-/******************************************************************************\r
- * This project provides two demo applications. A simple blinky style project,\r
- * and a more comprehensive test and demo application. The\r
- * mainCREATE_SIMPLE_BLINKY_DEMO_ONLY setting (defined in this file) is used to\r
- * select between the two. The simply blinky demo is implemented and described\r
- * in main_blinky.c. The more comprehensive test and demo application is\r
- * implemented and described in main_full.c.\r
- *\r
- * This file implements the code that is not demo specific, including the\r
- * hardware setup and FreeRTOS hook functions.\r
- *\r
- * This project does not provide an example of how to write an RTOS compatible\r
- * interrupt service routine (other than the tick interrupt itself), so this\r
- * file contains the function vAnExampleISR_C_Handler() as a dummy example (that\r
- * is not actually installed) that can be used as a reference. Also see the\r
- * file ExampleISR.S, and the documentation page for this demo on the\r
- * FreeRTOS.org website for full instructions.\r
- *\r
- * ENSURE TO READ THE DOCUMENTATION PAGE FOR THIS PORT AND DEMO APPLICATION ON\r
- * THE http://www.FreeRTOS.org WEB SITE FOR FULL INFORMATION ON USING THIS DEMO\r
- * APPLICATION, AND ITS ASSOCIATE FreeRTOS ARCHITECTURE PORT!\r
