## Credits
TMK itself is written by hasu, original sources [here](https://github.com/tmk/tmk_keyboard).
The USB support for Kinetis MCUs is due to RedoX. His ChibiOS fork is also [on github](https://github.com/RedoXyde/ChibiOS); but it doesn't include Teensy LC definitions.
## Features that are not implemented yet
