What is xTaskCreate?
What is xTaskCreate?
xTaskCreate() can only be used to create a task that has unrestricted access to the entire microcontroller memory map. Systems that include MPU support can alternatively create an MPU constrained task using xTaskCreateRestricted(). pvTaskCode. Pointer to the task entry function.
How do I create a free task in RTOS?
Create a new task and add it to the list of tasks that are ready to run. configSUPPORT_DYNAMIC_ALLOCATION must be set to 1 in FreeRTOSConfig. h, or left undefined (in which case it will default to 1), for this RTOS API function to be available.
What is Task handle FreeRTOS?
The task handle is just a pointer to the TCB of the task – but outside of tasks. c the type is hidden as a void*. Each task is also allocated a number.
What is TaskHandle_t?
TaskHandle_t. Type by which tasks are referenced. For example, a call to xTaskCreate returns (via a pointer parameter) an TaskHandle_t variable that can then be used as a parameter to vTaskDelete to delete the task.
How is RTOS different from other OS?
Main Differences Between RTOS and OS RTOS is user and commands specific whereas an OS is generally used by everyone for daily processes. An RTOS uses a sophisticated scheduling algorithm, whereas a regular OS uses a standard approach to solve tasks sequentially.
What is portTICK_PERIOD_MS?
The constant portTICK_PERIOD_MS can be used to calculate real time from the tick rate – with the resolution of one tick period. vTaskDelay() specifies a time at which the task wishes to unblock relative to the time at which vTaskDelay() is called.
What is the purpose of the block time during xQueueReceive ()?
xQueueReceive() blocks endlessly If the tick stops then you will not unblock. By setting the time out to null do you mean setting it to zero? This will prevent the task from blocking at all and in effect cause you to poll the queue.
