After the arduous task of getting Python to cross-compile for the AVR32, the next step was to relax a bit and take a stab at getting some preliminary communication with the I/O ports going (which is the first step towards … Continue reading →

So for a (hopefully) evil advantage in this robotics competition, I decided to use an NGW100 AVR32-based embedded Linux platform. This board was interesting because it is cheap, and seemingly is powerful enough to let me program the bot in … Continue reading →

I’ve had a Microsoft Wireless Comfort Keyboard for years, however I have somehow managed to ignore most of the extra keys that don’t work out of the box until now (I got them working at one point, but something happened … Continue reading →
