The Ghost Squid controller
==========================
Custom controller for the Cooler Master QuickFire XT 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.
