Trying to detect the NFC tap

[NASOK.1]

I am trying to detect the NFC tap and try to raise a flag whenever a flag is seen and to do the same function each time.is there any example available?I am able to read and write to EEPROM but I don't get any idea how to detect a tap

Hi @NASOK.1 ,

Please have a look at GPO feature in ST25DV datasheet available there : https://www.st.com/en/nfc/st25dv64kc.html

the RF_ACTIVITY or FIELD_CHANGE mode can help you to fit with your needs. at a tap you will be able to get a flag on GPO output.

I hope this helps,

Best Regards,

BB
