Generating a PWM that starts high, but ends low after N pulses have been completed. I have an Arduino Giga (STM32H7) and I'm using the timers to generate PWM's. Everything's working fine, programming is no problem, but I cannot come up with a way to implement what I want. I included a simple visual to describe what I want the output to look like. TIM1 is the master timer, it generates a PWM, set as active high (for CNT<CCR). I have a slave TIM8, which should do the following: when TIM1 starts over again/goes high, TIM8 should generate N pulses. The time it takes for N pulses to complete is shorter than the period of TIM1, I want them to retrigger each time TIM1 goes high again. Here's the catch: The pulses should immediately start high, however, once all the pulses have fired, the output should stay low.If it weren't for the last part, the solution would be simple: TIM1 uses UEV as output trigger, TIM8 takes an internal trigger input from TIM1, set TIM8 to One-Pulse Mode, set the repetition counter to N, and voila, you get bursts of N pulses on each TIM1 high
