITED TO CLAIMS OF INTELLECTUAL PROPERTY
+INFRINGEMENT OR LOSS OF DATA, EVEN IF THAT PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+7.3 You agree that the foregoing limitations are reasonable due to
+the non-financial nature of the transaction represented by this
+Agreement, and acknowledge that were it not for these limitations, the
+Licensor(s) would not be willing to make the Documentation available to
+you.
+7.4 You agree to defend, indemnify, and hold each Licensor harmless
+from any claim brought by a third party alleging any defect in the
+design, manufacture, or operation of any Product which you make, have
+made, or distribute pursuant to this Agreement.

+
+stty is a WRT54GL OpenWRT binary utility some one had compiled on the web, used
+for setting serial port speeds
+
+wispcar.asm is the original code as per the blog post: http://www.rowetel.com/blog/?p=68
+
+wispcarb.asm has a mod to the watchdog timer to stay off, used for battery testing

+
+Project Plan
+------------
+
+[ ] WP100 Documentation
+ [ ] Create SVN repository
+ [ ] Draw schematic
+ [ ] Write Test Report
+ + Discuss tests performed
+ + how to repeat them
+ + results
+ [ ] Software
+ [ ] Write Design Notes
+ + explain various sections of design
+ + discuss trade offs
+
+[ ] WP200 Prototype Development
+ [ ] Breadboard Prototype
+ [X] PIC with RS232
+ [X] Current sensor
+ + high-side op-amp differential amp
+ [X] Power Switch
+ + used to switch power to AP
+ + controlled by watchdog and sleep function
+ [ ] Linear Regulator
+ [X] Watchdog software
+ [X] Sleep software
+ [ ] Construct Soldered Prototype
+ [ ] Install in Solar powered AP (Rowetel)
+
+[ ] WP300 Testing
+ [ ] Test 1: false watchdog firing
+ + test_watchdog.tcl Exepct script
+ + sends 'w' every sec, look for false WD fire
+ + results: after approx 40 hrs, 91,000 seconds, no false firing
+
+ [ ] Test to determine watchdog doesn't fire by mistake
+ + leave running for 1 week
+ + stable power & router
+ + ensure watchdog doesn't fire by mistake
+ [ ] Dirty power test
+ + work out a way to simulate a poor power supply
+ + for example put power supply in series with transformer
+ secondary, then modulate primary with pulses
+ + this will give big spikes on power line
+ + make sure PIC never hangs
+ [ ] Brown out test
+ + vary Vbat from 30V down to 2V 10 times
+ + make sure PIC does not hang
+
+Specs:
+-----
+
+1/ Measures Vbat and Ibat.
+
+ Vbat between 5 and 60V
+ Ibat between 0 and 5A
+
+ Measures Vbat and Ibat and reports every 1 sec to Host.
+
+2/ Watchdog
+
+ Fires if no RS232 rx for TBD1 secs from host
+ Power is shut off for 5 seconds then reapplied
+
+3/ Sleep
+
+ Send "sleepXXXX" to put power supply to sleep for XXXX seconds
+
+4/ Current consumption (estimated)
+
+ Vbat = 30V I=2mA
+ Vbat = 5V I=2mA
+
+ Note: we need to work out a way to get 60V operation, 78L05
+ regulator can't go above 35V.

+Yahel Ben-David
+
+Notes
+-----
+
+1/ IRF9640 FET was selected largely at random. At 19A max it may be
+overkill, a cheaper FET may be more suitable.
+
+2/ The RS232 polarity may need to change when directly connected to a
+router without level conversion, see reference docs for RS232 software
+UART code in wispcar.asm. I used a MAX232 type chip for interfacing
+the RS232 tx & rx to a PC's serial port for testing.
+
+Gotchas
+-------
+
+1/ On the PIC12F510 we can only use 'call' to call an address in the
+first 256 bytes, so put all funcs at the start of the program, main at
+the end.
+
+2/ If the RS232 characters have occasional errors, the internal clock
+oscillator may need tweaking. You can check the baud rate of the
+RS232 signals using an oscilloscope, at 4800 baud the bit period
+should be 208us. See PIC data sheet for information on adjusting the
+internal oscillator.
+
+3/ The Vce(max) rating of Q2 is 35V, and Vgs(max) of Q1 +/- 20V. As
+R1/R2 form a voltage divider I think this sets the maximum Vbat at 35V
+for the current version, i.e. Q1 will pop first (as Vgs will hit 20V
+when Vbat=40V). Need higher Vce Q2 or change circuit to limit
+Vgs(max). Need to make sure sufficient Vgs to switch on Q1 at low
+Vbat. Maybe two versions with different R1/R2?
+
+4/ Current Sensor resistor values. When building the first soldered
+prototype I found that residual flux messed up the 10M R11 feedback
+resistor. Scraping flux away and cleaning with solvent brought the
+resistance back up again. This could be a problem with home
+construction, and possibly humid environments. Perhaps we should
+scale resistors down to say 100k/10k voltage dividers, 1M R11?
+
+5/ When building the first soldered prototype I found that the
+position of the ground wires carrying high current caused the current
+sensor to stop working (stuck at 0V). U2 GND and the GND of R7, R9,
+R10 where at different places along the GND track carrying 0.5A. This
+caused a voltage drop of about 5mV between the two GNDs. I moved the
+ground connection (made the GND in GND out points close to each other
+so 0.5A was only flowing thru a short section of track) and the
+current sensor started working again. This suggests a carefully laid
+out PCB is a good idea.
+
+6/ The voltage on pins 2 & 3 of U2 (+/i op-amp input) should be within
+10 mV of each other with U2 unplugged. A greater difference indicates
+one of the resistor values is wrong.

+ + malformed RS323 could cause a hang
+ + maybe better to just look at h/l transition or something?
+ + sep pic for sleep function?
+ + solution: integrate 1 sec delay with RS232 rx
+[ ] Limitations
+ + need to send full command before 1 second delay?
+ + like send command immediately after ADC data

+
+[ ] automatic thrash tests (repeat each one for hours/days)
+ + maybe use expect
+ [ ] send sleep
+ + make sure we sleep
+ [ ] send 'w'
+ + make sure we dont WD time out
+ [ ] check for unlikely WD/sleep/reboot events
+ + especially under nasty conditions
+
+[ ] check how accurate the timing is

+
+[ ] Will 5V levels from PIC play nicely with 3V3 levels of router -
+check data sheets!

+; 4800 BAUD RS232 OUTPUT\r
+; ======================\r
+; \r
+; The following line is printed every time you send 'w' or '.', if you\r
+; send nothing to wispcar it will remain silent. The specific chars\r
+; minimise the chance of wispcar interfering with your boot loader.\r

+; wispcar 040 031 - 032 012 000 0 000 w---reason for last restart\r
+; b - Wispcar (re)booted \r
+; w - watchdog timer fired \r
+; s - we went to sleep\r
+; - - restart flag reset\r
+;\r
+; COMMANDS\r
+; ========\r
+;\r
+; 1/ Send a 'w' every WD_TIMEOUT seconds to prevent Watchdog timer\r
+; firing and cutting power.\r
+;\r
+; 2/ Send a '.' to report status without resetting watchdog.\r
+;\r
+; 3/ Send the string 'sleepxyz' to cut the power for xyz seconds,\r
+; where x,y and z are digits in the range 0-9. If any part of the\r
+; string is invalid it will be ignored. Wait 5 seconds and start\r
+; again.\r
+;\r
+; 4/ Wispcar cannot rx and tx RS232 at the same time. Wait until after\r
+; the current output has finished to send the next command. It is best to\r
+; wait until just after the output line is received by the host, then\r
+; send your command. If the command (such as sleep) gets messed up,\r
+; just wait 5 seconds and wispcar will reset it's internal state\r
+; machine. You can then try again.\r
+;\r
+; 4/ The final field is reset to a space when a 'w' is sent to\r
+; Wispcar. This field lets the host know just _why_ it was rebooted.\r

+;\r
+; WISPCAR modified for EV battery testing. When watchdog fires PowerSwitch\r
+; (pin 6) stays off until the host sends a "w". This switches off current\r
+; to the battery under test if the host side dies. This mod is just a hack\r
+; for now.\r
+;\r
+;\r
+; PIC12F510 Assembler program, MPLAB V8.10 IDE used to build.\r

+; 4800 BAUD RS232 OUTPUT\r
+; ======================\r
+; \r
+; The following line is printed every time you send 'w' or '.', if you\r
+; send nothing to wispcar it will remain silent. The specific chars\r
+; minimise the chance of wispcar interfering with your boot loader.\r

+; | | | | | | | Sleep state machine state\r
+; | | | | | | | | Sleep timeout counter\r
+; | | | | | | | | | \r
+; wispcar 040 031 - 032 012 000 0 000 w---reason for last restart\r
+; b - Wispcar (re)booted \r
+; w - watchdog timer fired \r
+; s - we went to sleep\r
+; - - restart flag reset\r
+;\r
+; COMMANDS\r
+; ========\r
+;\r
+; 1/ Send a 'w' every WD_TIMEOUT seconds to prevent Watchdog timer\r
+; firing and cutting power.\r
+;\r
+; 2/ Send a '.' to report status without resetting watchdog.\r
+;\r
+; 3/ Send the string 'sleepxyz' to cut the power for xyz seconds,\r
+; where x,y and z are digits in the range 0-9. If any part of the\r
+; string is invalid it will be ignored. Wait 5 seconds and start\r
+; again.\r
+;\r
+; 4/ Wispcar cannot rx and tx RS232 at the same time. Wait until after\r
+; the current output has finished to send the next command. It is best to\r
+; wait until just after the output line is received by the host, then\r
+; send your command. If the command (such as sleep) gets messed up,\r
+; just wait 5 seconds and wispcar will reset it's internal state\r
+; machine. You can then try again.\r
+;\r
+; 4/ The final field is reset to a space when a 'w' is sent to\r
+; Wispcar. This field lets the host know just _why_ it was rebooted.\r

- GNU GENERAL PUBLIC LICENSE
- Version 2, June 1991
-
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.
- 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
- Preamble
-
- The licenses for most software are designed to take away your
-freedom to share and change it. By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users. This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it. (Some other Free Software Foundation software is covered by
-the GNU Library General Public License instead.) You can apply it to
-your programs, too.
-
- When we speak of free software, we are referring to freedom, not
-price. Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
- To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
- For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have. You must make sure that they, too, receive or can get the
-source code. And you must show them these terms so they know their
-rights.
-
- We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
- Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software. If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
- Finally, any free program is threatened constantly by software
-patents. We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary. To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
- The precise terms and conditions for copying, distribution and
-modification follow.
-\f
- GNU GENERAL PUBLIC LICENSE
- TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
- 0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License. The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language. (Hereinafter, translation is included without limitation in
-the term "modification".) Each licensee is addressed as "you".
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope. The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
- 1. You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
- 2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
- a) You must cause the modified files to carry prominent notices
- stating that you changed the files and the date of any change.
-
- b) You must cause any work that you distribute or publish, that in
- whole or in part contains or is derived from the Program or any
- part thereof, to be licensed as a whole at no charge to all third
- parties under the terms of this License.
-
- c) If the modified program normally reads commands interactively
- when run, you must cause it, when started running for such
- interactive use in the most ordinary way, to print or display an
- announcement including an appropriate copyright notice and a
- notice that there is no warranty (or else, saying that you provide
- a warranty) and that users may redistribute the program under
- these conditions, and telling the user how to view a copy of this
- License. (Exception: if the Program itself is interactive but
- does not normally print such an announcement, your work based on
- the Program is not required to print an announcement.)
-\f
-These requirements apply to the modified work as a whole. If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works. But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
- 3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
- a) Accompany it with the complete corresponding machine-readable
- source code, which must be distributed under the terms of Sections
- 1 and 2 above on a medium customarily used for software interchange; or,
-
- b) Accompany it with a written offer, valid for at least three
- years, to give any third party, for a charge no more than your
- cost of physically performing source distribution, a complete
- machine-readable copy of the corresponding source code, to be
- distributed under the terms of Sections 1 and 2 above on a medium
- customarily used for software interchange; or,
-
- c) Accompany it with the information you received as to the offer
- to distribute corresponding source code. (This alternative is
- allowed only for noncommercial distribution and only if you
- received the program in object code or executable form with such
- an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it. For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable. However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-\f
- 4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License. Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
- 5. You are not required to accept this License, since you have not
-signed it. However, nothing else grants you permission to modify or
-distribute the Program or its derivative works. These actions are
-prohibited by law if you do not accept this License. Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
- 6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions. You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
- 7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License. If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all. For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices. Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-\f
- 8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded. In such case, this License incorporates
-the limitation as if written in the body of this License.
-
- 9. The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time. Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number. If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation. If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
- 10. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission. For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this. Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
- NO WARRANTY
-
- 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
- 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
-POSSIBILITY OF SUCH DAMAGES.
-
- END OF TERMS AND CONDITIONS
-\f
- How to Apply These Terms to Your New Programs
-
- If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
- To do so, attach the following notices to the program. It is safest
-to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
- <one line to give the program's name and a brief idea of what it does.>
- Copyright (C) <year> <name of author>
-
- This program is free software; you can redistribute it and/or modify
- it under the terms of the GNU General Public License as published by
- the Free Software Foundation; either version 2 of the License, or
- (at your option) any later version.
-
- This program is distributed in the hope that it will be useful,
- but WITHOUT ANY WARRANTY; without even the implied warranty of
- MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
- GNU General Public License for more details.
-
- You should have received a copy of the GNU General Public License
- along with this program; if not, write to the Free Software
- Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
-
-
-Also add information on how to contact you by electronic and paper mail.
-
-If the program is interactive, make it output a short notice like this
-when it starts in an interactive mode:
-
- Gnomovision version 69, Copyright (C) year name of author
- Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
- This is free software, and you are welcome to redistribute it
- under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License. Of course, the commands you use may
-be called something other than `show w' and `show c'; they could even be
-mouse-clicks or menu items--whatever suits your program.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the program, if
-necessary. Here is a sample; alter the names:
-
- Yoyodyne, Inc., hereby disclaims all copyright interest in the program
- `Gnomovision' (which makes passes at compilers) written by James Hacker.
-
- <signature of Ty Coon>, 1 April 1989
- Ty Coon, President of Vice
-
-This General Public License does not permit incorporating your program into
-proprietary programs. If your program is a subroutine library, you may
-consider it more useful to permit linking proprietary applications with the
-library. If this is what you want to do, use the GNU Library General
-Public License instead of this License.

-The TAPR Open Hardware License
-Version 1.0 (May 25, 2007)
-Copyright 2007 TAPR – http://www.tapr.org/OHL
-
-PREAMBLE
-
-Open Hardware is a thing - a physical artifact, either electrical or
-mechanical - whose design information is available to, and usable by,
-the public in a way that allows anyone to make, modify, distribute, and
-use that thing. In this preface, design information is called
-"documentation" and things created from it are called "products."
-
-The TAPR Open Hardware License ("OHL") agreement provides a legal
-framework for Open Hardware projects. It may be used for any kind of
-product, be it a hammer or a computer motherboard, and is TAPR's
-contribution to the community; anyone may use the OHL for their Open
-Hardware project.
-
-Like the GNU General Public License, the OHL is designed to guarantee
-your freedom to share and to create. It forbids anyone who receives
-rights under the OHL to deny any other licensee those same rights to
-copy, modify, and distribute documentation, and to make, use and
-distribute products based on that documentation.
-
-Unlike the GPL, the OHL is not primarily a copyright license. While
-copyright protects documentation from unauthorized copying, modification,
-and distribution, it has little to do with your right to make, distribute,
-or use a product based on that documentation. For better or worse, patents
-play a significant role in those activities. Although it does not prohibit
-anyone from patenting inventions embodied in an Open Hardware design, and
-of course cannot prevent a third party from enforcing their patent rights,
-those who benefit from an OHL design may not bring lawsuits claiming that
-design infringes their patents or other intellectual property.
-
-The OHL addresses unique issues involved in the creation of tangible,
-physical things, but does not cover software, firmware, or code loaded
-into programmable devices. A copyright-oriented license such as the GPL
-better suits these creations.
-
-How can you use the OHL, or a design based upon it? While the terms and
-conditions below take precedence over this preamble, here is a summary:
-
-* You may modify the documentation and make products based upon it.
-
-* You may use products for any legal purpose without limitation.
-
-* You may distribute unmodified documentation, but you must include the
-complete package as you received it.
-
-* You may distribute products you make to third parties, if you either
-include the documentation on which the product is based, or make it
-available without charge for at least three years to anyone who requests
-it.
-
-* You may distribute modified documentation or products based on it, if
-you:
- * License your modifications under the OHL.
- * Include those modifications, following the requirements stated
- below.
- * Attempt to send the modified documentation by email to any of the
- developers who have provided their email address. This is a good
- faith obligation – if the email fails, you need do nothing more
- and may go on with your distribution.
-
-* If you create a design that you want to license under the OHL, you
-should:
- * Include this document in a file named LICENSE (with the appropriate
- extension) that is included in the documentation package.
- * If the file format allows, include a notice like “Licensed under
- the TAPR Open Hardware License (www.tapr.org/OHL)” in each
- documentation file. While not required, you should also include
- this notice on printed circuit board artwork and the product
- itself; if space is limited the notice can be shortened or
- abbreviated.
- * Include a copyright notice in each file and on printed circuit
- board artwork.
- * If you wish to be notified of modifications that others may make,
- include your email address in a file named “CONTRIB.TXT” or
- something similar.
-
-* Any time the OHL requires you to make documentation available to
-others, you must include all the materials you received from the
-upstream licensors. In addition, if you have modified the
-documentation:
- * You must identify the modifications in a text file (preferably
- named "CHANGES.TXT") that you include with the documentation.
- That file must also include a statement like "These modifications
- are licensed under the TAPR Open Hardware License."
- * You must include any new files you created, including any
- manufacturing files (such as Gerber files) you create in the
- course of making products.
- * You must include both "before" and "after" versions of all files
- you modified.
- * You may include files in proprietary formats, but you must also
- include open format versions (such as Gerber, ASCII, Postscript,
- or PDF) if your tools can create them.
-
-TERMS AND CONDITIONS
-
-1. Introduction
-1.1 This Agreement governs how you may use, copy, modify, and
-distribute Documentation, and how you may make, have made, and
-distribute Products based on that Documentation. As used in this
-Agreement, to "distribute" Documentation means to directly or indirectly
-make copies available to a third party, and to "distribute" Products
-means to directly or indirectly give, loan, sell or otherwise transfer
-them to a third party.
-
-1.2 "Documentation" includes:
- (a) schematic diagrams;
- (b) circuit or circuit board layouts, including Gerber and other
- data files used for manufacture;
- (c) mechanical drawings, including CAD, CAM, and other data files
- used for manufacture;
- (d) flow charts and descriptive text; and
- (e) other explanatory material.
-Documentation may be in any tangible or intangible form of expression,
-including but not limited to computer files in open or proprietary
-formats and representations on paper, film, or other media.
-
-1.3 "Products" include:
- (a) circuit boards, mechanical assemblies, and other physical parts
- and components;
- (b) assembled or partially assembled units (including components
- and subassemblies); and
- (c) parts and components combined into kits intended for assembly
- by others;
-which are based in whole or in part on the Documentation.
-
-1.4 This Agreement applies to any Documentation which contains a
-notice stating it is subject to the TAPR Open Hardware License, and to
-all Products based in whole or in part on that Documentation. If
-Documentation is distributed in an archive (such as a "zip" file) which
-includes this document, all files in that archive are subject to this
-Agreement unless they are specifically excluded. Each person who
-contributes content to the Documentation is referred to in this
-Agreement as a "Licensor."
-
-1.5 By (a) using, copying, modifying, or distributing the
-Documentation, or (b) making or having Products made or distributing
-them, you accept this Agreement, agree to comply with its terms, and
-become a "Licensee." Any activity inconsistent with this Agreement will
-automatically terminate your rights under it (including the immunities
-from suit granted in Section 2), but the rights of others who have
-received Documentation, or have obtained Products, directly or
-indirectly from you will not be affected so long as they fully comply
-with it themselves.
-
-1.6 This Agreement does not apply to software, firmware, or code
-loaded into programmable devices which may be used in conjunction with
-Documentation or Products. Such software is subject to the license
-terms established by its copyright holder(s).
-
-2. Patents
-2.1 Each Licensor grants you, every other Licensee, and every
-possessor or user of Products a perpetual, worldwide, and royalty-free
-immunity from suit under any patent, patent application, or other
-intellectual property right which he or she controls, to the extent
-necessary to make, have made, possess, use, and distribute Products.
-This immunity does not extend to infringement arising from modifications
-subsequently made by others.
-
-2.2 If you make or have Products made, or distribute Documentation
-that you have modified, you grant every Licensor, every other Licensee,
-and every possessor or user of Products a perpetual, worldwide, and
-royalty-free immunity from suit under any patent, patent application, or
-other intellectual property right which you control, to the extent
-necessary to make, have made, possess, use, and distribute Products.
-This immunity does not extend to infringement arising from modifications
-subsequently made by others.
-
-2.3 To avoid doubt, providing Documentation to a third party for the
-sole purpose of having that party make Products on your behalf is not
-considered "distribution," and a third party's act of making Products
-solely on your behalf does not cause that party to grant the immunity
-described in the preceding paragraph.
-
-2.4 These grants of immunity are a material part of this Agreement,
-and form a portion of the consideration given by each party to the
-other. If any court judgment or legal agreement prevents you from
-granting the immunity required by this Section, your rights under this
-Agreement will terminate and you may no longer use, copy, modify or
-distribute the Documentation, or make, have made, or distribute
-Products.
-
-3. Modifications
-You may modify the Documentation, and those modifications will become
-part of the Documentation. They are subject to this Agreement, as are
-Products based in whole or in part on them. If you distribute the
-modified Documentation, or Products based in whole or in part upon it,
-you must email the modified Documentation in a form compliant with
-Section 4 to each Licensor who has provided an email address with the
-Documentation. Attempting to send the email completes your obligations
-under this Section and you need take no further action if any address
-fails.
-
-4. Distributing Documentation
-4.1 You may distribute unmodified copies of the Documentation in its
-entirety in any medium, provided that you retain all copyright and other
-notices (including references to this Agreement) included by each
-Licensor, and include an unaltered copy of this Agreement.
-4.2 You may distribute modified copies of the Documentation if you
-comply with all the requirements of the preceding paragraph and:
- (a) include a prominent notice in an ASCII or other open format
- file identifying those elements of the Documentation that you
- changed, and stating that the modifications are licensed under
- the terms of this Agreement;
- (b) include all new documentation files that you create, as well as
- both the original and modified versions of each file you change
- (files may be in your development tool's native file format,
- but if reasonably possible, you must also include open format,
- such as Gerber, ASCII, Postscript, or PDF, versions);
- (c) do not change the terms of this Agreement with respect to
- subsequent licensees; and
- (d) if you make or have Products made, include in the Documentation
- all elements reasonably required to permit others to make
- Products, including Gerber, CAD/CAM and other files used for
- manufacture.
-
-5. Making Products
-5.1 You may use the Documentation to make or have Products made,
-provided that each Product retains any notices included by the Licensor
-(including, but not limited to, copyright notices on circuit boards).
-5.2 You may distribute Products you make or have made, provided that
-you include with each unit a copy of the Documentation in a form
-consistent with Section 4. Alternatively, you may include either (i) an
-offer valid for at least three years to provide that Documentation, at
-no charge other than the reasonable cost of media and postage, to any
-person who requests it; or (ii) a URL where that Documentation may be
-downloaded, available for at least three years after you last distribute
-the Product.
-
-6. NEW LICENSE VERSIONS
-TAPR may publish updated versions of the OHL which retain the same
-general provisions as the present version, but differ in detail to
-address new problems or concerns, and carry a distinguishing version
-number. If the Documentation specifies a version number which applies
-to it and "any later version", you may choose either that version or any
-later version published by TAPR. If the Documentation does not specify
-a version number, you may choose any version ever published by TAPR.
-TAPR owns the copyright to the OHL, but grants permission to any person
-to copy, distribute, and use it in unmodified form.

- + make sure PIC does not hang
-
-Specs:
------
-
-1/ Measures Vbat and Ibat.
-
- Vbat between 5 and 60V
- Ibat between 0 and 5A
-
- Measures Vbat and Ibat and reports every 1 sec to Host.
-
-2/ Watchdog
-
- Fires if no RS232 rx for TBD1 secs from host
- Power is shut off for 5 seconds then reapplied
-
-3/ Sleep
-
- Send "sleepXXXX" to put power supply to sleep for XXXX seconds
-
-4/ Current consumption (estimated)
-
- Vbat = 30V I=2mA
- Vbat = 5V I=2mA
-
- Note: we need to work out a way to get 60V operation, 78L05
- regulator can't go above 35V.
-
-References
-----------
-
-1/ Zener power supply design:
-
- http://www.kpsec.freeuk.com/powersup.htm
-
-2/ PIC10F510 datasheet from Microchip
-
-3/ 78L05 datasheet
-
-4/ IRF9540 datasheet
-
-Credits
--------
-
-Tim Ansell (Mithro) for lending me his PIC collection and programmer
-Yahel Ben-David
-
-Notes
------
-
-1/ IRF9640 FET was selected largely at random. At 19A max it may be
-overkill, a cheaper FET may be more suitable.
-
-2/ The RS232 polarity may need to change when directly connected to a
-router without level conversion, see reference docs for RS232 software
-UART code in wispcar.asm. I used a MAX232 type chip for interfacing
-the RS232 tx & rx to a PC's serial port for testing.
-
-Gotchas
--------
-
-1/ On the PIC12F510 we can only use 'call' to call an address in the
-first 256 bytes, so put all funcs at the start of the program, main at
-the end.
-
-2/ If the RS232 characters have occasional errors, the internal clock
-oscillator may need tweaking. You can check the baud rate of the
-RS232 signals using an oscilloscope, at 4800 baud the bit period
-should be 208us. See PIC data sheet for information on adjusting the
-internal oscillator.
-
-3/ The Vce(max) rating of Q2 is 35V, and Vgs(max) of Q1 +/- 20V. As
-R1/R2 form a voltage divider I think this sets the maximum Vbat at 35V
-for the current version, i.e. Q1 will pop first (as Vgs will hit 20V
-when Vbat=40V). Need higher Vce Q2 or change circuit to limit
-Vgs(max). Need to make sure sufficient Vgs to switch on Q1 at low
-Vbat. Maybe two versions with different R1/R2?
-
-4/ Current Sensor resistor values. When building the first soldered
-prototype I found that residual flux messed up the 10M R11 feedback
-resistor. Scraping flux away and cleaning with solvent brought the
-resistance back up again. This could be a problem with home
-construction, and possibly humid environments. Perhaps we should
-scale resistors down to say 100k/10k voltage dividers, 1M R11?
-
-5/ When building the first soldered prototype I found that the
-position of the ground wires carrying high current caused the current
-sensor to stop working (stuck at 0V). U2 GND and the GND of R7, R9,
-R10 where at different places along the GND track carrying 0.5A. This
-caused a voltage drop of about 5mV between the two GNDs. I moved the
-ground connection (made the GND in GND out points close to each other
-so 0.5A was only flowing thru a short section of track) and the
-current sensor started working again. This suggests a carefully laid
-out PCB is a good idea.
-
-6/ The voltage on pins 2 & 3 of U2 (+/i op-amp input) should be within
-10 mV of each other with U2 unplugged. A greater difference indicates
-one of the resistor values is wrong.
-

-[ ] Note 1% R's on schematic
-[X] make sure we can't stall in RS232 input routine
- + need a way to get around this.....
- + malformed RS323 could cause a hang
- + maybe better to just look at h/l transition or something?
- + sep pic for sleep function?
- + solution: integrate 1 sec delay with RS232 rx
-[ ] Limitations
- + need to send full command before 1 second delay?
- + like send command immediately after ADC data
- + need automatic reset from fragment
- + like once every second
- + or can it be spread over cycles?
-[ ] enable PIC watchdog timer
- + how can we test?
-[ ] How repeatable is current sensor?
- + y intercept (DC offset)
- + slope
- + maybe build a few a check
-[ ] make sure all RS232 chars OK
- + how to prog with calibrated clock?
- + check baud rate
- + is max232 OK at Vcc=5V?
-[ ] programming procedure to preserve osccal
-[X] make function to print decimal, rather than repeating all that code
- + we can't as call stack is only two levels deep and we are at the limit
-
-[ ] automatic thrash tests (repeat each one for hours/days)
- + maybe use expect
- [ ] send sleep
- + make sure we sleep
- [ ] send 'w'
- + make sure we dont WD time out
- [ ] check for unlikely WD/sleep/reboot events
- + especially under nasty conditions
-
-[ ] check how accurate the timing is
- + is 1 sec delay accurate?
-
-[ ] work out how to run from 60V
- + 78L05 pops at 35V
-
-[ ] Will 5V levels from PIC play nicely with 3V3 levels of router -
-check data sheets!

-; ======================\r
-; \r
-; The following line is printed every time you send 'w' or '.', if you\r

-; wispcar 040 031 - 032 012 000 0 000 w---reason for last restart\r
-; b - Wispcar (re)booted \r
-; w - watchdog timer fired \r
-; s - we went to sleep\r
-; - - restart flag reset\r
-;\r
-; COMMANDS\r
-; ========\r
-;\r
-; 1/ Send a 'w' every WD_TIMEOUT seconds to prevent Watchdog timer\r
-; firing and cutting power.\r
-;\r
-; 2/ Send a '.' to report status without resetting watchdog.\r
-;\r
-; 3/ Send the string 'sleepxyz' to cut the power for xyz seconds,\r
-; where x,y and z are digits in the range 0-9. If any part of the\r
-; string is invalid it will be ignored. Wait 5 seconds and start\r
-; again.\r
-;\r
-; 4/ Wispcar cannot rx and tx RS232 at the same time. Wait until after\r
-; the current output has finished to send the next command. It is best to\r
-; wait until just after the output line is received by the host, then\r
-; send your command. If the command (such as sleep) gets messed up,\r
-; just wait 5 seconds and wispcar will reset it's internal state\r
-; machine. You can then try again.\r
-;\r
-; 4/ The final field is reset to a space when a 'w' is sent to\r
-; Wispcar. This field lets the host know just _why_ it was rebooted.\r

-;\r
-;\r
-; 4800 BAUD RS232 OUTPUT\r
-; ======================\r
-; \r
-; The following line is printed every time you send 'w' or '.', if you\r
-; send nothing to wispcar it will remain silent. The specific chars\r
-; minimise the chance of wispcar interfering with your boot loader.\r

-; | | | | | | Watchdog fire counter\r
-; | | | | | | | Sleep state machine state\r
-; | | | | | | | | Sleep timeout counter\r
-; | | | | | | | | | \r
-; wispcar 040 031 - 032 012 000 0 000 w---reason for last restart\r
-; b - Wispcar (re)booted \r
-; w - watchdog timer fired \r
-; s - we went to sleep\r
-; - - restart flag reset\r
-;\r
-; COMMANDS\r
-; ========\r
-;\r
-; 1/ Send a 'w' every WD_TIMEOUT seconds to prevent Watchdog timer\r
-; firing and cutting power.\r
-;\r
-; 2/ Send a '.' to report status without resetting watchdog.\r
-;\r
-; 3/ Send the string 'sleepxyz' to cut the power for xyz seconds,\r
-; where x,y and z are digits in the range 0-9. If any part of the\r
-; string is invalid it will be ignored. Wait 5 seconds and start\r
-; again.\r
-;\r
-; 4/ Wispcar cannot rx and tx RS232 at the same time. Wait until after\r
-; the current output has finished to send the next command. It is best to\r
-; wait until just after the output line is received by the host, then\r
-; send your command. If the command (such as sleep) gets messed up,\r
-; just wait 5 seconds and wispcar will reset it's internal state\r
-; machine. You can then try again.\r
-;\r
-; 4/ The final field is reset to a space when a 'w' is sent to\r
-; Wispcar. This field lets the host know just _why_ it was rebooted.\r
