Split up `Keyboard` #30

Closed jonathanpallant closed 1 year ago

jonathanpallant commented 1 year ago

The struct Keyboard does three things:

Decodes PS/2 words into bytes, doing the parity check
Runs the Scan Code Set 1 or Scan Code Set 2 finite state machine to produce KeyEvents
Converts Key Events into Unicode according to the selected keyboard layout

These should be three objects:

Ps2Decoder
ScancodeProcessor<T> where T: ScancodeSet
EventProcessor<L> where L: Layout

This helps out the Neotron system, where these three objects live in different binaries (the BMC, the BIOS and the OS, respectively).
