NUCLEO-C071RB Example with X-NUCLEO-NFC12A1 not working

Bassem · ‎2026-05-02

Dear ST colleagues,

I tried recently the package X-CUBE-NFC12.

First I tested on NUCLEO-L476RG board the delivered example and it was working out of the box, then I tried on NUCLEO-C071RB but it was not working, first I noticed that the Pins configuration are not correct it was fixed, but still not working, did anyone ever test this example, because I assume it needs to work without any modification.

Thank you in advance for your support.

Best regards

Bassem Taamallah

Hi,

I guess this is due to the polarity of the user button on NUCLEO-C071RB vs. NUCLEO-L476RG (active high vs. active low)
