SMB Alert on STM32F746NGH6TR

Hi,I'm trying to use a SMB alert on a STM32F746NGH6TR. Interestingly, the corresponding interrupt is not getting triggered. I already figured out that the interrupt works if I put the signal on PA9, but it doesn't work on PH9. I already checked for b...

DMA only working once

Good day,I'm trying to control this RGB leds N-PI55TATDatasheet I'm using an STM32H753VIT6To do that I have to create a fairly fast burst of data with pulses of 0.6, 0.3  and 0.9 us.To achieve this I set timer 7 to have an update even every 100nS the...
