Connection
----------
In case of using ATMega32U4(Teensy2.0):
1. Supply power with VCC and GND.
2. Connect CLOCK to PD1 and DATA to PD2. You can change pin with config.h.
3. Optionally you may need pull-up register. 1KOhm probably work.

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.
