Calculating average values of ADCs

Alexshea — Thu, 01 Sep 2022 19:11:01 GMT

@xiangjun_rong Hi, I tried what you said to calculate average values of adc channels, but when I use for loops, I don't receive any adc values. You told me to set #define TOTAL_AVERAGE_NUMBER 2, but even setting it 2 didn't help. I don't use adc interrupt in this code, since all the 8 adc channels are used and it seems that the for loops don't work either. Could you please once again check my code and help me resolve this issue.

Thanks in advance,

Alex

Hi,

Sorry for the delay.

I suggest you use interrupt mode to read ADC result instead of polling mode, the ADC polling mode wastes a lot of time for the core.

Hope it can help you

@xiangjun_rong Hi, thanks for the answer. Well, I've tried interrupt before, but I was able to work with only 2 ADCs and when I activated the third ADC the code stopped and locked and didn't execute. I didn't know what to do. I was wondering if you modify my code and add interrupt I can't work with interrupt while using all ADC channels myself
