Czytnik PN532 podłączony do Arduino Uno daje błąd

Igus · Maj 6, 2024

Stworzyłem kod to formatowania taga RFID, niestety wyskakuje następujący błąd:

Unable to authenticate block 0 to enable card formatting!

Format failed.

Czy ktoś wie jak mógłbym ten problem rozwiązać?

Poniżej podsyłam kod którego używam:


#include <Wire.h>
#include <PN532_I2C.h>
#include <PN532.h>
#include <NfcAdapter.h>
PN532_I2C pn532_i2c(Wire);
NfcAdapter nfc = NfcAdapter(pn532_i2c);
String tagId = "None";
byte nuidPICC[4];
 
void setup(void) 
{
 Serial.begin(9600);
 Serial.println("System initialized");
 nfc.begin();
 formatNFC();
}
 
void loop() {
  formatNFC();
}

void writeNFC() {
  Serial.println("\nPlace a formatted Mifare Classic NFC tag on the reader.");
    if (nfc.tagPresent()) {
        NdefMessage message = NdefMessage();
        message.addUriRecord("http://arduino.cc");

        bool success = nfc.write(message);
        if (success) {
          Serial.println("Success. Try reading this tag with your phone.");        
        } else {
          Serial.println("Write failed.");
        }
    }
    delay(5000);
}

void formatNFC() {
    
    Serial.println("\nPlace an unformatted Mifare Classic tag on the reader.");
    if (nfc.tagPresent()) {

        bool success = nfc.format();
        if (success) {
          Serial.println("\nSuccess, tag formatted as NDEF.");
        } else {
          Serial.println("\nFormat failed.");
        }

    }
    delay(5000);
}

funkcję writeNFC() proszę ignorować, gdyż normalnie mam ją zakomentowaną

Interesuje mnie do czego służy ta zmienna. Z resztą czy nie powinieneś tam wpisać swojego tagu karty? Nie wiem czy dobrze podpowiadam.

Jak już mówiłem niektóre funkcje zignoruj bo pracuje nad nimi

To jest zmienna do zapisywania ID taga.

U mnie jest:
NfcAdapter nfc = NfcAdapter(pn532_i2c);

NfcAdapter nfc = NfcAdapter(pn532_i2c);
