BOOSTXL-EDUMKII Educational BoosterPack™ Plug-in Module Mark II
3.1 BOOSTXL-EDUMKII_Accelerometer_MSP432P401R
This section describes the functionality and structure of the BOOSTXL-
EDUMKII_Accelerometer_MSP432P401R demo that is included in the
MSP-EXP432P401R Software
Examples download, or more easily accessible through the SimpleLink MSP432 SDK (see Section 4.3 ).
3.1.1 Source File Structure
The project is split into multiple files (see Table 14 ). This makes it easier to navigate and reuse parts of it
for other projects.

3.1.2 Operation
This demo uses the MSP432 built-in ADC14 to sample from the 3-axis acceleration data output of the
analog accelerometer on the Educational BoosterPack plug-in module MKII (see
Figure 4 ). The measured
14-bit acceleration data are displayed on the BoosterPack plug-in module's colored 128x128 dot-matrix
LCD. Using
MSP Graphics Library , the MSP432 MCU sends data to the LCD controller through SPI
communication to draw texts.
Figure 4. 3-Axis Analog Accelerometer
The demo makes use of the acceleration data by changing the LCD orientation when the BoosterPack
plug-in module is tilted in the corresponding direction.
