\r
29 * This project provides two demo applications. A simple blinky style project,
\r
30 * and a more comprehensive test and demo application. The
\r
31 * mainCREATE_SIMPLE_BLINKY_DEMO_ONLY setting (defined in this file) is used to
\r
32 * select between the two. The simply blinky demo is implemented and described
\r
33 * in main_blinky.c. The more comprehensive test and demo application is
\r
34 * implemented and described in main_full.c.
\r
36 * This file implements the code that is not demo specific, including the
\r
37 * hardware setup and FreeRTOS hook functions.
\r
39 * ENSURE TO READ THE DOCUMENTATION PAGE FOR THIS PORT AND DEMO APPLICATION ON
\r
40 * THE http://www.FreeRTOS.org WEB SITE FOR FULL INFORMATION ON USING THIS DEMO
\r
41 * APPLICATION, AND ITS ASSOCIATE FreeRTOS ARCHITECTURE PORT!
