Hi Simon,

Thanks for that recommendation.
I actually had some issue with 2 sensors, and that solved the issue. 👍

Hi,

Reuven has a good suggestion here. Additionally, I'd recommend making sure that you have set the pins P0.09 and P0.10 as regular GPIOs by using devicetree to configure NFCT pins as GPIOS like this: &uicr { nfct-pins-as-gpios; };

I see you're using these as GPIOs in your overlay file.

Best regards,

Simon

Hi,

Look at this macro, this should do the work along with macro concat for the name (you may need to wrap the struct dev into struct)

STRUCT_SECTION_FOREACH
