attiny85 keyboard rev-01

Basic attiny85-based micro-USB based keyboard, uses a single MX Cherry-style mechanical keyboard switch.

Code, etc at https://github.com/softplus/random/tree/master/attiny85_keypad

Note: These don't actually work. Using ATTINY85 for USB keyboards is totally hit & miss. You need to use a hub to get the USB close, and even that doesn't help much.
