PN532 NFC RFID module V3 kits : Didn't find PN53x board



  • Hello

    I'm trying to make my PN532 NFC RFID module V3 kits working with my Arduino Uno.

    According to this manual to communicate with the Arduino in I2C mode I need to set the DIP switch like this :

    Channel 1: ON
    Channel 2: OFF
    

    Here is the wiring:
    Configuration Table

    Wiring

    I'v tried with this lib and the Adafruit one

    There is my code (it's the iso14443a_uid sketch)

    #if 0
      #include <SPI.h>
      #include <PN532_SPI.h>
      #include "PN532.h"
    
      PN532_SPI pn532spi(SPI, 10);
      PN532 nfc(pn532spi);
    #elif 0
      #include <PN532_HSU.h>
      #include <PN532.h>
          
      PN532_HSU pn532hsu(Serial1);
      PN532 nfc(pn532hsu);
    #else 
      #include <Wire.h>
      #include <PN532_I2C.h>
      #include <PN532.h>
      #include <NfcAdapter.h>
      
      PN532_I2C pn532i2c(Wire);
      PN532 nfc(pn532i2c);
    #endif
      
    void setup(void) {
      Serial.begin(115200);
      Serial.println("Hello!");
    
      nfc.begin();
    
      uint32_t versiondata = nfc.getFirmwareVersion();
      if (! versiondata) {
        Serial.print("Didn't find PN53x board");
        while (1); // halt
      }
      
      // Got ok data, print it out!
      Serial.print("Found chip PN5"); Serial.println((versiondata>>24) & 0xFF, HEX); 
      Serial.print("Firmware ver. "); Serial.print((versiondata>>16) & 0xFF, DEC); 
      Serial.print('.'); Serial.println((versiondata>>8) & 0xFF, DEC);
      
      // Set the max number of retry attempts to read from a card
      // This prevents us from waiting forever for a card, which is
      // the default behaviour of the PN532.
      nfc.setPassiveActivationRetries(0xFF);
      
      // configure board to read RFID tags
      nfc.SAMConfig();
        
      Serial.println("Waiting for an ISO14443A card");
    }
    
    void loop(void) {
      boolean success;
      uint8_t uid[] = { 0, 0, 0, 0, 0, 0, 0 };  // Buffer to store the returned UID
      uint8_t uidLength;                        // Length of the UID (4 or 7 bytes depending on ISO14443A card type)
      
      // Wait for an ISO14443A type cards (Mifare, etc.).  When one is found
      // 'uid' will be populated with the UID, and uidLength will indicate
      // if the uid is 4 bytes (Mifare Classic) or 7 bytes (Mifare Ultralight)
      success = nfc.readPassiveTargetID(PN532_MIFARE_ISO14443A, &uid[0], &uidLength);
      
      if (success) {
        Serial.println("Found a card!");
        Serial.print("UID Length: ");Serial.print(uidLength, DEC);Serial.println(" bytes");
        Serial.print("UID Value: ");
        for (uint8_t i=0; i < uidLength; i++) 
        {
          Serial.print(" 0x");Serial.print(uid[i], HEX); 
        }
        Serial.println("");
        // Wait 1 second before continuing
        delay(1000);
      }
      else
      {
        // PN532 probably timed out waiting for a card
        Serial.println("Timed out waiting for a card"
    [/code]);
      }
    }
    

    This is my output

    Hello!
    

    Thanks for help 🙂



  • In your sketch, remove everything above, and including #else and also the line #endif. You only need the I2C declarations in your case.

    Good luck!



  • Hi!

    I have the same problem. Did you resolve it?

    Thanks!
