A simple blinky + * style project, and a more comprehensive test and demo application. The + * mainCREATE_SIMPLE_BLINKY_DEMO_ONLY setting in main.c is used to select + * between the two. See the notes on using mainCREATE_SIMPLE_BLINKY_DEMO_ONLY + * in main.c. This file implements the simply blinky style version. + * + * NOTE 2: This file only contains the source code that is specific to the + * basic demo. Generic functions, such FreeRTOS hook functions, and functions + * required to configure the hardware are defined in main.c. + ****************************************************************************** + * + * main_blinky() creates one queue, and two tasks. It then starts the + * scheduler. + * + * The Queue Send Task: + * The queue send task is implemented by the prvQueueSendTask() function in + * this file. prvQueueSendTask() sits in a loop that causes it to repeatedly + * block for 200 milliseconds, before sending the value 100 to the queue that + * was created within main_blinky(). Once the value is sent, the task loops + * back around to block for another 200 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, toggles an LED. 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 200 milliseconds, the queue receive + * task leaves the Blocked state every 200 milliseconds, and therefore toggles + * the LED every 200 milliseconds. + */ + +/* Kernel includes. */ +#include "FreeRTOS.h" +#include "task.h" +#include "semphr.h" + +/* Standard demo includes. */ +#include "partest.h" + +/* Priorities at which the tasks are created. */ +#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.

The web documentation provides more details of the + * standard demo application tasks, which provide no particular functionality, + * but do provide a good example of how to use the FreeRTOS API. + * + * In addition to the standard demo tasks, the following tasks and tests are + * defined and/or created within this file: + * + * FreeRTOS+CLI command console. The command console is access through the + * UART to USB connector on the ZC702 Zynq development board (marked J2). For + * reasons of robustness testing the UART driver is deliberately written to be + * inefficient and should not be used as a template for a production driver. + * Type "help" to see a list of registered commands.

The default baud rate is 115200. + * + * "Reg test" tasks - These fill both the core and floating point registers with + * known values, then check that each register maintains its expected value for + * the lifetime of the task. Each task uses a different set of values. The reg + * test tasks execute with a very low priority, so get preempted very + * frequently. A register containing an unexpected value is indicative of an + * error in the context switching mechanism. + * + * "Check" task - The check task period is initially set to three seconds. The + * task checks that all the standard demo tasks, and the register check tasks, + * are not only still executing, but are executing without reporting any errors. + * If the check task discovers that a task has either stalled, or reported an + * error, then it changes its own execution period from the initial three + * seconds, to just 200ms. The check task also toggles an LED each time it is + * called. This provides a visual indication of the system status: If the LED + * toggles every three seconds, then no issues have been discovered.
