I would like to host on an external server SharedCanvasServer.pde, so anyone getting to the corresponding webpage could draw on my PC SharedCanvasClient display window. How can I do that?
Should I put the sketch in an HTML file the way Processing.js does it?

I tried to use the Arduino Labs tutorial for the Accessory mode ( http://labs.arduino.cc/ADK/AccessoryMode) on my Samsung Galaxy 10.1 tab with no success. The Arduino examples (e.g.: analogread) uploads alright on the Mega ADK board, but for the corresponding Processing example I get the following error message:

Any help?
PS: the ADB mode works alright, though!

I would like to add a picture in the controlWindow but I don't know how to it. I tried

When I try to export as a Windows application the example "Loop" of the GSVideo distribution I get an .exe OK, but if I run it, it gives a blank screen with just the stop button.
I use Vista and Processing 1.2.1
Any idea why?

I have sketch with videos and sounds which is working fine, but when I try to export it I get the following error message:

Does anyone know what can be the cause of this problem?
Thanks!

If I merge an example given in the Processing Serial distribution, "Simple Read" with an example given in Ardiuno Communication distribution "Physical Pixel" I get one code for the Arduino:

1. const int ledPin = 13; // the pin that the LED is attached to
   int incomingByte;      // a variable to read incoming serial data into
   int switchPin = 4; 
   void setup() {
     // initialize serial communication:
     Serial.begin(9600);
     // initialize the LED pin as an output:
     pinMode(ledPin, OUTPUT);
     pinMode(switchPin, INPUT);
   }
   
   void loop() {
     // see if there's incoming serial data:
     if (Serial.available() > 0) {
       // read the oldest byte in the serial buffer:
       incomingByte = Serial.read();
       // if it's a capital H (ASCII 72), turn on the LED:
       if (incomingByte == 'H') {
         digitalWrite(ledPin, HIGH);
       }
       // if it's an L (ASCII 76) turn off the LED:
       if (incomingByte == 'L') {
         digitalWrite(ledPin, LOW);
       }
     }
    
     if (digitalRead(switchPin) == HIGH) {  // If switch is ON,
       Serial.print(1, BYTE);               // send 1 to Processing
     } else {                               // If the switch is not ON,
       Serial.print(0, BYTE);               // send 0 to Processing
     }
    
     delay(100);
   }

and another on for Processing:

1. import processing.serial.*;
    
    float boxX;
    float boxY;
    int boxSize = 20;
    boolean mouseOverBox = false;
    int val;
    Serial port;
    
    void setup()  {
    size(200, 200);
    boxX = width/2.0;
    boxY = height/2.0;
    rectMode(RADIUS);
    
    // List all the available serial ports in the output pane.
    // You will need to choose the port that the Arduino board is
    // connected to from this list. The first port in the list is
    // port #0 and the third port in the list is port #2.
    println(Serial.list());
    
    // Open the port that the Arduino board is connected to (in this case #0)
    // Make sure to open the port at the same speed Arduino is using (9600bps)
    port = new Serial(this, Serial.list()[2], 9600);
    
    }
    
    void draw()
    {
    if ( port.available() > 0) {  // If data is available,
       val = port.read();         // read it and store it in val
     }
     //background(255);             // Set background to white
     if (val == 0) {              // If the serial value is 0,
       fill(0);                   // set fill to black
     }
     else {                       // If the serial value is not 0,
       fill(204);                 // set fill to light gray
     }
     rect(50, 50, 100, 100);
    
    // Test if the cursor is over the box
    if (mouseX > boxX-boxSize && mouseX < boxX+boxSize &&
    mouseY > boxY-boxSize && mouseY < boxY+boxSize) {
    mouseOverBox = true; 
    // draw a line around the box and change its color:
    stroke(255);
    fill(153);
    // send an 'H' to indicate mouse is over square:
    port.write('H');      
    }
    else {
    // return the box to it's inactive state:
    stroke(153);
    fill(153);
    // send an 'L' to turn the LED off:
    port.write('L');     
    mouseOverBox = false;
    }
    
    // Draw the box
    rect(boxX, boxY, boxSize, boxSize);
    }
    
   

Unfortunately, only the square is changing color on the computer side and the led is not blinking on the Arduino.
Apparently, I got a problem with the serial communication.
I would appreciate some help! Thanks!

I want to see an image through a moving circle. I have it working in two different ways inside the black display windows.
First solution:

1.  PImage a;
   void setup()
   {
     size(800,800);
    a = loadImage("tableau1.jpg");
   }
   void draw()
   {
     background(0); 
    noStroke();
    fill(255);
    ellipse(mouseX,mouseY, 150, 150);
   blend(a,0,0,800,800,0,0,800,800,DARKEST);
   }

Second solution:

1. PImage a;
   void setup() {
     size(800, 800);
     a = loadImage("tableau1.jpg");
   }
   void draw(){
     noStroke();
     fill(0);
   rect(0, 0, 800, 800);
   fill(255);
   ellipse(mouseX, mouseY, 150, 150);
   PImage imask = get();
   a.mask(imask);
   image (a,0,0);
   }

 But when I try to get it inside of a BLACK CIRCLE (which is what I want) I cannot get it!
Any idea on how to do it?
Thanks!
