## Prerequisites

This library depends upon a modified version of the **Adafruit_PN532** library which you can obtain from this GitHub Repository.

https://github.com/BrightSoul/Adafruit-PN532

You must install the Adafruit_PN532 and cie_PN532 in your Arduino _libraries_ directory.

Plese follow the instructions from the Arduino guide.

https://www.arduino.cc/en/Guide/Libraries

## Wiring PN532 breakout to the Arduino Uno for SPI communication

At present, just the SPI connection is supported. The examples provided will work with this wiring.

![images/pn532-wiring-spi.png](images/pn532-wiring-spi.png)

This wiring is also described in detail on this page at the Adafruit website.

https://learn.adafruit.com/adafruit-pn532-rfid-nfc/breakout-wiring

## Getting started

Create a new arduino project and set it up like this:

```C++

//Include some libraries

#include 

#include 

#include 

//Use the cie_PN532 with the typical wiring, as pointed out above

cie_PN532 cie();

void setup(void) {

  #ifndef ESP8266

    while (!Serial); // for Leonardo/Micro/Zero

  #endif

  Serial.begin(115200);

  //Initialize the PN532 breakout board

  cie.begin();

}

```

Then, in your loop, wait for a card then read its ID_Servizi (a low-security unique identifier)

```C++

void loop(void) {

  //Let's see if a card is present

  bool cardDetected = cie.detectCard();

  if (!cardDetected) {

    //No card present, we wait for one

    delay(100);

    return;

  }

  //Good! A card is present, let's read the ID!

  word bufferLength = EF_ID_SERVIZI_LENGTH;

  byte buffer[EF_ID_SERVIZI_LENGTH];

  if (!cie.read_EF_ID_Servizi(buffer, &bufferLength)) {

    Serial.print(F("Error reading EF.ID_SERVIZI"));

    delay(1000);

    return;

  }

  //We were able to read the ID_Servizi, print it out!

  Serial.print(F("EF.ID_Servizi: "));

  cie.printHex(buffer, bufferLength);

}

```

## More examples

This library comes with an _examples_ directory. You can load and run examples from the Arduino IDE by clicking the File menu -> Examples -> cie 532.
