Add support for panStamp AVR

[gandy92]

Is it possible to add support for the panStamp AVR and panStamp NRG boards?

• Vendor: http://www.panstamp.com/
• panStamp AVR: https://github.com/panStamp/panstamp/wiki/panStamp%20AVR.-Technical%20details
• panStamp NRG: https://github.com/panStamp/panstamp/wiki/panStamp%20NRG.-Technical%20details
• Libraries for panStamp specific hardware: https://github.com/panStamp/panstamp

Thank you for adding support for panstamp so promptly 👍

I managed to successfully build the panstamp-blink.ino. However, I have a few issues compiling a sketch that uses the Wire lib, similar to what is mentioned here: http://www.panstamp.org/forum/archive/index.php/thread-3978.html Apparently, using the panstamp libraries requires a few patches to the libraries shipped with arduino.

Should I open a new issue covering this? Shall I provide more information, or a testcase?

I looked into this more closely, apparently they just rename twi.c from libraries/Wire/utility to twi.cpp to make it work. Would this be a viable solution?

@gandy92 thanks for report. I've just opened new issue #133 . It should resolve this problem.

P.S: You can currently avoid this problem via adding specific libs to your project libs directory. These libs have more higher priority then framework's libs. Just copy PanStamp's Wire lib to projects libs/Wire. Did it help you?

[gandy92]

Thanks for the workaround. For a preliminary fix I manually copied the libraries to the platformio directories. Your solution is much more elegant, though, I will try this with a clean installation, tomorrow.

Ok, I will wait for your results.

P.S: Please restore default PlatformIO packages. Just uninstall/install specified platforms or remove totally ~/.platformio dir.

Removed .platformio dir and copied panstamp-avr specific libraries to lib/

Worked fine for both of my projects. 👍
