Compiling firmwares

In order to compile firmwares, avr-gcc is required. Please ensure you have it installed before moving to next step.

You need to select the correct MODEL and LAYOUT variables in the Makefile

BOARD = hib_liber
LAYOUT = ansi_iso_jis
MCU = atmega32u4
F_CPU = 16000000
B_LOADER = \"jmp\ 0x7000\"

Then run the make command in a terminal. Always run a make clean first.

make clean; make

If the process is successful, you would find binary firmware with extension .hex inside the binaries folder

Flashing the controller

Make sure you install dfu-programmer first.

dfu-programmer atmega32u4 erase
dfu-programmer atmega32u4 flash avr_keyboard.hex
dfu-programmer atmega32u4 start
