RFID1356MIFARE with ESP32 over UART = possible ?

[GeorgeFlorian1]

Hello.

I am interested in integrating the RFID1356MIFARE with the ESP32-EVB an using it as a card reader.

The first step was to connect the RFID to an USB hub using a mini-USB cable and selecting UART mode (both LEDs blinking at the same time).

The second step was to disconnect it from USB and connect it to the ESP32 using the included UEXT ribbon.

Next I uploaded the following code to the ESP:

Code: Select all

PN532_HSU pn532hsu(Serial1);
PN532 nfc(pn532hsu);

void setup() {
  enableCore1WDT();
  delay(100);
  Serial.begin(115200);

  nfc.begin();
  delay(100);

    uint32_t versiondata = nfc.getFirmwareVersion();
  if (! versiondata) {
    Serial.print("Didn't find PN53x board");
    // while (1) delay(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);
  
  // configure board to read RFID tags
  nfc.SAMConfig();
  
  Serial.println("Waiting for an ISO14443A Card ...");
  
// ...
}

void loop()
{
  delay(1);

  uint8_t 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, &uidLength);
  
  if (success) {
    // Display some basic information about the card
    Serial.println("Found an ISO14443A card");
    Serial.print("  UID Length: ");Serial.print(uidLength, DEC);Serial.println(" bytes");
    Serial.print("  UID Value: ");
    nfc.PrintHex(uid, uidLength);
    Serial.println("");
    
    if (uidLength == 4)
    {
      // We probably have a Mifare Classic card ... 
      Serial.println("Seems to be a Mifare Classic card (4 byte UID)");
	  
      // Now we need to try to authenticate it for read/write access
      // Try with the factory default KeyA: 0xFF 0xFF 0xFF 0xFF 0xFF 0xFF
      Serial.println("Trying to authenticate block 4 with default KEYA value");
      uint8_t keya[6] = { 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF };
	  
	  // Start with block 4 (the first block of sector 1) since sector 0
	  // contains the manufacturer data and it's probably better just
	  // to leave it alone unless you know what you're doing
      success = nfc.mifareclassic_AuthenticateBlock(uid, uidLength, 4, 0, keya);
	  
      if (success)
      {
        Serial.println("Sector 1 (Blocks 4..7) has been authenticated");
        uint8_t data[16];
		
        // If you want to write something to block 4 to test with, uncomment
		// the following line and this text should be read back in a minute
        // data = { 'a', 'd', 'a', 'f', 'r', 'u', 'i', 't', '.', 'c', 'o', 'm', 0, 0, 0, 0};
        // success = nfc.mifareclassic_WriteDataBlock (4, data);

        // Try to read the contents of block 4
        success = nfc.mifareclassic_ReadDataBlock(4, data);
		
        if (success)
        {
          // Data seems to have been read ... spit it out
          Serial.println("Reading Block 4:");
          nfc.PrintHexChar(data, 16);
          Serial.println("");
		  
          // Wait a bit before reading the card again
          delay(1000);
        }
        else
        {
          Serial.println("Ooops ... unable to read the requested block.  Try another key?");
        }
      }
      else
      {
        Serial.println("Ooops ... authentication failed: Try another key?");
      }
    }
    
    if (uidLength == 7)
    {
      // We probably have a Mifare Ultralight card ...
      Serial.println("Seems to be a Mifare Ultralight tag (7 byte UID)");
	  
      // Try to read the first general-purpose user page (#4)
      Serial.println("Reading page 4");
      uint8_t data[32];
      success = nfc.mifareultralight_ReadPage (4, data);
      if (success)
      {
        // Data seems to have been read ... spit it out
        nfc.PrintHexChar(data, 4);
        Serial.println("");
		
        // Wait a bit before reading the card again
        delay(1000);
      }
      else
      {
        Serial.println("Ooops ... unable to read the requested page!?");
      }
    }
  }
}

The above code uses https://github.com/elechouse/PN532 library.

Inside it I've modified:

Code: Select all

void PN532_HSU::begin()
{
    _serial->begin(38400, SERIAL_8N1, 36, 4);
}

If I want to get a read I connect the 3.3V_UEXT_E jumper.

The code above returns only "Didn't find PN53x board".

If I change the code to a simple Serial read:

Code: Select all

if(Serial1.available()) {
  Serial.print(Serial1.read());
  Serial.print(" ");
}

I get some random characters each time I connect the jumper, even when I don't have a card in front of the reader:

Code: Select all

And when I put a card in front of the reader I get a normalized sequence. But I don't know where it starts or where it ends.

Is there anybody who made something similar ?

Thank you.
