3.3 430BOOST-SHARP96 Graphics Library Example
This software example is similar to the BOOSTXL-K350QVG-S1 Graphics library example. It shows how
to use the MSP Graphics Library, or "grlib," in a project with the Sharp 96×96 display. The Sharp 96×96
display BoosterPack plug-in module does not support touch or color, it is a simple monochrome LCD. It is
a great LCD for ultra-low power display applications and has a unique mirrored pixel display.
This demo cycles screens without user interaction to show simple graphics primitives.

• Lines
• Circles
• Rectangles
• Text
• Images
This demo introduces the functions to configure grlib such as initialization, color inversion, and using
foreground and background colors properly.
3.4 BOOSTXL-BATPAKMKII_FuelGauge_MSP432P401R
This section describes the functionality and structure of the BOOSTXL-
BATPAKMKII_FuelGauge_MSP432P401R demo that is included in the SimpleLink MSP432 SDK (see
Section 4.3).
3.4.1 Source File Structure
The project is split into multiple files (see Table 6). This makes it easier to navigate and reuse parts of it
for other projects.
