serial and processing code

PROCESSING CODE

float[] data = new float[2]; // create 2 space data array. 1) Potentiometer and 2) photocell
int index=0;
float xpos;
int bck;

void setup() {
size(255,255);
beginSerial(); //begin serial communication thing
serialWrite(65); //talk to PIC . like saying hello
}

void loop() {
background(bck);
fill(0,0,244);
ellipse(xpos, 100, 50,50); //movable circle

}

void serialEvent() { //automatic serial listener
data[index] = serial; // save messages to data array
index=index+1; // increment serial counter

if (index==2) { // both messages received

xpos = float(data[0]); // rename the first message to xpos
bck = int(data[1]); //save photocell value
serialWrite(65); // responsd back to PIC
index = 0; // reset serial counter to zero
}

}
