Hi,

Unfortunately no, Zerynth is third party which means that we don't offer any support for it. I think it would be better to direct your question to the Zerynth forum here.

Hi Jared, it's not possible to access to this pin with the Python library in Zerynth, is it possible for you to verify ?

Hi,

You can use this pin as any other analog pin. The reason that the analog pin is at that specific connector is to make the DK compatible with Arduino shields.

Hi,

On page 16 ( figure 10 ) of the nRF52 DK User guide you can see that the connector P2 has only 6 Analog inputs, referenced A0 to A5 and no P0.02 !

This pin P0.02 is on the P4 connector and have the référence AREF ( figure 11, page 17 ).

So my question is how to use this pin as an Analog input and if yes what's it reference A?

Thank in advance for your reply

Hi,

I'm not sure I understand your question. P0.02 is listed as General purpose I/O/SAADC/COMP/LPCOMP input which means that it can either function as a normal GPIO or as an analog pin.
