From the hands of Tero Koskinen we get improved support in AVR-Ada for Arduino Mega 2560 and Attiny13a/Attiny2313:
These changes improve support for Atmega2560, Attiny13a, and Attiny2313 processors. Attiny13a and Attiny2313 are pretty uninteresting, although common, AVR processors. I happen to use them in my projects because they are cheap and that is why I also wanted better support for them.
I micro-blogged about this a few days ago and it was amazing to see how many people clicked on the link. Apparently there’s a HUGE amount of interest for AVR-Ada among identi.ca users.
