Introduction

Grove – 3-Axis Digital Gyro module based on ITG 3200. It is the world’s first single-chip, digital-output, 3-axis MEMS motion processing gyro optimised for gaming, 3D mice, and motion-based remote control applications for Internet connected Digital TVs and Set Top Boxes. The ITG-3200 features three 16-bit analog-to-digital converters (ADCs) for digitising the gyro outputs, a user-selectable internal low-pass filter bandwidth, and a Fast-Mode I2C (400kHz) interface.

Demonstration

This demo will show you how to get data from this digital gyro, the data is in the unit of rad/s.

Here we need a Grove – 3-Axis Digital Gyro and a Seeeduino V3.0.

Hardware Installation

Hardware installation is very easy, because there’s an I2C Grove in Seeeduino,

so what we need to to is connect it to I2C Grove via a Grove cable.

Download Code and Upload

You can download the library in github, click here, then extract it to libraries folder of Arduino.

Then open File -> examples -> Grove_3_Digital_Gyro -> ITG3200_gyro, you can open the demo code.
