[sdiy] MIDI commands to drive external clock steps..

[Roman Sowa]

With your programming skills this is half an hour job.

Real Time messages are the easiest to read, as they are all 1 byte long 
and don't care about any others, they can even appear in the middle of 
multi-byte messages without bothering anyone.
So configure UART for MIDI baudrate and look for 0xF8 - this is MIDI 
clock, which you can then feed to a divider of your choice and drive the 
pin. MIDI start is 0xFA, this can start your device outputing pulses. 
MIDI stop is 0xFC, use to to hold clocking. 0xFB - continue, so clock 
starts appearing again like it was on Pause. There's no Pause in MIDI, 
Stop is used for that.
