Pinguino with Processing

I tried to connect Pinguino with Processing with the LibUSB java wrapper. It works without problem. This is the Processing test sketch:

// This is a simple example to communicate with Pinguino
// based on the LibusbJava wrapper http://libusbjava.sourceforge.net/wp/
// Jean-Pierre MANDON 05/03/2009

import ch.ntb.usb.Device;
import ch.ntb.usb.USB;
import ch.ntb.usb.USBException;
import ch.ntb.usb.logger.LogUtil;

// define Pinguino Product ID and Vendor ID
int VID = 0x04D8;
int PID = 0xFEAA;
// declare public USB device
Device Pinguino;
// declare output buffer
byte[] data = new byte[] { 'W', -1 };

void setup()
{
size(400,100);
frameRate(20);
LibusbJava.usb_init(); // init libusbjava
LibusbJava.usb_find_busses(); // find all usb busses
LibusbJava.usb_find_devices(); // find all devices
try {
Pinguino=USB.getDevice( (short) VID , (short) PID ); // create a new device
Pinguino.open(3,0,-1); // try to open it ( configuration 3, interface 0 )
println("Pinguino found"); // it's OK
}
catch (USBException e) // error
{
println("Pinguino not found"); // Pinguino is not connected !!
}
}

byte lastposition=-1;
byte position;

void draw()
{
background(204);
rect(mouseX,40,20,20); // draw a rectangle
position=byte(mouseX/50); // position modulo 8
if (position!=lastposition)
{
try {
if (lastposition!=-1) data[1]=lastposition;
else data[1]='C'; // WC clear all leds
Pinguino.writeBulk(0x01,data,2,200,false); // send command to Pinguino
data[1]=position; // led to be lighted
Pinguino.writeBulk(0x01,data,2,200,false); // send command
lastposition=position;
}
catch (USBException e) {}
}
}

void stop()
{
data[1]='C'; // clear all when stop
try {
Pinguino.writeBulk(0x01,data,2,200,false);
}
catch (USBException e) {}
}

Now this is the Pinguino side:

// test Pinguino with Processing
// Jean-Pierre MANDON 2009

int i;
uchar caractere,caractere1;

void setup()
{
for (i=0;i<8;i++)
{
pinMode(i,OUTPUT);
digitalWrite(i,LOW);
}
}

void loop()
{
if (USB.available())
{
caractere=USB.read();
if (caractere=='W') if (USB.available())
{
caractere1=USB.read();
if (caractere1=='C')
for (i=0;i<8;i++) digitalWrite(i,LOW);
else
digitalWrite(caractere1,digitalRead(caractere1)^1);
}
}
}

And you can see the result here.
