A long time has passed since GorillaCoder announced alpha 1 of XmegaDuino, and the time has come to release a new version to the public.
The code repository is available at https://github.com/akafugu/Xmegaduino, and pre-compiled binaries are here: https://github.com/akafugu/Xmegaduino/downloads.
This release supports Xplain from Atmel, Sparkfun's XMega100 breakout board and Akafuino X from Akafugu.
The basics Arduino functionality is already working. This includes functionality such as digital I/O, analog I/O, interrupts, serial I/O, PWM, millis/micros, delay/delayMicroseconds.
The Wire library has been modified so sketches that uses Wire should work out-of-the-box. Included is also the xmDAC library from the xmlibrary (http://code.google.com/p/xmlibraries/).
If you decide to give XmegaDuino a try, please tell us how it went so we can continue improving it.
