Processing export to OSX, did not work with serial port communication

in Integration and Hardware • 1 month ago

Dear all

I wrote a simple code , using Arduino switches to move a simple image on Processing left and right.

It works when I run the code from Processing window. But when exporting to OSX app, it stops working! I try to debug and isolate the problem a bit: i think it is the serial communication. any solution??

Processing code:

//this code reads from serial port and move Mario around
//based on the switch pressed on Arduino board
// import the serial library
import processing.serial.*;
import gifAnimation.*;
// create an instance of the serial library
Serial myPort;
// create an instance of PImage
//PImage[] animation;
Gif loopingGif;
Gif loopingGif2;
int keypress =0;
void setup() {
size (500, 500);
frameRate(100);
loopingGif = new Gif(this, "mario3.gif");
loopingGif.loop();
loopingGif2 = new Gif(this, "mario14.gif");
loopingGif2.loop();
println("Available serial ports:");
println(Serial.list());
myPort = new Serial(this, Serial.list()[0], 9600);
}
int x=0;
int y=50;
void draw() {
if ( myPort.available() > 0) {
keypress = myPort.read();
// print the value to the status window
println(keypress);
}
background(255);
image(loopingGif, x, y, loopingGif.width* 2, loopingGif.height*2);
if (keypress == 1) {
x ++ ;
image(loopingGif, x, y, loopingGif.width* 2, loopingGif.height*2);
}else if (keypress == 2){
x --;
image(loopingGif, x, y, loopingGif.width* 2, loopingGif.height*2);
}else if (keypress == 3){
background(255);
image(loopingGif2, x, y-20, loopingGif2.width* 2, loopingGif2.height*2);
}
}

Arduino code

//this code write byte into serial port based on the switch pressed
//processing will read the serial port and move Mario spirite on the screen
//it is a basic game controller
void setup() {
Serial.begin(9600);
pinMode(A0, INPUT);
}
void loop(){
int keypress = analogRead(A0);
//Serial.println(analogRead(A0));
if (keypress >=1022) { //first key pressed
//Serial.println("1");
Serial.write(1);
} else if (keypress >1000 && keypress <=1002) { //2nd key pressed
//Serial.println("2");
Serial.write(2);
} else if (keypress >500 && keypress <=999) {//third key press
//Serial.println("3");
Serial.write(3);
} else if (keypress >0 && keypress <=10) {//fourth key pressed
// Serial.println("4");
Serial.write(4);
} else if (keypress ==0){
//Serial.println("0");
Serial.write(0);
}
delay(100);
}

thanks a lot!
