-/* ****************************************************************************\r
- * This project includes a lot of tasks and tests and is therefore complex.\r
- * If you would prefer a much simpler project to get started with then select\r
- * the 'Blinky' build configuration within the HEW IDE. The Blinky \r
- * configuration builds main-blinky.c in place of this file.\r
- * ****************************************************************************\r
- *\r
- * Creates all the demo application tasks, then starts the scheduler. The web\r
- * documentation provides more details of the standard demo application tasks,\r
- * which provide no particular functionality but do provide a good example of\r
- * how to use the FreeRTOS API. The tasks defined in flop.c are included in the\r
- * set of standard demo tasks to ensure the floating point unit gets some\r
- * exercise.\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
- * Webserver ("uIP") task - This serves a number of dynamically generated WEB\r
- * pages to a standard WEB browser. The IP and MAC addresses are configured by\r
- * constants defined at the bottom of FreeRTOSConfig.h. Use either a standard\r
- * Ethernet cable to connect through a hug, or a cross over (point to point)\r
- * cable to connect directly. Ensure the IP address used is compatible with the\r
- * IP address of the machine running the browser - the easiest way to achieve\r
- * this is to ensure the first three octets of the IP addresses are the same.\r
- *\r
- * "Reg test" tasks - These fill the registers with known values, then check\r
- * that each register still contains its expected value. Each task uses\r
- * different values. The tasks run with very low priority so get preempted\r
- * very frequently. A check variable is incremented on each iteration of the\r
- * test loop. A register containing an unexpected value is indicative of an\r
- * error in the context switching mechanism and will result in a branch to a\r
- * null loop - which in turn will prevent the check variable from incrementing\r
- * any further and allow the check task (described below) to determine that an\r
- * error has occurred. The nature of the reg test tasks necessitates that they\r
- * are written in assembly code.\r
- *\r
- * "Check" timer - The check software timer period is initially set to five\r
- * seconds. The callback function associated with the check software timer\r
- * checks that all the standard demo tasks, and the register check tasks, are\r
- * not only still executing, but are executing without reporting any errors. If\r
- * the check software timer discovers that a task has either stalled, or\r
- * reported an error, then it changes its own execution period from the initial\r
- * five seconds, to just 200ms. The check software timer callback function\r
- * also toggles LED3 each time it is called. This provides a visual indication \r
- * of the system status: If LED3 toggles every five seconds, then no issues \r
- * have been discovered. If the LED toggles every 200ms, then an issue has been \r
- * discovered with at least one task.\r
- *\r
- * "High frequency timer test" - A high frequency periodic interrupt is\r
- * generated using a timer - the interrupt is assigned a priority above\r
- * configMAX_SYSCALL_INTERRUPT_PRIORITY so should not be effected by anything\r
- * the kernel is doing. The frequency and priority of the interrupt, in\r
- * combination with other standard tests executed in this demo, should result\r
- * in interrupts nesting at least 3 and probably 4 deep. This test is only\r
- * included in build configurations that have the optimiser switched on. In\r
- * optimised builds the count of high frequency ticks is used as the time base\r
- * for the run time stats.\r
- *\r
- * *NOTE 1* If LED3 is toggling every 5 seconds then all the demo application\r
- * tasks are executing as expected and no errors have been reported in any\r
- * tasks. The toggle rate increasing to 200ms indicates that at least one task\r
- * has reported unexpected behaviour.\r
- *\r
- * *NOTE 2* vApplicationSetupTimerInterrupt() is called by the kernel to let\r
- * the application set up a timer to generate the tick interrupt. In this\r
- * example a compare match timer is used for this purpose.\r
- *\r
- * *NOTE 3* The CPU must be in Supervisor mode when the scheduler is started.\r
- * The PowerON_Reset_PC() supplied in resetprg.c with this demo has\r
- * Change_PSW_PM_to_UserMode() commented out to ensure this is the case.\r
- *\r
- * *NOTE 4* The IntQueue common demo tasks test interrupt nesting and make use\r
- * of all the 8bit timers (as two cascaded 16bit units).\r
