BOOSTXL-SENSORS Sensors BoosterPack Plug-in Module
The IMU tile is different from the other tiles in the following ways:
•
It is made up of two parts, the BMI160 and the BMM150, each in its own box.
•
Each box consists of graphs and numerical data, which are color coded to correspond to one another.
•
Each part has its own sample rate selector.
•
It has a hint button for each type of sensor; the accelerometer, gyroscope, and magnetometer.
The accelerometer has a display for the acceleration vector magnitude.
The ON/OFF toggle button puts the BMM150 into hibernate and the BMI160 into pedometer mode, and
only the accelerometer remains active.

Figure 8. GUI Integrated EnergyTrace Measurements
This section provides monitoring of system current using TI's EnergyTrace technology. It consists of:
1. A hint button. Explains EnergyTrace software measurements and displays a table of expected sensor
currents.
2. A start button. Press this to shift any previous data down to the next time frame, clear the graph, and
begin the next measurement for the selected duration.
3. An input box. To set the duration in milliseconds, click the arrows or type a value:
4. The past three sensor settings and current measurements, with the most recent on top.
5. A graph showing the actual current draw over time. The X-axis corresponds to 0.5-ms ticks, the Y-axis
to the current in milliamps. Each peak is a good indicator of when the MCU is in active mode, and the
valleys indicate when the MCU is in LPM0.
This implementation is an abbreviated form of EnergyTrace software. The full version can track power
consumption, power mode, and more. EnergyTrace software can be used on any application through
Code Composer Studio IDE v6 or IAR Embedded Workbench. For more information, visit
