Hi,

I want to run 2 adc simultaneously in conversion but it does not work with Imx7 phycore .
I succeded to function with one adc ,now I use the adc1_in3 and adc1_in2 with the configuration channel A for conversion 1 and channel B for conversion 2.Just my conversion 1 interruption work,i don't know the problem.
It is possible that there is a conflict between the two channels?

Thank you in advance 
Regards 
Antoine Viollet
