Hello, I have works on triple ADC conversion using DMA and it works, but I don't understand why I have some misalignment. I use STM32F4-Discovery borad.
ADC config is :
ADC1 :            ADC2:                ADC3:
    Channel 1        Channel 6            Channel 10
    Channel 3        Channel 8            Channel 12
    Channel 5        Channel 9            Channel 13

So I should have array :
Channel 1 - Channel  6 - Channel 10 - Channel 3 ...
As I use a array[9] all channel shoul have the same position at each time but thay move ...
Can someone help me or explain me how to check the good channel in the array?

NB : my code is linked.
