That would be this thread:
Probably the best thing would be if I add a blade type for servos that handles all the underlying stuff, and prints out warnings or something if you try to use it in a way that wouldn’t work.
For your case, how many servos do you need to control?
One complication I just noticed is that TIM15 (which would be ideal for controlling two servos) is used to synchronize the PWM across timers, and that doesn’t work if TIM15 is running at a different frequency.
