I'm having a very tough time getting more than 1 channel of an ADC instance using DMA to work on the Nucleo-H753 board. No matter what I try, nada... After rigorous debug, found that the ADC is NOT even starting when I call it to right before my while(1) loop... It saying that there is an internal error (17) and fails to start. This leads me to think that there's a config issue/error on my end. Any tips on setting up multiple ADC channels using DMA on the STM32H7 line would be greatly appreciated, as they have the fancier/more finicky 16b ADCs
