ST / Mbed 2 deprecated HelloWorld_Async_NFC01A1

A simple application providing an example of asynchronous access to the X-NUCLEO_NFC01A1 Dynamic NFC Tag board.

Dependencies:   NDefLib X_NUCLEO_NFC01A1 mbed

Fork of HelloWord_Async_NFC01A1 by ST Expansion SW Team

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

The application provides a simple example of asynchronous access to the X-NUCLEO-NFC01A1 Dynamic NFC Tag Expansion Board. The program writes a URI link to the M24SR dynamic tag using the asynchronous programming model. The URI can then be retrieved from an NFC enabled smartphone/tablet.

A simpler example providing synchronous access to the tag is also available.
