Hello, I'm using a nucle 411 to test a RC servo driver. Si I configure 4 TIM3 channel to output PWM signal. Everithing is Ok, except that I can't finde a function to change PWM Duty Cycle.

Is there any?

    try 

    __HAL_TIM_SET_COMPARE(htim, tim_channel, cnt);

    where cnt is the new pulse interval. cnt /htim->Init.Period would be theduty cycle.
