I want to define:

byte myNumber = B10101010;

That works fine in arduino but doesn't seem to work in Processing 2.0. I can't seem to find the right syntax for this. Anyone know how to do it?

Hi,

I am using processing 1.5.1 with the gifAnimation library, which just unpacks the gif in to a PImage[] array.

During setup I load a gif using:
   myGIf = new Gif(this, fileNames[firstFile]);


However, after a while I want to replace what is playing with another file and so I do the same but with another:
  myGIf = new Gif(this, fileNames[secondtFile]);


And later I load another file again and then back to the first. The program just accumulates more and more memory until it goes out of memory.

Does anyone have an idea what I am doing wrong?

Thank you!

Google found a few previous questions about this, but no answers.

I have 2 camera's, the exact same model, attached to a usb hub.

If I list the camera's in processing 2.0b9 I can see both cameras.

I can however not select the one I want because they have the same name,
processing always end up picking the same one.

Is there a solution for this. Can I select a camera by the windows device id or something?

Hi,

I have a very simple sketch.

De webcam saves an image every second and the images are numbers from 0 to x. Then in draw() I load one of those images and display it. The result is a timelaps video that always updates.

Great! Unfortunately it runs out of memory rather quickly.

My question, is there any way I can create an Image and reload it's content from draw() ?

Here's my code:
----------------------------- 
import processing.video.*;
Capture myCapture;
String[] cameras = Capture.list();
int frame=1;
int maxFrames=100;
int savedFrame=0;
int delay=0;
PImage displayImage;
int playbackDelay=0;

void setup()
{
  frameRate(30);
 
  size(320, 240);
  myCapture = new Capture(this, 320, 240, 30);
  myCapture.start();
 
  //myCapture.stop();
}

void captureEvent(Capture myCapture) {
  myCapture.read();
}

void draw() {
//  background(0,0,0);

    if (delay>30){
      image(myCapture, 0, 0, 320, 240);
      savedFrame++;
      if (savedFrame>maxFrames){
        savedFrame=0;
        }
      save("currentFrame"+savedFrame+".png");
      delay=0;
      }
  delay++;
     

  frame++;
  if (frame>maxFrames){
    frame=0;
    }

      // Load one of the saved images and display it every x frames for timelaps effect.
  playbackDelay++;
   if (playbackDelay>3){
    displayImage = loadImage("currentFrame"+frame+".png");
    image(displayImage, 0, 0, 320, 240);
    playbackDelay=0;
   }
}
