X-NUCLEO-NFC02A1 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-NFC02A1 Dynamic NFC Tag Expansion Board based on M24LR.

Example Application

This is just a simple "hello world" style program for the X-NUCLEO-NFC02A1 Dynamic NFC Tag Expansion Board. The program writes a URI link to the M24LR dynamic tag using the synchronous programming model. It then reads back the URI from the tag to display it on terminal. The URI can also be retrieved from an NFC enabled smartphone/tablet.
