Problems using ADC (with DMA) in stm32H7 boards

[LColq.1]

Hi,

I'm trying to perform analog-to-digital conversion using the DMA function on dual-core STM32H7 board series. Basically, I can not make it work. I have tried with other STM32 boards (like STM32L476RG for instance) successfully but it seems that the settings for the STM32H745 board to perform ADC are kind of different. Could anyone help me with some guidance on how to set the STM32H745ZI-Q board to perform Analog-to Digital conversion using DMA function?

Kindest regards,

Luis

Elaborate.

Proceeed step by step: get ADC polled working, then move on to DMA. You may also want to learn simple DMA first, e.g. timer-triggered, perhaps one of those examples where DMA is used to change PWM duty of the timer which triggers that DMA.
