Mark maybe we can work this out together with Henrik's assistance. I went to the micro chip site and used their processor selector to find one that had the PWM built in. It looks like the 12F752 has what I need to try to get the HPWM to work. The datasheet says

• Capture, Compare, PWM (CCP) module:
- 16-bit Capture, max. resolution = 12.5 ns
- Compare, max. resolution = 200 ns
- 10-bit PWM, max. frequency = 20 kHz

Thats what I am looking for right? I've not read the rest of the datasheet. I picked this one out because I think I have one here already to start to work with.
Thanks
