71 * This project provides two demo applications. A simple blinky style project,
\r
72 * and a more comprehensive test and demo application. The
\r
73 * mainCREATE_SIMPLE_BLINKY_DEMO_ONLY setting (defined in this file) is used to
\r
74 * select between the two. The simply blinky demo is implemented and described
\r
75 * in main_blinky.c. The more comprehensive test and demo application is
\r
76 * implemented and described in main_full.c.
\r
78 * This file implements the code that is not demo specific, including the
\r
79 * hardware setup, standard FreeRTOS hook functions, and the ISR hander called
\r
80 * by the RTOS after interrupt entry (including nesting) has been taken care of.
\r
82 * ENSURE TO READ THE DOCUMENTATION PAGE FOR THIS PORT AND DEMO APPLICATION ON
