How to use PN532 NFC module?

For using PN532 module, first we will choose the mode of communication between MODULE and CONTROLLER. As mentioned earlier this module has three interfaces, of which we have to choose one. Remember at any given point of time only one of three interfaces can be used. All three cannot be used together. We will have to choose the mode of interface using two switches solder to the board. The switches are S1 and S2 shown in pin diagram.

S1	S2	Interface
OFF	OFF	HSU (High Speed UART)
ON	OFF	I2C
ON	ON	SPI

Choose the mode of interface and corresponding state of switches from above table. Next toggle the switches S1 and S2 to those positions.

After choosing the type of interface, connect the module to the controller or processor. Say if you opted to use I2C, then connect module to I2C of the controller. If you opted to use SPI, then connect module to SPI of controller.

After interfacing you have to download the library files for the module from corresponding websites. Say for ARDUINO platform [https://www.arduinolibraries.info/libraries/adafruit-pn532]. Save the library files in the IDE program files.

Now all that left is to write the program for the controller or ARDUINO in the IDE software. And do call up on the saved library files while writing the program. With those libraries we can directly communicate with the module while skipping all the steps of communication protocol.

Once the programming is done, power up the circuit to get the desired response.

Applications:

Media or Data sharing

Robotics

Smart Phones and Smart devices

Security systems

Computer Peripherals

Package Identification

Theft protection systems

This example will wait for any ISO14443A card or tag, and

If the card has a 4-byte UID it is probably a Mifare

Classic card, and the following steps are taken:

- Authenticate block 4 (the first block of Sector 1) using

the default KEYA of 0XFF 0XFF 0XFF 0XFF 0XFF 0XFF

Arduino Library

Installatie van Arduino IDE libraries: Arduino info

NFC library for Arduino

This is an Arduino library for PN532 to use NFC technology. It’s based on Adafruit_NFCShield_I2C , improved by Seeed Studio, added HSU(High Speed Uart) driver by Elechouse.

Features

Support all interfaces of PN532 (I2C, SPI, HSU )
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

Download zip file and extract the three folders(PN532, PN532_SPI, PN532_HSU and PN532_I2C) into libraries of Arduino.
Downlaod Don’s NDEF library and extract it into libraries of Arduino’s into a new folder called “NDEF” (Note if you leave this folder as NDEF-Master Arduino will not be able to use it as a library)
Follow the examples of the PN532 library

To do

Card emulation

HSU Interface

HSU is short for High Speed Uart. HSU interface needs only 4 wires to connect PN532 with Arduino, Sensor Shield can make it more easier. For some Arduino boards like Leonardo, DUE, Mega ect, there are more than one Serial on these boards, so we can use this additional Serial to control PN532, HSU uses 115200 baud rate .

To use the Serial1 control PN532, refer to the code below.

#include <PN532_HSU.h>

#include <PN532.h>

PN532_HSU pn532hsu(Serial1);

PN532 nfc(pn532hsu);

void setup(void)

{

nfc.begin();

//...

}

If your Arduino has only one serial interface and you want to keep it for control or debugging with the Serial Monitor, you can use the SoftwareSerial library to control the PN532 by emulating a serial interface. Include PN532_SWHSU.h instead of PN532_HSU.h:

#include <SoftwareSerial.h>

#include <PN532_SWHSU.h>

#include <PN532.h>

SoftwareSerial SWSerial( 10, 11 ); // RX, TX

PN532_SWHSU pn532swhsu( SWSerial );

PN532 nfc( pn532swhsu );

void setup(void)

{

nfc.begin();

//...

}
