Forgive my ignorance, but aren't lower PWM frequencies easier to do? I know there is lots of code out there related to servo control running at ~60Hz - I'd think that you'd just have convert from a "built in" PWM philosophy to a manually-programmed PWM where you program discrete pulses at a given length?
