processing problem
Oct 27th, 2008, 4:22am  
Hello,
I am connecting a simple sketch on arduino to processing, my processing code looks just fine, but I seem to have some sort of a java or server problem.
I am using a Macbook pro OSX 10.5.5 with the latest java installed. arduino 10 and processing 0154.

this is the error message I get:


processing.app.debug.RunnerException: unexpected token: void

This is part of my processing code - the beginning:


import processing.serial.*;
import processing.net.*;
Server myServer;
myServer = new Server(this, 8080);
int ZERO = 0;
 
// variables for serial connection, portname and baudrate have to be set
 Serial port;
 String portname = "/dev/tty.usbserial-A9003VR1";  
 int baudrate = 9600;
 int value = 0;
 String buf="";
 int value1=0;  


void setup(){
 // set size and framerate
 size(xWidth, yHeight);
 //frameRate(fr);
 // establish serial port connection      
 println(port.list());
 port = new Serial(this, portname, baudrate);
 // create DisplayItems object
 di = new DisplayItems();
}


how can it be fixed ?
thank you.

You can't do:

Server myServer;
myServer = new Server(this, 8080);

in that mode of processing, you need to put the "myServer = ..." line into setup()
