X-NUCLEO-NFC05A1 NFC Card Reader Expansion Board Firmware Package

Introduction

This firmware package includes Components Device Drivers, Board Support Package and example applications for STMicroelectronics X-NUCLEO-NFC05A1 NFC Card Reader Expansion Board based on the ST25R3911B.

Example Application

This program gives the user the possibility to read the URI information written on the expansion board. The LEDs will blink for few seconds to indicate that the board is initializing. As soon as it finishes, the device is ready to communicate with external NFC devices. LED6 will blink until an NFC device is close to it and ready to read the URI value.

Tested Platforms

This firmware has been tested on STM32 NUCLEO-F401RE
