Crate pc_keyboard

Driver for a PS/2 keyboard.

Supports PS/2 Scan Code Set 1 and 2, on both UK and UK English keyboards. See the OSDev Wiki.

Requires that you sample a pin in an interrupt routine and shift in the bit. We don’t sample the pin in this library, as that makes testing difficult, and it means you have to make this object a global static mut that the interrupt can access, which is unsafe.
