/****************************************************************************** | |
* 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, standard FreeRTOS hook functions, and the ISR hander called | |
* by the RTOS after interrupt entry (including nesting) has been taken care of. | |
* | |
* ENSURE TO READ THE DOCUMENTATION PAGE FOR THIS PORT AND DEMO APPLICATION ON | |
* THE http://www.FreeRTOS.org WEB SITE FOR FULL INFORMATION ON USING THIS DEMO | |
* APPLICATION, AND ITS ASSOCIATE FreeRTOS ARCHITECTURE PORT! | |
