Lightpad keypad firmware | |||
====================== | |||
Korean custom keypad designed by Duck. | |||
*Note that this is not the official firmware* | |||
Supported models | |||
---------------- | |||
All pcb options are supported. | |||
Build | |||
----- | |||
Move to this directory then just run `make` like: | |||
$ make -f Makefile.lufa | |||
Bootloader | |||
--------- | |||
The PCB is hardwired to run the bootloader if the key at the `top left` position is held down when connecting the keyboard. | |||
It is still possible to use Boot Magic and Command to access the bootloader though. |
