Kitten Paw controller firmware
|
||||||
|
======================
|
||||||
|
Custom controller for the Costar Majestouch keyboard designed by bpiphany.
|
||||||
|
|
||||||
|
*Note that this is not the official firmware*
|
||||||
|
|
||||||
|
Build
|
||||||
|
-----
|
||||||
|
Move to this directory then just run `make` like:
|
||||||
|
|
||||||
|
$ make -f Makefile.lufa
|
||||||
|
|
||||||
|
At the moment only the LUFA stack is supported.
|
||||||
|
|
||||||
|
|
||||||
|
Bootloader
|
||||||
|
---------
|
||||||
|
To enter bootloader by hardware use a magnet above the controller before connecting the usb cable.
|
||||||
|
|
||||||
|
It is still possible to use Boot Magic and Command (LSFT+RSFT+PAUS) to access the bootloader though.
