PWM frequency

Post by kath2 » Sat Apr 02, 2016 4:35 am

Is there a way I can change the PWM frequency on the Rephone? I need to drive a sail servo motor and it really does not like the frequency used by default - not sure what that frequency is, either.

Can't run it of a Xadow Duino because I need those pins to run LEDs.

I'm guessing this isn't possible then?

Probably possible. I haven't personally calculated, but the prescaler should provide you the 50Hz. The duty cycle will be a little rough.
