Class BO.io.GyroITG3200

Extends BO.I2CBase.

Creates an interface to an ITG3200 3-axis gyroscope. This gyro measures angular acceleration around the x, y, and z axis. This object provides the angular velocity of each axis. Proper calibration is required for an accurate reading. See Breakout/examples/sensors/itg3200.html and Breakout/examples/processing_js/gyro.html for example applications.

Defined in: GyroITG3200.js.

Class Detail

BO.io.GyroITG3200(board, autoStart, address)

InvenSense ITG3200 3-axis MEMS gyro

Parameters:
{IOBoard} board: The IOBoard instance
{Boolean} autoStart: True if read continuous mode should start automatically upon instantiation (default is true)
{Number} address: The i2c address of the accelerometer. If pin 9 (AD0) of the module is tied to VDD, then use GyroITG3200.ID_AD0_DVV (0x69), if pin 9 (AD0) is tied to GND, then use GyroITG3200.ID_AD0_GND. Default = GyroITG3200.ID_AD0_VDD
