Firmware

Building requires an avr-gcc toolchain, in the firmware/ directory, to build run:

make main.hex

Flashing the firmware on the device requires avrdude and a compatible hardware programmer. Default configuration is stored at the beginning of the Makefile. To program with the default configuration, run:

make flash

Fuses can be configured running:

make fuses

Hardware

All hardware files (schematic, layout and libraries) are in CadSoft Eagle format.
