- ----------
- In case of using ATMega32U4(Teensy2.0):
-
- 1. Supply power with VCC and GND.
- 2. Connect CLOCK to PD1 and DATA to PD0. You can change pin with config.h.
- 3. Optionally you may need pull-up register. 1KOhm probably work.

- 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.
