RFID RC522 in Processing

pet0103

Hello,

I want to add the RFID RC522 Reader to my Processing sketch. I already have some buttons connected with my Arduino and thus I use Firmata to communicate between Arduino and Processing. I have not been able to use the RFID reader while using Firmata. The Arduino code for only the RFID reader is as the following:

// Example sketch to read the ID from an Addicore 13.56MHz RFID tag
// as found in the RFID AddiKit found at: 
// http://www.addicore.com/RFID-AddiKit-with-RC522-MIFARE-Module-RFID-Cards-p/126.htm

#include 
#include 

#define uchar   unsigned char
#define uint    unsigned int

//4 bytes tag serial number, the first 5 bytes for the checksum byte
uchar serNumA[5];

uchar fifobytes;
uchar fifoValue;

AddicoreRFID myRFID; // create AddicoreRFID object to control the RFID module

/////////////////////////////////////////////////////////////////////
//set the pins

const int chipSelectPin = 10;
const int NRSTPD = 5;

//Maximum length of the array
#define MAX_LEN 16

void setup() {                
  Serial.begin(9600);                        // RFID reader SOUT pin connected to Serial RX pin at 9600bps 

  // start the SPI library:
  SPI.begin();

  pinMode(chipSelectPin,OUTPUT);              // Set digital pin 10 as OUTPUT to connect it to the RFID /ENABLE pin 
  digitalWrite(chipSelectPin, LOW);         // Activate the RFID reader
  pinMode(NRSTPD,OUTPUT);                     // Set digital pin 10 , Not Reset and Power-down
  digitalWrite(NRSTPD, HIGH);

  myRFID.AddicoreRFID_Init();  
}

void loop()
{
  uchar i, tmp, checksum1;
  uchar status;
  uchar str[MAX_LEN];
  uchar RC_size;
  uchar blockAddr;  //Selection operation block address 0 to 63
  String mynum = "";

  str[1] = 0x4400;
  //Find tags, return tag type
  status = myRFID.AddicoreRFID_Request(PICC_REQIDL, str);   
  if (status == MI_OK)
  {
    //            Serial.println("RFID tag detected");
    //          Serial.print(str[0],BIN);
    //            Serial.print(" , ");
    //          Serial.print(str[1],BIN);
    //            Serial.println(" ");
  }

  //Anti-collision, return tag serial number 4 bytes
  status = myRFID.AddicoreRFID_Anticoll(str);
  if (status == MI_OK)
  {
    checksum1 = str[0] ^ str[1] ^ str[2] ^ str[3];
    //            Serial.println("The tag's number is  : ");
    //          //Serial.print(2);
    //          Serial.print(str[0]);
    //            Serial.print(" , ");
    //          Serial.print(str[1],BIN);
    //            Serial.print(" , ");
    //          Serial.print(str[2],BIN);
    //            Serial.print(" , ");
    //          Serial.print(str[3],BIN);
    //            Serial.print(" , ");
    //          Serial.print(str[4],BIN);
    //            Serial.print(" , ");
    //   Serial.println(checksum1,BIN);

    // Should really check all pairs, but for now we'll just use the first
    if(str[0] == 6)                      //You can change this to the first byte of your tag by finding the card's ID through the Serial Monitor
    {
     // Serial.print("CARD ONE");
      Serial.print(str[0]);

    } 
    else if(str[0] == 213) {             //You can change this to the first byte of your tag by finding the card's ID through the Serial Monitor
   //   Serial.print("CARD TWO");
      Serial.print(str[0]);

    }
    Serial.println();
    delay(1000);
  }

  myRFID.AddicoreRFID_Halt();          //Command tag into hibernation              

}

Is there any way that I can use this reader in Processing?
