Data communication from Arduino/Processing Post #1

Processing Electronics (Arduino, etc.)

Hi, Thanks for the suggestion,
I did an application where I recieved my data from the arduino and decplayed them in graph
now I just need put the data that I recieved in tabular in processing
this is what I did

//Variables to draw a continuous line.
int lastxPos=1;
int lastheight=0;

void setup () {
  // set the window size:
  size(600, 400);        

  myPort = new Serial(this, "COM5", 9600);  

  // A serialEvent() is generated when a newline character is received :
  myPort.bufferUntil('\n');
  background(0);      // set inital background:
}
void draw () {
  if (newData) {
    //Drawing a line from Last inByte to the new one.
    stroke(127,34,255);     //stroke color
    strokeWeight(4);        //stroke wider
    line(lastxPos, lastheight, xPos, height - inByte); 
    lastxPos= xPos;
    lastheight= int(height-inByte);

    // at the edge of the window, go back to the beginning:
    if (xPos >= width) {
      xPos = 0;
      lastxPos= 0;
      background(0);  //Clear the screen.
    } 
    else {
      // increment the horizontal position:
      xPos++;
    }
   newData =false;
 }
}

void serialEvent (Serial myPort) {
  // get the ASCII string:
  String inString = myPort.readStringUntil('\n');
  if (inString != null) {
    inString = trim(inString);                // trim off whitespaces.
    inByte = float(inString);           // convert to a number.
    inByte = map(inByte, 0, 1023, 0, height); //map to the screen height.
    newData = true; 
  }
}
