No one denies the usefulness of DMA, but there are cases when it is unnecessary. Here we are talking about whether HAL provided the correct Multichannel operation without using DMA.
That's what I did in the end, i.e. configuring the desired channel(only one) before starting the conversion. it works.I will update my cube and hal library and try.Thanks all.
Does this issue still present? i have faced it too on stm32l476 stm32Cube 1.5.1 and seems like polling in MultiChannel single mode does not work properly.
