Button Firmware

That was trivial

Flashing

Begin by compiling everything, then flashing the bootloader with your programmer of choice.

# start by compiling everything
make
# set the fuse bits
make fuse
# flash the bootloader
make flash

Now you can program via a USB connection.

make flash-firmware
