This file implements the simply blinky style version. + * + * NOTE 2: This file only contains the source code that is specific to the + * basic demo.

Once the value is sent, the task loops + * back around to block for another 1000 milliseconds...and so on. + * + * The Queue Receive Task: + * The queue receive task is implemented by the prvQueueReceiveTask() function + * in this file. prvQueueReceiveTask() sits in a loop where it repeatedly + * blocks on attempts to read data from the queue that was created within + * main_blinky(). When data is received, the task checks the value of the + * data, and if the value equals the expected 100, writes 'Blink' to the UART + * (the UART is used in place of the LED to allow easy execution in QEMU). The + * 'block time' parameter passed to the queue receive function specifies that + * the task should be held in the Blocked state indefinitely to wait for data to + * be available on the queue. The queue receive task will only leave the + * Blocked state when the queue send task writes to the queue. As the queue + * send task writes to the queue every 1000 milliseconds, the queue receive + * task leaves the Blocked state every 1000 milliseconds, and therefore toggles + * the LED every 200 milliseconds. + */ + +/* Standard includes. */ +#include +#include +#include + +/* Kernel includes. */ +#include "FreeRTOS.h" +#include "task.h" +#include "queue.h" + +/* Priorities used by the tasks. */ +#define mainQUEUE_RECEIVE_TASK_PRIORITY ( tskIDLE_PRIORITY + 2 ) +#define mainQUEUE_SEND_TASK_PRIORITY ( tskIDLE_PRIORITY + 1 ) + +/* The rate at which data is sent to the queue.

A register + * containing an unexpected value is indicative of an error in the context + * switching mechanism. + * + * "Check" task - The check executes every five seconds. It checks that all + * the standard demo tasks, and the register check tasks, are not only still + * executing, but are executing without reporting any errors.
