 Dear @RShar.9​ 

In order to activate ADC DMA on STM32H7 you need to follow these steps:

  • Activate ADC instance under analog ADC.
  • Add DMA under system core -> DMA and choose the ADC instance that you already activated.
  • Under ADC setting -> conversion data management setting choose DMA Circular mode.

Now you have configured ADC with DMA but you may have problem related to STM32H7 memory layout, so you will need to follow this article in order to get it working as expected.

Please use the last version of STM32CubeMX.

Hope that this solve your issue.

Best regards,

Houssem
