ADC function on nrf52 with version 1.8.0

[Mo Chen <sh...@gmail.com>]

Hi all,

Since the 1.8.0 adopted a new version of the nrfx driver. The old ADC code
is not working.

I wonder if there is a tested working ADC example available for nrf52 with
version 1.8.0?

I have been working on this for almost two weeks to get it work but with no
success. The ADC always gives a value of 0.

Can anyone help update the example code in the tutorial on the official
website https://mynewt.apache.org/latest/tutorials/sensors/nrf52_adc.html

Or share a working code with me?

<https://mynewt.apache.org/latest/tutorials/sensors/nrf52_adc.html>Regarding
nrf52 adc, my specific question is: in the following configuration
structure, what should I input for cc.pin ? I input NRF_SAADC_INPUT_AIN1,
but it won't work.

struct adc_chan_cfg cc = {
.pin = NRF_SAADC_INPUT_AIN1,
.differential = false,
.pin_negative = NRF_SAADC_INPUT_DISABLED,
.gain = ADC_GAIN1_6,
.reference = ADC_REFERENCE_INTERNAL
};

Thank you very much!
