NFC Read

This example illustrates the use of NFC Read

import android.content.Intent;
import android.os.Bundle;


import ketai.net.nfc.*;

String textRead = "";
KetaiNFC ketaiNFC;

void setup()
{   
  orientation(LANDSCAPE);
  textAlign(CENTER, CENTER);
  textSize(36);
}

void draw()
{
  background(78, 93, 75);
  text("Last tag read:\n"+ textRead, width/2, height/2);
  text("<Touch tag to read>", width/2, height-35);
}

void onNFCEvent(String txt)
{
  textRead = txt;
}


//set our write string....
void mousePressed()
{
  ketaiNFC.write("" + millis());
}


//Press any key to cancel write
void keyPressed()
{
  ketaiNFC.cancelWrite();
}

/*
  The following code allows the sketch to handle all NFC events
 when it is running.  Eventually we would like to handle this
 in a more elegant manner for now cut'n'paste will suffice.
