Hi,
I am using TouchOSC to control a multiple LED light.
Thus I created a TouchOSC Layout with 4 pages, each containing 5 faders.
The faders are named fader0....fader4 on each page.

I am already able to control my arduino with the fist page using following code.
It sends 7 bytes to my arduino via serial:
1) a or b (button that switches control on or off
2) c,d,e or f => these should tell my arduino on which page I am
3) fader 0 to fader 4 (0-255)

1. 
   

2. import oscP5.*;

   import netP5.*;

   import processing.serial.*;

   Serial myPort;

   OscP5 oscP5;

   int [] fader = new int [5];

   float button0;

   int [] out = new int [5];

   int [] menu = new int [5];

    

   void setup() {

      oscP5 = new OscP5(this,8000);

      myPort = new Serial(this, "COM13", 19200); }

    

   void oscEvent(OscMessage theOscMessage) {

      String addr = theOscMessage.addrPattern();

      float val = theOscMessage.get(0).floatValue();

      if(addr.equals("/1/button0")) {

        button0 = val;

      }

      if(addr.indexOf("/1/fader") !=-1){

        String list[] = split(addr,'/');

        int i = int(list[2].charAt(5) - 0x30);

        fader[i] = (int) val;

      }

   }

    

   void draw() {

      while (button0==1) {

        for (int i=0; i<5; i++) {

          if (fader[i] != out[i]) {    

            out[i] = (int) (fader[i]);

            myPort.write('a');

            myPort.write('d');    

            for (int j=0; j<5; j++) {

              myPort.write(out[j]);

              println(out[j]);

            }

          }

        }

      }

   }

    

My question is: How do I have to change my "void oscEvent(OscMessage theOscMessage)", to split the adress names, so that page-number is dynamic?
if(addr.indexOf("/1/fader") !=-1){

     String list[] = split(addr,'/');

     int i = int(list[2].charAt(5) - 0x30);

     fader[i] = (int) val;

   }

=> /1/fader/ should also become /2/fader, /3/fader and /4/fader. Of course I could create this part four times but I was thinking of some better solution by splitting this value. Any idea?

Thx
