is this too obvious for a post?
I recently realized something blindingly obvious that I'd overlooked for a few years - that I can generate a servicable PWM triangle wave from a micro by using two PWM outputs with timers set to slightly different frequency. (i.e. no processor load whatsoever, no analog circuitry other than the filter). Is this worth sharing here in some form?
