GH60 Satan Firmware

This is a custom firmware for the GH60 Satan. It uses the LUFA USB stack so you need to flash the LUFA DFU bootloader hex file to your atmega32u4.

Modify src/keymap.c to your liking. The list of all keys is in include/keycodes.h

Features

• LED support (for my version, it's basically Caps Lock and everything else)
• Layers (up to 4)
• Debouncing

Building

make

You will need to have avr-gcc.

Flashing to the board

Again, this firmware uses the LUFA USB stack so make sure you've got the LUFA bootloader on your atmega.

make flash flashes the built firmware to the board. make launch will run the program on the board. You can also just power cycle your GH60; the bootloader will automatically run the firmware unless you've changed your fuses.

Keymaps

On Windows and Linux, I like to use the regular keymap. Note I've moved Escape to the bottom right since I really need the tilde at the regular spot (going to home directories, etc.).

{ KC_GRAVE,    KC_1,    KC_2,    KC_3,     KC_4,    KC_5,     KC_6,    KC_7,     KC_8,    KC_9,     KC_0,      KC_MINUS,    KC_EQUAL,    KC_BSPACE },
{ KC_TAB,      KC_Q,    KC_W,    KC_E,     KC_R,    KC_T,     KC_Y,    KC_U,     KC_I,    KC_O,     KC_P,      KC_LBRACKET, KC_RBRACKET, KC_BSLASH },
{ KC_CAPSLOCK, KC_A,    KC_S,    KC_D,     KC_F,    KC_G,     KC_H,    KC_J,     KC_K,    KC_L,     KC_SCOLON, KC_QUOTE,    KC_NONE,     KC_ENTER },
{ KC_LSHIFT,   KC_NONE, KC_Z,    KC_X,     KC_C,    KC_V,     KC_B,    KC_N,     KC_M,    KC_COMMA, KC_DOT,    KC_SLASH,    KC_NONE,     KC_RSHIFT },
{ KC_LCTRL,    KC_LGUI, KC_LALT, KC_NONE,  KC_NONE, KC_SPACE, KC_NONE, KC_NONE,  KC_NONE, KC_NONE,  KC_LAYER_0, KC_LAYER_1, KC_MUTE,     KC_ESCAPE }

On OS X, I swap the Alt (Alt) and Command (Win) keys so I don't need to stretch my fingers as far.

{ KC_GRAVE,    KC_1,    KC_2,    KC_3,     KC_4,    KC_5,     KC_6,    KC_7,     KC_8,    KC_9,     KC_0,      KC_MINUS,    KC_EQUAL,    KC_BSPACE },
{ KC_TAB,      KC_Q,    KC_W,    KC_E,     KC_R,    KC_T,     KC_Y,    KC_U,     KC_I,    KC_O,     KC_P,      KC_LBRACKET, KC_RBRACKET, KC_BSLASH },
{ KC_CAPSLOCK, KC_A,    KC_S,    KC_D,     KC_F,    KC_G,     KC_H,    KC_J,     KC_K,    KC_L,     KC_SCOLON, KC_QUOTE,    KC_NONE,     KC_ENTER },
{ KC_LSHIFT,   KC_NONE, KC_Z,    KC_X,     KC_C,    KC_V,     KC_B,    KC_N,     KC_M,    KC_COMMA, KC_DOT,    KC_SLASH,    KC_NONE,     KC_RSHIFT },
{ KC_LCTRL,    KC_LALT, KC_LGUI, KC_NONE,  KC_NONE, KC_SPACE, KC_NONE, KC_NONE,  KC_NONE, KC_NONE,  KC_LAYER_0, KC_LAYER_1, KC_MUTE,     KC_ESCAPE }

You can find all the possible keys in include/keycodes.h
