Javelin stamp and LISY300 communication

Hi all,

I've encountered a problem with my javelin. My javelin and my gyro (lisy300) won't communicate properly. I do get signals which vary as a gyro should, but they aren't correct. I've connected all wires like on the example code on the BS2. Here is my code:

CODE

import stamp.core.*;
import stamp.math.*;




class gyrotest{


static int dout;
static int sclk;
static int csn;


static int value;


public static void main() {
dout=CPU.pin0;
sclk=CPU.pin1;
csn=CPU.pin2;
value=0;


CPU.writePin(csn,true);
CPU.writePin(sclk,false);
CPU.delay(500);


value=readGyro();
forst=value;
while(true){
value=readGyro();
System.out.println(value/*area*/);
CPU.delay(50);
}
}


public static int readGyro(){


CPU.writePin(csn,false);
int x=CPU.shiftIn(dout,sclk,13,CPU.POST_CLOCK_MSB);
CPU.writePin(csn,true);


return x;
}
}


CODEEND

I think there is a problem with the trailing zeroes or something like that.

Example of output is:
0
0
0
0
3
0
0
0
0
0
0
6
0
0
3
3
0
