I have setup ADC1 & ADC2 for dual mode sampling in CubeMX for the Nucleo-H743ZI, when I change the input channel for ADC2 then Cube sets the "DMA Access Mode" to disabled for both channels. Is this normal behavior?

Hi @Wde G.1​ 

Thanks for the feedback,

It is a normal behavior :

when we change the input (for example IN9 to ===> IN6), DMA ACCESS MODE still enabled.

When we unchecked IN9 for example then check IN6, DMA access mode change to Disable and to enable it you should go to ADC1 and change it to enable.

Best regards,

Thank you Nesrine!

If it's normal behavior then it ok once you know it ;)
