NFC Write

This example illustrates the use of NFC Write

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

import ketai.net.nfc.*;

String writeStatus = "";
KetaiNFC ketaiNFC;

void setup()
{   
  orientation(LANDSCAPE);
  textAlign(CENTER, CENTER);
  textSize(36);
  String d = "Ketai writing tag at: " + month()+"/"+day()+"/"+year()+" "+hour()+":"+minute()+":"+second();
  ketaiNFC.write(d);
}

void draw()
{
  background(78, 93, 75);
  text("<Touch tag to write message>\nLast Write Status: "    + writeStatus, width/2, height/2);
  //  if (frameCount % (int)frameRate == 0)
  //  {
  //    println("setting write.");
  //    String d = "Ketai writing tag at: " + month()+"/"+day()+"/"+year()+" "+hour()+":"+minute()+":"+second();
  //    ketaiNFC.write(d);
  //  }
}

void mousePressed()
{
  println("setting write.");
  String d = "Ketai writing tag at: " + month()+"/"+day()+"/"+year()+" "+hour()+":"+minute()+":"+second();
  ketaiNFC.write(d);
  writeStatus = "";
}

void onNFCWrite(boolean result, String message)
{
  if (result)
    writeStatus = "SUCCESS writing tag!";
  else
    writeStatus = message;
}

//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.
