This is an Arduino library for PN532 to use NFC technology. It is for NFC Shield and Xadow NFC.

• Support I2C, SPI and HSU of PN532
• Read/write Mifare Classic Card
• Works with Don's NDEF Library
• Communicate with android 4.0+(Lists of devices supported)
• Support mbed platform
• Card emulation (NFC Type 4 tag)

• Easy way

  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.

• Git way (recommended)

  1. Get PN532 library and NDEF library

      cd {Arduino}\libraries  
      git init  
      git remote add origin https://github.com/Seeed-Studio/PN532.git  
      git pull origin master  
      git clone https://github.com/don/NDEF.git  
     

  2. Follow the examples of the two libraries

It's based on Adafruit_NFCShield_I2C. Seeed Studio rewrite the library to make it easy to support different interfaces and platforms. @Don writes the NDEF library to make it more easy to use. @JiapengLi adds HSU interface. @awieser adds card emulation function.
