Can't help you at all with the HAL stuff, I wish you much luck.

I will observe that unless you configure the ADC's symmetrically the sequencing of the data is likely to give you a lot of headaches.

Which product are you using?

Do the execution get stuck at a given level?

Are the values in ADCs registers aligned with what you expect?

I don't know this HAL API but looking at the code you posted I see that:

1. You configured the ADC to use DMA.

2. You did not enable interrupts for the ADC.

So, how will an end of conversion event get triggered?

Who knows, it's a selective presentation of code, and HAL/Cube hide a lot of the detail, and has a different methodology.
