Adding additional ADC

[wesee]

I have followed this tutorial (https://devzone.nordicsemi.com/nordic/nrf-connect-sdk-guides/b/getting-started/posts/nrf-connect-sdk-tutorial---part-2-ncs-v1-4-0#h185sjwm5882m1bcimiad82dnf4kcy0b) and it was working.

But I want to add additional 2 ADC.  I have tried a few configurations and they all didn't work.  

anyone can help?

Hello,

But I want to add additional 2 ADC.

By this, you mean that you would like to use a total of 3 SAADC channels, is that correct?
If so, you will have to setup and configure additional channels, you can see this demonstrated in this example.

Then all that remains is to trigger the sampling on the channels, however you intend for that to happen. For starters, you can set it up to sample both channels as part of the periodic adc_sample_event from the NCS SDK tutorial you linked in your ticket, and when you have that working you can proceed to make the sampling happen according to the requirements of your application.

If this is not what you meant to ask for, please elaborate.

I have tried a few configurations and they all didn't work. 

Please elaborate - what have you tried, and what did you observe? The more details you provide, the easier it is for us to help you.

Best regards,
Karl
