- * This project provides two demo applications. A simple blinky style project,
- * and a more comprehensive test and demo application. The
- * mainCREATE_SIMPLE_BLINKY_DEMO_ONLY setting (defined in this file) is used to
- * select between the two. The simply blinky demo is implemented and described
- * in main_blinky.c. The more comprehensive test and demo application is
- * implemented and described in main_full.c.
- *
- * This file implements the code that is not demo specific, including the
- * hardware setup and standard FreeRTOS hook functions.
