Connect Wires

In case of Teensy2.0(ATMega32U4):

1. Connect Vcc and GND.
2. Connect Clock and Data line.
   • Clock is on PD1 and Data on PD2.
3. Optionally you need pull-up register. 1KOhm is OK?

To change pin configuration edit config.h.

Build Firmware

Just run make:

$ make

To select keymap:

$ make KEYMAP=[plain|...]

Keymap

Several version of keymap are available in advance but you are recommended to define your favorite layout yourself. To define your own keymap create file named keymap_<name>.c and see keymap document(you can find in top README.md) and existent keymap files.
