[sdiy] STM32 processor

[KD KD]

Nice board Eric!

I got one of these discovery boards for free last year, have not done
anything with it.

Just saw that ST have new part (F2) calming 120dmips! Plenty of memory
1M Flash, 256k Ram, should open for serious effects development i suppose.

I guess Collin F uses a STM for his new sequencer.
