Capacitive Discharge Welder Pt II

Cap Discharge Micro Re-work

Here is the state of the hardware mods on the micro so far:

  1. Encoder has be re-routed to pins 1  and 32 (int 0 and 1) to allow the encoder to be handled with an IRQ handler- no traces cut for this mod
  2. Display clock routed to pin 2 (PD4) to allow access to OC1A
  3. OC1A routed to the Cap discharge trigger. This lets us use timer1 for high resolution timing of the discharge pulse
  4. 10K resistor on the ISP +5V shorted
