Large Delay when using Serial data from Arduino

Jourd123

Hello,

I am having trouble getting my sketch to respond to my ardunio in actual time. There is about a 30 second delay. The delay gets longer as the sketch continues to run.

My goal: under certain conditions from the Arduino a sprite will play in processing. There are 4 condition (1 0, 1 1, 2 0, 2 1).

Code:

int numFrames = 7; int currentFrame = 0; PImage[] images = new PImage[numFrames];

import processing.serial.*; Serial myPort;
String val;

void setup() { size(1000,600); frameRate(5);

images[0] = loadImage("images/heart(1).gif"); images[1] = loadImage("images/heart(2).gif"); images[2] = loadImage("images/heart(3).gif"); images[3] = loadImage("images/heart(4).gif"); images[4] = loadImage("images/heart(5).gif"); images[5] = loadImage("images/heart(6).gif"); images[6] = loadImage("images/heart(7).gif");

String portName = Serial.list()[1]; myPort = new Serial(this, portName, 9600);

}

void draw() { background(255);

//Display Serial Data if (myPort.available() > 0) { if ( (val = myPort.readStringUntil(ENTER)) != null ) val = trim(val); else return; if (val != null) { println(val); } }

//control sketch currentFrame = (currentFrame+1) % numFrames; // Use % to cycle through frames int offset = 0;

if ("1 1".equals(val)) {
image(images[(currentFrame+offset) % numFrames], 333, 200);
offset+=2;

}

if("2 1".equals(val)){
image(images[(currentFrame+offset) % numFrames], 666, 200);
offset+=2;
player.play();
}

}

Any help is greatly appreciated!
