nRF Connect 2.0.0 ADC on nRF52840 DK emulating NRF52811

Hi everyone,  

Im porting a board from SciLabs to Nordic; since the NRF52811 is in stock I am using it via the nRF52840DK.

The included sample adc application doesn't seem to be compatible.  I tried a few examples on the internet and they did not work either.

I am new to Nordic and could use some pointers to how to get the saadc functioning in this setup.  Im not knowlegable enough yet to go off the docs here:  developer.nordicsemi.com/.../index.html

Thanks in advance!

Hi,

The sample needs an overlay file that looks like this:

/ {
	zephyr,user {
		/* adjust channel number according to pinmux in board.dts */
		io-channels = <&adc 0>, <&adc 1>;
	};
};

This will use AN0 and AN1 for the two channels.
