Hello,I am quite new to STM32, so I would highly appreciate your help.I am using an STM32F407G-DISC1 board.I am trying to generale phase shifted complementary PWM for PFSB control. I am using TIM1 CH1/1N to generate one pair of signals, and TIM8 CH2/...

I did some reading in the reference manual and I think I managed to make it work! Instead of changing CCR value, I change the CNT value of TIM8 and drive it in reset mode, triggered when TIM1 overflows. This synchronizes the the timers and allows to ...

Thanks again! I think I understand your explanation regarding TIM8_CR1.CEN - essentially TIM8 counter starts counting after the first trigger. I might have been changing TIM1->CCR2, but it didn't matter as TIM8 was not restarting. Now, I understand t...

Oh and apologies, just noticed your PS! Will change Channel 2 to Compare Output Ch2.

Hello,Thanks for replying! Below I describe the configuration of the key features for that function:TIM1Channel 2 set to Output Compare No Output. Trigger event is set by OC2REF. Channel 2 mode set to active level on match, to generate a trigger even...
