Arduino to Processing Communication Issue

hello,

i have code uses 2 temperature sensors. works great on arduino , able output serial monitor. problem comes when attempt send data processing , create .csv file data. arduino , processing both attempting use com3, , of course can't @ same time. processing creates .csv file, not have data in it. point out issue? have tried can think of @ point. code below:

arduino:

code: [select]

#include <onewire.h>
#include <dallastemperature.h>

#define one_wire_bus 2 /*-(connect pin 2 )-*/
#define bus2 4

onewire ourwire(one_wire_bus);
onewire ourwire2(bus2);

dallastemperature sensors(&ourwire);
dallastemperature sensors2(&ourwire2);

void setup()
{
 serial.begin(9600);
 delay(1000);

 sensors.begin();
}

void loop()
 serial.println();
 sensors.requesttemperatures();
 serial.print(sensors.gettempcbyindex(0));
 serial.print(",  ");
 sensors2.requesttemperatures();
 serial.print(sensors2.gettempcbyindex(0));

 delay(1000);
}



processing:

code: [select]

import processing.serial.*;


printwriter output;
dateformat fnameformat= new simpledateformat("yymmdd_hhmm");
dateformat  timeformat = new simpledateformat("hh:mm:ss");
string filename;

serial myport;
short portindex = 0;
char header = 'h';

void setup()
{
 size(200, 200);
 string portname = serial.list()[portindex];
 println(serial.list());
 println(" connecting -> " + serial.list()[portindex]);
 myport = new serial(this, portname, 9600);
 date = new date();
 filename = fnameformat.format(now);
 output = createwriter(filename + ".csv");
}

void draw()
{
 int val;
 string time;

 if ( myport.available() >= 15)
 {
   if( myport.read() == header)
   {
     string timestring = timeformat.format(new date());
     println("message received @ " + timestring);
     output.println(timestring);
     
     val = readarduinoint();
     // print value of each bit
     for(int pin=2, bit=1; pin <= 13; pin++){
       print("digital pin " + pin + " = " );
       output.print("digital pin " + pin + " = " );
       int isset = (val & bit);
       if( isset == 0){
          println("0");
          output.println("0");
       }
       else  {
         println("1");
         output.println("0");
       }
       bit = bit * 2;
     }
     // print 6 analog values
     for(int i=0; < 6; ++){
       val = readarduinoint();
       println("analog port " + + "= " + val);
       output.println("analog port " + + "= " + val);
     }
     println("----");
     output.println("----");
   }
 }
}

void keypressed() {
 output.flush();
 output.close();
 exit();
}

int readarduinoint()
{
 int val;      
 val = myport.read();        
 val =  myport.read() * 256 + val;
 return val;
}


thank in advance!!!

please use # button when posting code, becomes better readable. can modify post, select code , press # button above smileys proper tags.
thank you.
