X-NUCLEO-NFC01A1 Dynamic NFC Tag Expansion Board Firmware Package

Introduction

This firmware package includes Components Device Drivers, Board Support Package and example applications for STMicroelectronics X-NUCLEO-NFC01A1 Dynamic NFC Tag Expansion Board based on M24SR.

Example Application

This is just a simple "hello world" style program for the X-NUCLEO-NFC01A1 Dynamic NFC Tag Expansion Board. The program writes a URI link to the M24SR dynamic tag using the synchronous programming model. The URI can then be retrieved from an NFC enabled smartphone/tablet.

A more complex example providing asynchronous access to the tag is also available.
