K-Type RGB Matrix Keymap

This is an experimental keymap adding support for RGB Matrix on the K-Type.

The keyboard should now support full RGB lightings. The lighting animations are running at 10 fps for performance reasons. You can configure this by changing the RGB_MATRIX_LED_FLUSH_LIMIT inside the config.h file to a lower value. For example RGB_MATRIX_LED_FLUSH_LIMIT 16 would mean that the animations run every 16 ms or at 60 fps.
