Hi,

I recently tried to put a simple code to capture a serial data from a microcontroller and display it. When I run the code, it works fine. But when I export it as an applet and use it using the web browser, it doesnt capture the serial data. Any configurations need to be performed for this?

Thanks

EDIT: Also, is there a way to save the images from saveFrame() to different folder other than the project folder?

here is the code:

1. import processing.serial.*;
   
   int temp;
   Serial mfport;
   PFont mffont;
   void setup(){
   mffont = loadFont("davud.vlw");
   println(Serial.list());
   String cport = "COM23";
   mfport = new Serial(this,cport,9600);
   
   }
   void draw(){
   
   while(mfport.available()>0){
   background(255);
   temp = mfport.read();
   println(temp);
   fill(0);
   String par = nf(temp,2,0);
   text(par,20,20);
   }
   }

Hi,

I am a noob in processing, and I need a help in reciprocating a block in a loop. I have implemented it. But wanna know if there is any code simpler than this!.

The receiprocation must be in a loop (like the piston in crank slider mechanism).

1. here is the code what i tried:
   
   int x=300,y=0;
   void setup(){
   size(640,320);
   }
   void draw(){
   background(0,0,y);
   rect(x,200,30,70);
   if(y<100)
   x++;
   y++;
   if(y>=100){
   x--;}
   if(y>200){
   y=0;
   x=300;}
   
   }

is there any simple way to do it?

Thanks for your help.

I want to design a moving object in 2d. Basically, I chose a triangle and i can only move it up and down. All I need is, when I press left button, it must rotate counter-clockwise and when i press right, it must rotate clockwise and then continue in that direction when up/down is pressed. 

Here is my code:

2. int x0=200,y0=200,x1=205,y1=230,x2=195,y2=230;
3. void setup()
4. {
5.   size(400,400);
6. }
7. void draw()
8. {
9.   background(0,255,0);
10.   stroke(0);
11.   smooth();
12.   triangle(x0,y0,x1,y1,x2,y2);
13. }
14. void keyPressed()
15. {
16.   if(key==CODED)
17.   {
18.     if(keyCode==UP)
19.     {
20.       y0--;y1--;y2--;
21.     }
22.     if(keyCode==DOWN)
23.     {
24.       y0++;y1++;y2++;
25.     }
26.   }
27. }

Hi,

I am trying to play a sound file in processing. When i play the sound file, it starts away nice. but as time progress, the sound seems to distort/sound rapidly (the sound becomes indistinct.) I tried different bitrate and also without bitrate.

I wanted to loop a sound file until a condititon is met.

Thanks for your help
