12f629 freq divider?

[Darrel Taylor]

I thought there was only 24 bytes ram on a '675.

64, but it won't matter much.
SSPWM uses ASM interrupts. So the issue of saving all the PBP system vars doesn't apply.

A comment in the sspwm.inc file would fix that.

Or maybe a note to use the current version.

That's what I get when I get my 10Fxxx's and 12Fxxx's corn-fuzzed...

Well then that's the one I'm going to play with some more...

Ski, if you get the 24-bit stuff, here is a what a PIC24 will do in this kind of situation:

1. Hardware PWM from 30Hz to 500KHz+.
2. Up to 16-bit duty cycle resolution at lower frequencies.
3. Up to 5 independent hardware PWM's.
4. 0% processor overhead.
5. Virtually no coding - except to set up registers.

All this from a single $2, 28-pin device.
