97 * This project provides two demo applications. A simple blinky style project,
\r
98 * and a more comprehensive test and demo application. The
\r
99 * mainCREATE_SIMPLE_BLINKY_DEMO_ONLY setting (defined in this file) is used to
\r
100 * select between the two. The simply blinky demo is implemented and described
\r
101 * in main_blinky.c. The more comprehensive test and demo application is
\r
102 * implemented and described in main_full.c.
\r
104 * This file implements the code that is not demo specific, including the

105 * hardware setup and FreeRTOS hook functions.
