2 windows with processing on one computer

in Integration and Hardware • 1 year ago

hello everybody,

i am new here and a beginner with processing. i was doing some projects with arduino.
my newest project is the following:

i want to have two different visualisations of data on two different monitors. the data comes from bioera, a neurofeedback programm, through serial comunication to an arduino. that is working so far nicely. till now i am controlling leds with the arduino. now i want to visualize the data on two monitors. for example, if alpha amplitude on a particular position is high, a big circle appears on the left monitor, and if theta is low on another location, a red triangle would appear on the right monitor.

data should flow quite fast, maybe in a range of a few hundreds of a second.

i thought i would use in total 2 computers. on the first one is the neurofeedback software, where i use two monitors for the neurofeedback software.
on the second one i would run processing and in two different windows in two monitors.
the first arduino attached to the neurofeedback software i would connect to two other arduinos through serial communication, and these two arduinos are connected to the second computer running processing.
is that a possible setup, could one window of processing process data from one arduino, for example on port 1, and the other window process data from an arduino at port 2?

thanks for your help and if there is an easier way i would be happy to hear about.

I know... absolutely nothing about the Arduino aspect of this, but if you're looking for help supporting multiple screens, though...

The best way to do this (in my opinion) is to have two fullscreen windows, one for each screen. In order to do that, you will need to create a second window. There have been numerous threads already on this topic, such as this one. I like to use an approach described ~~here~~ . Scratch that, I can't find the link... and I can't find my code, so try using this for now:

import javax.swing.JFrame;
PFrame f;
secondApplet s;
void setup() {
size(320, 240);
PFrame f = new PFrame();
}
void draw() {
background(255,0,0);
fill(255);
rect(10,10,frameCount%100,10);
s.background(0, 0, 255);
s.fill(100);
s.rect(10,20,frameCount%120,10);
s.redraw();
}
public class PFrame extends JFrame {
public PFrame() {
setBounds(100,100,400,300);
s = new secondApplet();
add(s);
s.init();
show();
}
}
public class secondApplet extends PApplet {
public void setup() {
// size(400, 300);
// noLoop();
}
public void draw() {
}
}

i want to play two movies in both main and extrawindow. But some how they both are playing in same window.

Here is my code

import controlP5.*;

import processing.opengl.*;

import codeanticode.gsvideo.*;

import codeanticode.glgraphics.*;

ControlP5 controlP5;

ControlWindow controlWindow;

ControlWindowCanvas cc;

GSMovie myMovie;

GSMovie myMovie2, nowPlaying;

GLTexture tex;

// this example demonstrates how to use a ControlWindowCanvas

// which can from different windows.

// click the mouse in both windows to see the effect.

// your controlWindowCanvas class

class MyCanvas extends ControlWindowCanvas {

public void draw(PApplet theApplet) {

theApplet.background(255);

if(mousePressed) {

myMovie2.pause();

myMovie2.jump(0);

nowPlaying = myMovie;

nowPlaying.loop();

}

if(theApplet.mousePressed) {

myMovie.pause();

myMovie.jump(0);

nowPlaying = myMovie2;

nowPlaying.loop();

}

void setup() {

size(960, 540, GLConstants.GLGRAPHICS);

background(0);

tex = new GLTexture(this);

myMovie2 = new GSMovie(this, "dino.mov" );

myMovie = new GSMovie(this, "solar.mov" );

nowPlaying = myMovie;

nowPlaying.loop();

controlP5 = new ControlP5(this);

controlWindow = controlP5.addControlWindow("controlP5window",width,height);

controlWindow.setUpdateMode(ControlWindow.NORMAL); // It updates the previous value

// create a control window canvas and add it to

// the previously created control window.

cc = new MyCanvas();

// cc.pre(); // use cc.post(); to draw on top of existing controllers.

controlWindow.addCanvas(cc); // add the canvas to controlWindow

}

void draw(){

image(nowPlaying,0,0,width,height);

}

void movieEvent(GSMovie _mov){

_mov.read();

}

thanking you in anticipation.....

calsign,

thanks for your response. i was trying out a little yesterday and found out that i could just open two processing windows, like open two windows explorers. each of them had their own window, and they work seperately. can i not just open two programs? as a beginner, i would like to keep it easy.
am i right that with your method you just run one processing sketch and in the sketch you determine in which window something should be painted?

thanks,
michael

If you run two programs, then the two cannot easily interact (at the very least, it will create a lot of problems). In my opinion, at least, I think it would be a better choice to create one program. Even if your application does not require this interaction now, you may later decide that you want more to happen, and it will become incredibly difficult.

calsign,
thanks for your advice. i am sure the two windows are absolutely not required to interact with each other, they are totally independent.
so i guess then i pick the easier version with two programs.
