SparkFun atmega32u4 Breakout

So, while this board uses an atmega32u4 it has a major problem. It will always boot into the bootloader and wait for the char 'e' to be sent. So instead, I just wrote the tmk firmware over the bootloader.

• Board - https://www.sparkfun.com/products/11117
• Github - https://github.com/sparkfun/32U4_Breakout_Board
• LUFA-130303 bootloader - File:BootloaderCDC.hex.gz
  • avrdude -p atmega32u4 -P /dev/ttyACM0 -c usbasp -U flash:w:BootloaderCDC.hex
• Program tmk over the bootloader
  • avrdude -p atmega32u4 -P /dev/ttyACM0 -c usbasp -U flash:w:ps2_usb_lufa.hex

ps/2 cable

I stole a female ps/2 port from a qcat.

              o  |  o <-- Blue (clock)
Red (vcc) --> o  |  o <-- Green (gnd)
                o o <-- Yellow (data)

Keymap macro

#define KEYMAP( \
/* these parameters indicate keyboard layout order */
) { \
/* you must place C array notation of your matrix structure here */
}
