Hello, I'm an Italian student !
I'm developing some little and simple projects for a communication between the Arduino and the ipod Touc.
I've correctly downloaded a touchOSCEditor layout on my ipod with a pushbutton called "OFF", then i tried this code on Processing:

1. import oscP5.*;
   import netP5.*;     
   import processing.serial.*;
   Serial arduino;
   OscP5 oscP5;
   
   void setup() {
       oscP5 = new OscP5(this,8000);
       arduino = new Serial(this,"/dev/ttyUSB0", 9600);
   }
   
   void oscEvent(OscMessage theOscMessage) { 
       String addr = theOscMessage.addrPattern();
          if(addr.indexOf("/OFF") != 0){
            arduino.write("");
           }
           else{
             arduino.write("-");
           }
   }
   void draw{}

The problem is that it seems that the Processing doesn't receive anything from the 8000 port.

Could anyone help me ?
