The objective of this guide is to explain the high-level software flow for platform development with the TUSS4440 and TUSS4470 devices using serial peripheral interface (SPI), general-purpose input/output (GPIO), and analog-to-digital converter (ADC) commands. This document contains a software development flow-chart, main executable routines, and source code examples. The example software is written in Energia for the MSP-EXP430F5529LP, but can be adapted to any TI LaunchPad™ development kit.
