Hi, I would lije to know if can anyone can helpme I'm trying to conect my xbee and procces the data using proccesin. I have a problem reading the incoming data. so far this is the code that I've written

// used for communication via xbee api
import processing.serial.*; 

// xbee api libraries available at http://code.google.com/p/xbee-api/
// Download the zip file, extract it, and copy the xbee-api jar file 
// and the log4j.jar file (located in the lib folder) inside a "code" 
// folder under this Processing sketch’s folder (save this sketch, then 
// click the Sketch menu and choose Show Sketch Folder).
import java.util.Queue;
import org.apache.log4j.PropertyConfigurator;
import java.util.concurrent.ConcurrentLinkedQueue;
import com.rapplogic.xbee.api.ApiId;
import com.rapplogic.xbee.api.PacketListener;
import com.rapplogic.xbee.api.XBee;
import com.rapplogic.xbee.api.XBeeResponse;
import com.rapplogic.xbee.api.zigbee.ZNetRxIoSampleResponse;



XBee xbee;
Queue<XBeeResponse> queue = new ConcurrentLinkedQueue<XBeeResponse>();
boolean message;
XBeeResponse response;

void setup() {
  try { 
    //optional.  set up logging
    PropertyConfigurator.configure(dataPath("log4j.properties")); 
    xbee = new XBee();
    // replace with your COM port
    xbee.open("COM20", 115200);

    xbee.addPacketListener(new PacketListener() {
      public void processResponse(XBeeResponse response) {
        queue.offer(response);
      }
    }
    );
  } 
  catch (Exception e) {
    System.out.println("XBee failed to initialize");
    e.printStackTrace();
    System.exit(1);
  }
}

void draw() {
  try {
    readPackets();
  } 
  catch (Exception e) {
    e.printStackTrace();
  }
}

void readPackets() throws Exception {

  while ((response = queue.poll()) != null) {
    // we got something!
    try {
      RxResponseIoSample ioSample = (RxResponseIoSample) response;

      println("We received a sample from " + ioSample.getSourceAddress());

      if (ioSample.containsAnalog()) {
        println("10-bit temp reading (pin 19) is " +
          ioSample.getSamples()[0].getAnalog1());
      }
    } 
    catch (ClassCastException e) {
      // not an IO Sample
    }
  }
}

thanks

Formatted code for you and moved the topic to a proper category (I think). See the sticky: To newcomers in this forum: read attentively these instructions

And "I have a problem" is a quite vague description of your issue...
What problem do you have? No data? Exceptions? Crash? Do you have error messages? Etc. Try and describe as precisely as you can your issue.

The problem is that when I run the code, it doesn't display any value. Thanks
