Hello,

I have made a test to check and I don’t have any problem.

I succeeded to read 4 analog inputs by ADC using DMA:

I used: PA0 ------> ADC1_IN0

            PA1 ------> ADC1_IN1

            PA2 ------> ADC1_IN2

            PA3  ------> ADC1_IN3

You will find attached my file main. c

& I already resolve that problem,
