/****************************************************************************** | |
* 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 FreeRTOS hook functions. | |
* | |
* This project does not provide an example of how to write an RTOS compatible | |
* interrupt service routine (other than the tick interrupt itself), so this | |
* file contains the function vAnExampleISR_C_Handler() as a dummy example (that | |
* is not actually installed) that can be used as a reference. Also see the | |
* file ExampleISR.s87, and the documentation page for this demo on the | |
* FreeRTOS.org website for full instructions. | |
* | |
* 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! | |
