Nothing yet. Procrastinating...
PIC18F2620 with 2 digital outputs. I have them wired up on an old
These ports can be used for TRIG inputs. Additionally they can be
analog in, measuring cap voltage.
Alternatively, RB4-RB7 have interrupt on change, giving one interrupt
when one of the 4 changed. These have to be distributed between the
oscillator feedback and envelope feedback.
From changed requirements the TRIG/DISCH pin needs to serve as an
