nrf52810 SAADC sample code is not giving proper values

[Vimalnath]

Hi,

I am using nrf52810 and a sample SAADC code from the examples folder provided by the manufacturer. I have connected a potentiometer for validating my output values. I have kept the potentiometer to a constant voltage level and tried to read the ADC values, but the values keeps changing every time I try to read it. I have also tried with nrf_drv_saadc_sample() function (without using PPI), still the output was same.

by how much?

all real-world signals are subject to noise - so it is unrealistic to expect that the ADC output will remain dead constant.

Thanks for the reply. Yes what you sad is correct. I have figured out the issue, I was testing the adc at the wrong pin.
