So to be clear, I cannot simply use PWM command of PIC BASIC PRO with 16C711? (I have 16C711 chips already). What if I use external RC as see in PBP manual? Still no PWM control? My programming skills don't include timer interrupt experience.

I have researched the MOSFET's and have found that FP30N06LE MOSFET N-CH LOG 60V 30A TO-220AB can be directly driven by logic level. I am going to put a simple resistor network to assure MOSFET remains off upon power-up. It also restricts the PIC output to a safe level. Still need an OptoIso?
