X-NUCLEO-NFC04A1 dynamic NFC/RFID tag IC expansion board Firmware Package

Introduction

This firmware package includes Components Device Drivers, Board Support Package and example applications for STMicroelectronics X-NUCLEO-NFC04A1 dynamic NFC/RFID tag IC expansion board.

Example Application

This program gives the User the possibility to read or write the tag of the X-NUCLEO-NFC04A1. The user needs an NFC enabled device as a smartphone that has to be at least 10 cm close to the antenna of the X-NUCLEO-NFC04A1. The LEDs indicate the operational mode:

  • LED1 is on: by reading the tag the User obtains the parameters of the WiFi access points.
  • LED2 is on: by reading the tag the User is redirected to a website through the custom browser of the smartphone.
  • LED3 is on: the User can overwrite the value of the tag through the use of any NFC application.

Tested Platforms

This firmware has been tested on STM32 NUCLEO-F401RE
