ADC calibration by using Calibration Averaging method

Venu_M — Fri, 01 Sep 2023 16:21:03 GMT

Hello NXP team,

I want to do calibrate the ADC results by using Adc_Calibrate(), I can able to do the 32samples only, not able to change the any other samples .

If i want to change the sample count from 32 to 16 or 8 , whether i need to change the bit position manually in the Adc_Sar_Ip.c?

As far as I know ADC performance specifications are guaranteed when calibration uses maximum averaging i.e. when AVGEN = 1 and AVGS = 3. This is why Adc_Calibrate uses 32 samples. It is not recommended to modify the NRSMPL.

Best Regards,
Robin
