Build firmware
|
|
|
|
--------------
|
|
|
|
$ git clone git://github.com/tmk/tmk_keyboard.git
|
|
|
|
$ cd tmk_keyboard
|
|
|
|
$ git checkout usb_hid
|
|
|
|
$ git submodule init
|
|
|
|
$ git submodule update
|
|
|
|
|
|
|
|
and download LUFA and unzip under protocol/lufa and edit LUFA_PATH in protocol/lufa.mk. Then,
|
|
|
|
|
|
|
|
$ cd converter/usb_usb
|
|
|
|
$ make
|
|
|
|
|
|
|
|
You will get usb_usb.hex if you are lucky.

|
|
$ avrdude -patmega32u4 -cavr109 -PCOM17 -b57600 -Uflash:w:usb_usb.hex
