3.2.1 Source File Structure

The project is split into multiple files (see Table 7). This makes it easier to navigate and reuse parts of it for other projects.

Table 7. Source File and Folders

Name Description
main.c The Blink LED main function
Library: Driverlib Device driver library

The main code uses the MSP430 Driver Library to halt the watchdog timer and to configure and toggle the P1.0 GPIO pin connected to the LED inside a software loop.
