As a relative newbie to Nordic, configuring the nrf52 saadc to behave like the nrf51 code above was requiring more reading than I have time for at the moment, but I stumbled upon the eddystone library and used es_battery_voltage_get() from there, which seems to have done the trick.

Thanks guys for the replies. After looking closer, I see what you mean that the problem is not a difference in sdk, but instead a difference in platform. I was in a hurry and when it didn't compile I jumped to the conclusion that it was very different, but after looking closer maybe it's not so different. The code above works on the nrf51 and uses NRF_ADC_Type to configure the ADC, but I need it to work on the nrf52 where NRF_SAADC_Type is used. So perhaps I just need to port the settings over to NRF_SAADC_Type. I'll give this a shot and post my code if it works.

That is correct. What you are using in the snippet above is not SDK dependent, so it should be the same in SDK14. Have you tested it? Did it not work?

BR,

It looks like you're accessing the peripherals directly, so, not using the SDK, but only the MDK. That would mean this code would run without any adjustments.
