How to get dual synchronous ADC + DMA working on STM32H7 with NUCLEO-H723ZG board

FUnte.1 · ‎2023-04-27

Hello, I'm fairly new to working with STM32MCUs and looking for help to get dual synchronous ADC + DMA working on the H7.

I'm using the STM32CubeIDE with the graphic interface to configure my peripherals including ADC and DMA. I used this with the F7 line and was able to get it working but when I try this on the H7 line with a NUCLEO-H723ZG board it does not work and only shows zeros in the memory I dedicate for DMA use.

I read the DMA is not working on STM32H7 devices article but wasn't able to get it running. And I couldn't find a working example in the H7.

Could you kindly point me in the right direction to a working example or tutorials / information so I can figure out why my code is not working?

I don't like downloading source files - if I don't need them... 😉

Check if the DMA init in main is before ADC init.

And start with getting 1 ADC working.
