Quick n dirty HPWM out of phase

[keithdoxey]

Assuming a PIC with at least 2 PWM channels, can someone suggest a quick way to output two PWMs exactly 180 degrees out of phase with each other?

How about a PIC with a Comparator. Feed the PWM into comparator and use the comparator output to give your out of phase signal.

Advantages...

No external components
no software overhead other than setting up comparator

Disadvantages...

You lose one comparator and a few pins on your PIC
