Yup - works pretty well with Ess:

}
void draw(){ background(250);
stroke(0);
// Graph the stored values by drawing a lines between them. for (int i = 0; i <> 0){ serialEvent(port.read()); } // image(etch,0, 0, width, height);}
void serialEvent(int serial){ if (serial != NEWLINE) { // Store all the characters on the line. buff += char(serial); } else { // The end of each line is marked by two characters, a carriage // return and a newline.

// Parse the String into an integer. We divide by 4 because // analog inputs go from 0 to 1023 while colors in Processing // only go from 0 to 255. int x = Integer.parseInt(buff1)/2; int y = Integer.parseInt(buff2)/2;
// Clear the value of "buff" buff = "";
// Shift over the existing values to make room for the new one. for (int i = 0; i < 255; i++) { valuesx[i] = valuesx[i + 1]; valuesy[i] = valuesy[i + 1]; }
