This core will NOT support ATtiny x14/x17/x18 (ATtiny406, ATtiny212/412, ATtiny214/414/814/1614, ATtiny416/816/1616/3216, ATtiny417/817/1617/3217, etc) or other chips with the "xMega-like" peripherals. A very large amount of work would be required to support these parts. See #174 for details. It looks like the Arduino team is planning to release an official board based on a part with similar peripherals; after this is done, work could begin on porting that to the similar ATTiny parts.

These are very exciting parts - but the process of supporting them in Arduino is a monumental task as every single library function must be rewritten. The peripherals (even GPIO) are pic-like, not AVR-like, so they need their own implementation of EVERYTHING - serial, digitalread/etc, wire, spi, pwm, adc input.

This is a huge task and would be covered by a separate core. I do not expect to have time to do this - I certainly cannot do it alone. Talk to me on gitter if you're able to put time into this.

Also, until the Arduino AVR official board package's compiler is updated to a version that supports these parts, they wouldn't be really usable with the Arduino IDE.

When you consider the amount of development effort involved, I legitimately question whether adding support for these parts makes sense - you can't leverage the existing arduino libraries any more than you could with a totally different architecture. And at that point, aren't there ARM chips that are more attractive?

The only thing AVR about these is the instruction set - as far as I can tell, it's PIC peripherals bolted onto an AVR core.

De profundis  :( :( :(
Merci pour l'info.
