NFC EEPROM sample application

NFC EEPROM Application based on X-NUCLEO-NFC04A1 expansion board

The application will write an URL to the EEPROM of the NFC tag on your board. This will be able to be read by any NFC device capable of reading NFC tags.

The example uses the EEPROM driver provided for the X-NUCLEO-NFC04A1 expansion board based on the ST25DV04K dynamic NFC/RFID tag.
