+ * 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 is used to select between the two. \r
+ * The simply blinky demo is implemented and described in main_blinky.c. The \r
+ * more comprehensive test and demo application is implemented and described in \r
+ * 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
*******************************************************************************\r
* -NOTE- The Win32 port is a simulation (or is that emulation?) only! Do not\r
* expect to get real time behaviour from the Win32 port or this demo\r
* - READ THE WEB DOCUMENTATION FOR THIS PORT FOR MORE INFORMATION ON USING IT -\r
*******************************************************************************\r
*\r
- * main() creates all the demo application tasks, then starts the scheduler. \r
- * The web documentation provides more details of the standard demo application \r
- * tasks, which provide no particular functionality but do provide a good \r
- * example of how to use the FreeRTOS API.\r
- *\r
- * In addition to the standard demo tasks, the following tasks and tests are\r
- * defined and/or created within this file:\r
- *\r
- * "Check" task - This only executes every five seconds but has a high priority\r
- * to ensure it gets processor time. Its main function is to check that all the\r
- * standard demo tasks are still operational. While no errors have been\r
- * discovered the check task will print out "OK" and the current simulated tick\r
- * time. If an error is discovered in the execution of a task then the check\r
- * task will print out an appropriate error message.\r

+ * NOTE 1: The Win32 port is a simulation (or is that emulation?) only! Do not\r
+ * expect to get real time behaviour from the Win32 port or this demo\r
+ * application. It is provided as a convenient development and demonstration\r
+ * test bed only. This was tested using Windows XP on a dual core laptop.\r
+ *\r
+ * In this example, one simulated millisecond will take approximately 40ms to\r
+ * execute, and Windows will not be running the FreeRTOS simulator threads\r
+ * continuously, so the timing information in the FreeRTOS+Trace logs have no\r
+ * meaningful units. See the documentation page for the Windows simulator for\r
+ * an explanation of the slow timing:\r
+ * http://www.freertos.org/FreeRTOS-Windows-Simulator-Emulator-for-Visual-Studio-and-Eclipse-MingW.html\r
+ * - READ THE WEB DOCUMENTATION FOR THIS PORT FOR MORE INFORMATION ON USING IT -\r
+ *\r
+ * NOTE 2: This project provides two demo applications. A simple blinky style\r
+ * project, and a more comprehensive test and demo application. The\r
+ * mainCREATE_SIMPLE_BLINKY_DEMO_ONLY setting in main.c is used to select \r
+ * between the two. See the notes on using mainCREATE_SIMPLE_BLINKY_DEMO_ONLY \r
+ * in main.c. This file implements the simply blinky style version.\r
+ *\r
+ * NOTE 3: This file only contains the source code that is specific to the\r
+ * basic demo. Generic functions, such FreeRTOS hook functions, are defined \r
+ * in main.c.\r
+ ******************************************************************************\r
+ *\r
+ * main_blinky() creates one queue, and two tasks. It then starts the\r
+ * scheduler.\r
+ *\r
+ * The Queue Send Task:\r
+ * The queue send task is implemented by the prvQueueSendTask() function in\r
+ * this file. prvQueueSendTask() sits in a loop that causes it to repeatedly\r
+ * block for 200 (simulated as far as the scheduler is concerned, but in\r
+ * reality much longer - see notes above) milliseconds, before sending the \r
+ * value 100 to the queue that was created within main_blinky(). Once the \r
+ * value is sent, the task loops back around to block for another 200 \r
+ * (simulated) milliseconds.\r
+ *\r
+ * The Queue Receive Task:\r
+ * The queue receive task is implemented by the prvQueueReceiveTask() function\r
+ * in this file. prvQueueReceiveTask() sits in a loop where it repeatedly\r
+ * blocks on attempts to read data from the queue that was created within\r
+ * main_blinky(). When data is received, the task checks the value of the\r
+ * data, and if the value equals the expected 100, outputs a message. The \r
+ * 'block time' parameter passed to the queue receive function specifies that \r
+ * the task should be held in the Blocked state indefinitely to wait for data \r
+ * to be available on the queue. The queue receive task will only leave the\r
+ * Blocked state when the queue send task writes to the queue. As the queue\r
+ * send task writes to the queue every 200 (simulated - see notes above) \r
+ * milliseconds, the queue receive task leaves the Blocked state every 200 \r
+ * milliseconds, and therefore outputs a message every 200 milliseconds.\r
