Hello actionplus

actionplus >>Will these be enough? So, using PWM output from the PIC should be enough to drive the MOSFET. Will a FET do?<<

Yes it was enough...We used a 648A PWM... Got it working.. then attached a MOSFET to it, and ran a 12 volt model airplane motor and cycled the RPM's from 0 to 255 (255 being 100 percent). The Mosfet could handle 10 amps? and was about 1 dollar at the most... We only made one mistake... we accidently made a spark on one side of the circuit, and blew the PWM pin on the 648A...<chuckle> So use a Isolator when you are playing around with live ammo...We ended up using that 648A for other application that doesn't need that PWM port...<g>..

We also thought about using that same 648A chip for a LCD controller in 4 bit mode... Since the pin we blew was in the LSB of the LCD, and the LCD uses the MSB in 4 bit mode...We would assign the Data/Comand to pin B0, the Enable to B1, and ignore Pin B3 (our wonderful blownup PWM pin from our 12 volt sparky mistake <g>)
