    PWM Pin Output ( high voltage )

    rcnmartell

      is there a way to change the stop output voltage of the PWM pin I am using ( GPIO_11  ) .  I am trying to create pulses at a specific frequency but the pin when stoped ( timer disable )  sets to 3.3V.. I want to be able to have to go to zero V.

       

      I have tried changing the OC polarity to Low but that did not work  .Changing the duty cycle and not stopping the PCM timer does not produce good results.

      thanks
