Xadow - IMU 9DOF

Xadow - IMU 9DOF is a high performance 9-axis motion tracking module,which is base on MPU-9150.The MPU-9150 is the world's first integrated 9-axis motion tracking device designed for the low power, low cost, and high performance requirements of consumer electronics equipment including smartphones, tablets and wearable sensors .MPU-9150 features three 16-bit ADC for digitizing the gyroscope outputs and three 16-bit ADCs for digitizing the accelerometer outputs and three 13-bit ADCs for digitizing the magnetometer outputs.

Specification


  • I2C interface
  • Low cost
  • 400kHz Fast Mode I2C for communicating with all registers
  • Digital-output X-, Y-, and Z-Axis angular rate sensors (gyroscopes) with a user-programmable full-scale range of ±250, ±500, ±1000, and ±2000°/sec
  • Digital-output 3-Axis accelerometer with a programmable full scale range of ±2g, ±4g, ±8g and ±16g
  • 3-axis silicon monolithic Hall-effect magnetic sensor with magnetic concentrator

Interface Function


  • ①:12P FPC bottom contact
  • ②:Address select resistor:R4,R5(default address is 0x68)
  • Address is 0x68: R4 is not soldered.
  • Address is 0x69: R5 is not soldered.

Usage


Based on library,we can display value of Accle&Gyro&Magnet on serial monitor.Now let's show how to use the module.

Hardware Installation

Hardware instration is very easy,It can connect to Xadow - Main Board by FPC cable.

Software Part 1. Download the library libraries.zip; 2. Unzip libraries into the libraries file of Arduino IDE by the path: ..\arduino-1.0.5\libraries. 3. Unzip IMU_9D0F_Demo file into the libraries file of Arduino IDE by the path: ..\arduino-1.0.5\libraries. 4. Open the code directly by the path: File -> Example -> IMU_9D0F_Demo 5. Upload the code. Note that you should select the correct board type and COM port. 6. You can see :

In static state,the z-Axis output value is about 0.98g,so you can refer to this to test if your sensor can work normally.

**Orientation of Axes **

The diagram below shows the orientation of the axes of sensitivity and the polarity of rotation.
