Hi,

The A0->A5 and D0->D13 pins on the DK refers to the Arduino shield standard, and not the analog pins(e.g. AIN1). See figure 2 here (Arduino signals routing on the nRF52 Development Kit board).

This is the Arduino shield standard:

Thanks guys,

I solved it as Sigurd said. But I think it is weird to the DK module says the P0.03 as A0. instead of P0.02

Cheers

Try the P0.02 pin instead. See this: nRF52832 Pin assignments.

Arepa,

I'm not sure why the nRF52 DK calls pin P0.03 A0 since its actually connected to AIN1 on the chip. That may be the issue you are having.

Can you attach your main.c file and I will take a look?

Cheers, Darren
