SPWM_INT - Multiple Software PWM Question

You may need to limit the decrement counter so that it never goes below 0

Code:

If DutyVar3 > 0 then
    DutyVar3 = DutyVar3 -1
else
    DutyVar3 = 0
endif

Ah! You think DutyVar3 is ending with -1? I can hook up my serial LCD and see for sure, but that looks to be what's happening. Thanks Barry!

That was it. I should have learned by now to go over my loop code in more detail.

Any ideas on combining SPWM and blinking LEDs?
