3 channel ADC interrupt

Hello guys,
I’m trying to get real-time data from a 3 channel accelerometer using interrupt.
I have no problem when I work with 1 channel without interrup, but when it comes to getting data from 3 channels simultaneously, I can’t get the data.
What should I do?!
Thanks.

Is this about how to do ADC’s end of conversion/sequence interrupt? Or is it how to read ADC channels in a GPIO interrupt handler or something? Do you want to share your code?
