i'm using RC522 RFID library with UTFT library in arduino mega 2560..
what i want is to print read value from RFID card on TFT as hex..

in my code it gives garbage characters on display..
please help!! :o

void setup()
{
  
   pinMode(13, OUTPUT);
 digitalWrite(13, LOW);

// Initial setup
  myGLCD.InitLCD();
  myGLCD.clrScr();
  
  myTouch.InitTouch();
  myTouch.setPrecision(PREC_HI);

  myGLCD.setFont(BigFont);
  myGLCD.setBackColor(0, 0, 255);
  
Serial.begin(9600); // Initialize serial communications with the PC
SPI.begin(); // Init SPI bus
RC522.init();
 
  
}

void loop()
{

   /* Temporary loop counter */

   byte i;
   
   /* Has a card been detected? */

   if (RC522.isCard())
   {
   /* If so then get its serial number */

   RC522.readCardSerial();
  
   
   /* Output the serial number to the UART */

   for(i = 0; i <= 4; i++)
   {
  
          myGLCD.setColor(255, 255, 255);
          myGLCD.print((char*)RC522.serNum[i], 350, 20);

   
   }

  
   }

Ok... i am not an expert, but it looks like you are printing to the same spot on the screen..
try adding something like this and see what happens.
" myGLCD.print((char*)RC522.serNum_, 350+(i10), 20); "_
_the (i10) may need adjusting to fit the font size.._
it may not be the best way but you get the idea..
