Contoh penerapan pn532 menggunakan platform micropyton pada board pn532

Kebutuhan perangkat

  • Reader NFC PN532
  • TAG NFC, bisa menggunakan kartu mifare
  • ESP32 controller

Rangkaian

Versi fritzing dapat Anda dapatkan di sini

Dari rangkaian di atas, mapping antara reader PN532 dan ESP32 adalah sebagai berikut

ESP32 PN532
5V VCC
GND GND
D18 (GPIO 18) SCK
D19 (GPIO 19) MISO
D23 (GPIO 23) MOSI
D5 (GPIO 5) SS

Contoh kode

import NFC_PN532 as nfc
from machine import Pin, SPI

# SPI
spi = SPI(1, baudrate=1000000, sck=Pin(18), mosi=Pin(23), miso=Pin(19))
cs = Pin(5, Pin.OUT)
cs.on()

# SENSOR INIT
pn532 = nfc.PN532(spi,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()

while True:
    print('Reading...')
    uid = pn532.read_passive_target(timeout=500)
    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))
