Hi Joe

Your observation seems to confirm what I'm saying. All software timed processes like Serout or Pulsout are affected by interrupts biting into their timing. I have had this experience before with regards to Serin and Serout. HPWM is a hardware timed process as is HSERIN or HSEROUT which work with devices that have the relevant hardware built in. Unfortunately, there is no HPULSIN or HPULSOUT in PbP.

I haven't used servos at all
