Nine Axis Sensor Fusion with the MPU9150 and
Complimentary-Filtered DCM (compdcm_mpu9150)
This example demonstrates the basic use of the Sensor Library, TM4C123G LaunchPad and Sen-
sHub BoosterPack to obtain nine axis motion measurements from the MPU9150. The example
fuses the nine axis measurements into a set of Euler angles: roll, pitch and yaw. It also produces
the rotation quaternions. The fusion mechanism demonstrated is complimentary-filtered direct co-
sine matrix (DCM) algorithm is provided as part of the Sensor Library.
Connect a serial terminal program to the LaunchPad’s ICDI virtual serial port at 115,200 baud. Use
eight bits per byte, no parity and one stop bit. The raw sensor measurements, Euler angles and
quaternions are printed to the terminal. The RGB LED begins to blink at 1Hz after initialization is
completed and the example application is running.
2.3
Humidity Measurement with the SHT21 (humid-
ity_sht21)
This example demonstrates the basic use of the Sensoror Library, TM4C123G LaunchPad and
SensHub BoosterPack to obtain temperature and relative humidity of the environment using the
Sensirion SHT21 sensor.
Connect a serial terminal program to the LaunchPad’s ICDI virtual serial port at 115,200 baud. Use
eight bits per byte, no parity and one stop bit. The humidity and temperature as measured by the
SHT21 is printed to the terminal. The RGB LED begins to blink at 1Hz after initialization is complete
and the example application is running.
2.4
Light Measurement with the ISL29023 (light_isl29023)
This example demonstrates the basic use of the Sensor Library, TM4C123G LaunchPad and the
SensHub BoosterPack to obtain ambient and infrared light measurements with the ISL29023 sen-
sor.
Connect a serial terminal program to the LaunchPad’s ICDI virtual serial port at 115,200 baud. Use
eight bits per byte, no parity and one stop bit. The raw sensor measurements are printed to the
terminal. The RGB LED blinks at 1Hz once the initialization is complete and the example is running.
