NFC library for Arduino

This is an Arduino library for PN532 to use NFC technology.
It works with

• NFC Shield
• Xadow NFC
• PN532 NFC/RFID controller breakout board

Features

• Support I2C, SPI and HSU of PN532
• Read/write Mifare Classic Card
• Works with Don's NDEF Library
• Support Peer to Peer communication(exchange data with android 4.0+)
• Support mbed platform

Getting Started

1. Download zip file and
   extract the 4 folders(PN532, PN532_SPI, PN532_I2C and PN532_HSU) into Arduino's libraries.
2. Downlaod Don's NDEF library and extract it intro Arduino's libraries.
3. Follow the examples of the two libraries.

To do

• Card emulation

Contribution

It's based on Adafruit_NFCShield_I2C.
Seeed Studio adds SPI interface and peer to peer communication support.
@Don writes the NDEF library to make it more easy to use.
@JiapengLi adds HSU interface.
