Did you configure the sensor as a RFID sensor?

Your code should resemble something like this:
#pragma config(Sensor, S1,     RFIDSNSR,            sensorI2CodatexRFID)
//*!!Code automatically generated by 'ROBOTC' configuration wizard               !!*//

task main () {
  while (true) {
    nxtDisplayCenteredBigTextLine(2, "%d", SensorValue[RFIDSNSR]);

Note that I don't have an RFID sensor, so I can't test this.

no that doesnt work. I tried. It just has a number counting up. My FTC team is going to try and develop a driver for it but all help is appreciated. For starters do you know of a website that explains I2C well and a tutorial on using it in robotc.

No tutorial, but I do know that the RFID sensor is extremely finicky and from what I hear from people who have programmed with it is that you'll have to fiddle a lot with it to make it work. It comes down to getting the timing right and all that fun stuff.

You might want to check out, perhaps there is some useful info there.
