1. Introduction Grove - 3-Axis Digital Gyro module based on ITG 3200. It is the world’s first single-chip, digitaloutput, 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 userselectable internal low-pass filter bandwidth, and a Fast-Mode I2C (400kHz) interface.
2. Features Supply Voltage: 3.3V, 5V Operation Current: 6.5mA Standby current: 5μA Sensitivity: 14 LSBs per °/sec Full scale range: ±2000°/sec Acceleration: 10,000g for 0.3ms I2C Interface ±2000°/s full scale range and 14.
3. 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. 3.1 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. 3.2 Download Code and Upload You can download the library in github, click here, then extract it to libraries folder of Arduino.
