I'm a beginner at STM8 programming. I'm designing a quad trailing-edge dimmer as my first STM8S003F3 project. I have a zero crossing pulse tied to a pin and generating an interrupt, and on this interrupt I want to trigger pulses on four output that e...

While doing bit-manipulation of timer registers during each particular timer event might technically work, I feel like it would be inviting a race condition. It also hardly qualifies as elegant -- it rather defeats the purpose of using the timer outp...

Thanks for replying, Cristian!That would have been too easy :)PWM mode 1 does not actually produce the behaviour I'm looking for.Here's what I'm seeing:

Okay, I found a workaround to get me past this issue. Rather than letting the timer control the output pins, I enable the output compare interrupt for all four capcom channels and set the output pins high myself. Then, I simply clear the output pins ...

TIM1 one-pulse PWM mode with four outputs -- I would like the pulses to start HIGH immediately when I enable the timer, so that they can go LOW individually at different times depending on each comparison.
