Its main function is to check that all the + * standard demo tasks are still operational. If everything is running as + * expected then the check task will toggle an LED every 3 seconds. An error + * being discovered in any task will cause the toggle rate to increase to 500ms. + * + * "Reg test" tasks - These fill the registers with known values, then check + * that each register still contains its expected value. Each task uses + * different values. The tasks run with very low priority so get preempted very + * frequently. A register containing an unexpected value is indicative of an + * error in the context switching mechanism. + * + */ + +/* Standard include files. */ +#include +#include + +/* Scheduler include files. */ +#include "FreeRTOS.h" +#include "task.h" + +/* Demo file headers. */ +#include +#include "BlockQ.h" +#include "death.h" +#include "flash.h" +#include "partest.h" +#include "semtest.h" +#include "PollQ.h" +#include "GenQTest.h" +#include "QPeek.h" +#include "recmutex.h" +#include "comtest2.h" + +/* + * Priority definitions for most of the tasks in the demo application.
