Hi all.

This is my newest keyboard firmware / controller code.
Works on Teensy 4.0 with ILI9341 (320x240 color LCD). For any matrix keyboard (to PC USB). It has anti-ghosting.

Project description on my website (https://cryham.tuxfamily.org/portfolio/2020-k-c-4-controller/), with information about features and use cases (why I needed it, etc.).

Additionally: gallery (https://photos.google.com/share/AF1QipM8l6QF72fKF1OoLPfw0SpMIdAT3dv9tCnIVxrJHYfokQ Ip16S-GIml07b3A_trNA?key=Zy1DQnlsUXFTLW1rUjhlTGdFUGhMelh 3eVpjTTNn) with pictures and videos (https://www.youtube.com/watch?v=Qn8pUmFjvFI) (no voice though) on my channel (https://www.youtube.com/channel/UC9-gc9xgEeuSSKB8_dESLGw/videos).

Sources here (https://github.com/cryham/kc4), with info on used libraries.

K.C.4 is an upgrade from my previous K.C. (https://cryham.tuxfamily.org/portfolio/2018-k-c-controller/) for Teensy 3.2.
It allows changing any key mappings (on layers) or editing sequences on display, in real-time.
It also features few fullscreen demos like Plasma, rotating 3D polyhedrons etc. There is a game on it too.

The keyboards aren't made by me, just quite modified. They have reduced (cut off) rubber domes, making them much softer and nicer to use.
