keyboards (part 2)

[jscrane]

Now we have two classes of keyboard:

• raw, which drive "matrix" keyboards with ps/2 scancodes (PET, UK101)
• serial, which act like serial terminal inputs (Apple1, cpm80)

Each of these uses a different library combination: PS2KeyRaw and PS2KeyAdvanced / PS2KeyMap.

Raw has its own disadvantages too, it is tied to the UK variant of the PS/2 keyboard.

Could resolve the first problem by adding a scancode interface to PS2KeyAdvanced.

Stoffregen's PS2Keyboard provides APIs for scancodes and utf-8 characters so could be a potential solution. However it isn't clear how function keys are handled in the latter case.

Using a single library would allow to initialise it in hardware_init and be bound to by ps2_raw_kbd or ps2_serial_kbd as required.

It seems as if either PS2KeyAdvanced or PS2Keyboard would need to be forked to facilitate this though.
