I want to print out 5 waveforms in 1us time.

I want to print out 5 waveforms during 1us.So, I printed out 5 MHz period PWM from TIM3.We tried to change the duty cycle of TIM3 to zero at interrupt time by running a 1 MHz timer counter on TIM6. However, it was confirmed that TIM6's 1 MHz timer co...

Resolved! "DMA is not working on STM32H7 devices" article is wrong

I think the article here:https://community.st.com/s/article/FAQ-DMA-is-not-working-on-STM32H7-devicesis wrong. In solution 3 it invalidate D-cache before reception. This doesn't make sense, it has to invalidate the D-cache after reception.
