The TS-7180 has an optional MPU-9250 motion-tracking device. This device provides:

  • 3-axis Gyroscope
  • 3-axis Accelerometer
  • 3-axis Magnetometer
  • Temperature sensor

The MPU-9250 is connected to the CPU via I2C. The device is actually two chips in one: The first contains the gyroscope, accelerometer, and temperature sensor. The second contains the magnetometer. Because there are two chips, there are two I2C chip addresses: 0x69, and 0x0C.

User interface to the device is done through the sys filesystem.

The gyroscope, accelerometer, and temperature readings are available at:

/sys/bus/iio/devices/iio:device1

The magnetometer readings are available at:

/sys/bus/iio/devices/iio:device2
