## MicroPython - PN532 NFC/RFID DRIVER (SPI)

MicroPython SPI driver for the [PN532 NFC/RFID Breakout](https://www.adafruit.com/product/364) and [PN532 NFC/RFID Shield](https://www.adafruit.com/product/789) (port from [CircuitPython driver](https://github.com/adafruit/Adafruit_CircuitPython_PN532) )

### Example:

```

import NFC_PN532 as nfc

from machine import Pin, SPI

# SPI

spi_dev = SPI(1, baudrate=1000000)

cs = Pin(5, Pin.OUT)

cs.on()

# SENSOR INIT

pn532 = nfc.PN532(spi_dev,cs)

ic, ver, rev, support = pn532.get_firmware_version()

print('Found PN532 with firmware version: {0}.{1}'.format(ver, rev))

# Configure PN532 to communicate with MiFare cards

pn532.SAM_configuration()

# FUNCTION TO READ 

def read_nfc(dev, tmot):

    """Accepts a device and a timeout in millisecs """

    print('Reading...')

    uid = dev.read_passive_target(timeout=tmot)

    if uid is None:

        print('CARD NOT FOUND')

    else:

        numbers = [i for i in uid]

        string_ID = '{}-{}-{}-{}'.format(*numbers)

        print('Found card with UID:', [hex(i) for i in uid])

        print('Number_id: {}'.format(string_ID))

read_nfc(pn532, 500)

Reading...

Found card with UID: ['0x0', '0xa', '0x33', '0xc0']

Number_id: 0-10-51-192

```
