ITG-3200 Gyroscope Library for Arduino

Here's the first revision of a library I made for the ITG-3200 3-Axis Gyroscope made by Invensense.

The sensor communicates using the I2C protocol with other devices, for which I'm making use of the Wire library.

You will have to include Wire.h in your sketches if you plan to use this library.

Here's an example of how to use it (assuming you have already made the electrical connections):

#include "itg3200.h"

ITG3200 gyro;

void setup(){

Serial.begin(9600);

gyro.begin(0x69); // as for SparkFun breakout, all default values

delay(1);

}

void loop(){

Serial.print("X=");

Serial.println(gyro.getX());

Serial.print("Y=");

Serial.println(gyro.getY());

Serial.print("Z=");

Serial.println(gyro.getZ());

delay(400);

}

Running this sketch will make the Arduino transmit the readings for each axis through the first serial module every 400 milliseconds.

UPDATE: This library has been updated as of January 16th, 2011.
