xTaskGenericNotify() function
task. h @code{c} BaseType_t xTaskNotifyIndexed( TaskHandle_t xTaskToNotify, UBaseType_t uxIndexToNotify, uint32_t ulValue, eNotifyAction eAction ); BaseType_t xTaskNotify( TaskHandle_t xTaskToNotify, uint32_t ulValue, eNotifyAction eAction ); @endcode See https://www.FreeRTOS.org/RTOS-task-notifications.html for details. configUSE_TASK_NOTIFICATIONS must be undefined or defined as 1 for these functions to be available. Sends a direct to task notification to a task, with an optional value and action. Each task has a private array of "notification values" (or 'notifications'), each of which is a 32-bit unsigned integer (uint32_t). The constant configTASK_NOTIFICATION_ARRAY_ENTRIES sets the number of indexes in the array, and (for backward compatibility) defaults to 1 if left undefined. Prior to FreeRTOS V10.4.0 there was only one notification value per task. Events can be sent to a task using an intermediary object. Examples of such objects are queues, semaphores, mutexes and event groups. Task notifications are a method of sending an event directly to a task without the need for such an intermediary object. A notification sent to a task can optionally perform an action, such as update, overwrite or increment one of the task's notification values. In that way task notifications can be used to send data to a task, or be used as light weight and fast binary or counting semaphores. A task can use xTaskNotifyWaitIndexed() or ulTaskNotifyTakeIndexed() to [optionally] block to wait for a notification to be pending. The task does not consume any CPU time while it is in the Blocked state. A notification sent to a task will remain pending until it is cleared by the task calling xTaskNotifyWaitIndexed() or ulTaskNotifyTakeIndexed() (or their un-indexed equivalents). If the task was already in the Blocked state to wait for a notification when the notification arrives then the task will automatically be removed from the Blocked state (unblocked) and the notification cleared. **NOTE** Each notification within the array operates independently - a task can only block on one notification within the array at a time and will not be unblocked by a notification sent to any other array index. Backward compatibility information: Prior to FreeRTOS V10.4.0 each task had a single "notification value", and all task notification API functions operated on that value. Replacing the single notification value with an array of notification values necessitated a new set of API functions that could address specific notifications within the array. xTaskNotify() is the original API function, and remains backward compatible by always operating on the notification value at index 0 in the array. Calling xTaskNotify() is equivalent to calling xTaskNotifyIndexed() with the uxIndexToNotify parameter set to 0. eSetBits - The target notification value is bitwise ORed with ulValue. xTaskNotifyIndexed() always returns pdPASS in this case. eIncrement - The target notification value is incremented. ulValue is not used and xTaskNotifyIndexed() always returns pdPASS in this case. eSetValueWithOverwrite - The target notification value is set to the value of ulValue, even if the task being notified had not yet processed the previous notification at the same array index (the task already had a notification pending at that index). xTaskNotifyIndexed() always returns pdPASS in this case. eSetValueWithoutOverwrite - If the task being notified did not already have a notification pending at the same array index then the target notification value is set to ulValue and xTaskNotifyIndexed() will return pdPASS. If the task being notified already had a notification pending at the same array index then no action is performed and pdFAIL is returned. eNoAction - The task receives a notification at the specified array index without the notification value at that index being updated. ulValue is not used and xTaskNotifyIndexed() always returns pdPASS in this case. pulPreviousNotificationValue - Can be used to pass out the subject task's notification value before any bits are modified by the notify function.

Description
task. h @code{c} BaseType_t xTaskCreate( TaskFunction_t pxTaskCode, const char * const pcName, const configSTACK_DEPTH_TYPE uxStackDepth, void *pvParameters, UBaseType_t uxPriority, TaskHandle_t *pxCreatedTask ); @endcode Create a new task and add it to the list of tasks that are ready to run. Internally, within the FreeRTOS implementation, tasks use two blocks of memory. The first block is used to hold the task's data structures. The second block is used by the task as its stack. If a task is created using xTaskCreate() then both blocks of memory are automatically dynamically allocated inside the xTaskCreate() function. (see https://www.FreeRTOS.org/a00111.html). If a task is created using xTaskCreateStatic() then the application writer must provide the required memory. xTaskCreateStatic() therefore allows a task to be created without using any dynamic memory allocation. See xTaskCreateStatic() for a version that does not use any dynamic memory allocation. 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(). Example usage: @code{c} // Task to be created. void vTaskCode( void * pvParameters ) { for( ;; ) { // Task code goes here. } } // Function that creates a task. void vOtherFunction( void ) { static uint8_t ucParameterToPass; TaskHandle_t xHandle = NULL; // Create the task, storing the handle. Note that the passed parameter ucParameterToPass // must exist for the lifetime of the task, so in this case is declared static. If it was just an // an automatic stack variable it might no longer exist, or at least have been corrupted, by the time // the new task attempts to access it. xTaskCreate( vTaskCode, "NAME", STACK_SIZE, &ucParameterToPass, tskIDLE_PRIORITY, &xHandle ); configASSERT( xHandle ); // Use the handle to delete the task. if( xHandle != NULL ) { vTaskDelete( xHandle ); } } @endcode
task. h @code{c} void vTaskDelete( TaskHandle_t xTaskToDelete ); @endcode INCLUDE_vTaskDelete must be defined as 1 for this function to be available. See the configuration section for more information. Remove a task from the RTOS real time kernel's management. The task being deleted will be removed from all ready, blocked, suspended and event lists. NOTE: The idle task is responsible for freeing the kernel allocated memory from tasks that have been deleted. It is therefore important that the idle task is not starved of microcontroller processing time if your application makes any calls to vTaskDelete (). Memory allocated by the task code is not automatically freed, and should be freed before the task is deleted. See the demo application file death.c for sample code that utilises vTaskDelete (). Example usage: @code{c} void vOtherFunction( void ) { TaskHandle_t xHandle; // Create the task, storing the handle. xTaskCreate( vTaskCode, "NAME", STACK_SIZE, NULL, tskIDLE_PRIORITY, &xHandle ); // Use the handle to delete the task. vTaskDelete( xHandle ); } @endcode

A version of xTaskNotifyIndexed() that can be used from an interrupt service routine (ISR). Each task has a private array of "notification values" (or 'notifications'), each of which is a 32-bit unsigned integer (uint32_t).

A task can use xTaskNotifyWaitIndexed() to [optionally] block to wait for a notification to be pending, or ulTaskNotifyTakeIndexed() to [optionally] block to wait for a notification value to have a non-zero value. The task does not consume any CPU time while it is in the Blocked state. A notification sent to a task will remain pending until it is cleared by the task calling xTaskNotifyWaitIndexed() or ulTaskNotifyTakeIndexed() (or their un-indexed equivalents). If the task was already in the Blocked state to wait for a notification when the notification arrives then the task will automatically be removed from the Blocked state (unblocked) and the notification cleared. **NOTE** Each notification within the array operates independently - a task can only block on one notification within the array at a time and will not be unblocked by a notification sent to any other array index.

task. h @code{c} BaseType_t xTaskNotifyStateClearIndexed( TaskHandle_t xTask, UBaseType_t uxIndexToCLear ); BaseType_t xTaskNotifyStateClear( TaskHandle_t xTask ); @endcode See https://www.FreeRTOS.org/RTOS-task-notifications.html for details. configUSE_TASK_NOTIFICATIONS must be undefined or defined as 1 for these functions to be available. Each task has a private array of "notification values" (or 'notifications'), each of which is a 32-bit unsigned integer (uint32_t). The constant configTASK_NOTIFICATION_ARRAY_ENTRIES sets the number of indexes in the array, and (for backward compatibility) defaults to 1 if left undefined. Prior to FreeRTOS V10.4.0 there was only one notification value per task. If a notification is sent to an index within the array of notifications then the notification at that index is said to be 'pending' until it is read or explicitly cleared by the receiving task. xTaskNotifyStateClearIndexed() is the function that clears a pending notification without reading the notification value. The notification value at the same array index is not altered. Set xTask to NULL to clear the notification state of the calling task. Backward compatibility information: Prior to FreeRTOS V10.4.0 each task had a single "notification value", and all task notification API functions operated on that value. Replacing the single notification value with an array of notification values necessitated a new set of API functions that could address specific notifications within the array. xTaskNotifyStateClear() is the original API function, and remains backward compatible by always operating on the notification value at index 0 within the array. Calling xTaskNotifyStateClear() is equivalent to calling xTaskNotifyStateClearIndexed() with the uxIndexToNotify parameter set to 0.
task. h @code{c} eTaskState eTaskGetState( TaskHandle_t xTask ); @endcode INCLUDE_eTaskGetState must be defined as 1 for this function to be available. See the configuration section for more information. Obtain the state of any task. States are encoded by the eTaskState enumerated type.
Utility task that simply returns pdTRUE if the task referenced by xTask is currently in the Suspended state, or pdFALSE if the task referenced by xTask is in any other state.

In that way task notifications can be used to send data to a task, or be used as light weight and fast binary or counting semaphores. vTaskNotifyGiveIndexedFromISR() is intended for use when task notifications are used as light weight and faster binary or counting semaphore equivalents. Actual FreeRTOS semaphores are given from an ISR using the xSemaphoreGiveFromISR() API function, the equivalent action that instead uses a task notification is vTaskNotifyGiveIndexedFromISR(). When task notifications are being used as a binary or counting semaphore equivalent then the task being notified should wait for the notification using the ulTaskNotifyTakeIndexed() API function rather than the xTaskNotifyWaitIndexed() API function. **NOTE** Each notification within the array operates independently - a task can only block on one notification within the array at a time and will not be unblocked by a notification sent to any other array index.

See the configuration section for more information. Populates a TaskStatus_t structure with information about a task. Example usage: @code{c} void vAFunction( void ) { TaskHandle_t xHandle; TaskStatus_t xTaskDetails; // Obtain the handle of a task from its name. xHandle = xTaskGetHandle( "Task_Name" ); // Check the handle is not NULL. configASSERT( xHandle ); // Use the handle to obtain further information about the task. vTaskGetInfo( xHandle, &xTaskDetails, pdTRUE, // Include the high water mark in xTaskDetails. eInvalid ); // Include the task state in xTaskDetails. } @endcode

The constant configTASK_NOTIFICATION_ARRAY_ENTRIES sets the number of indexes in the array, and (for backward compatibility) defaults to 1 if left undefined. Prior to FreeRTOS V10.4.0 there was only one notification value per task. ulTaskNotifyValueClearIndexed() clears the bits specified by the ulBitsToClear bit mask in the notification value at array index uxIndexToClear of the task referenced by xTask.

task. h @code{c} UBaseType_t uxTaskPriorityGet( const TaskHandle_t xTask ); @endcode INCLUDE_uxTaskPriorityGet must be defined as 1 for this function to be available. See the configuration section for more information. Obtain the priority of any task. Example usage: @code{c} void vAFunction( void ) { TaskHandle_t xHandle; // Create a task, storing the handle. xTaskCreate( vTaskCode, "NAME", STACK_SIZE, NULL, tskIDLE_PRIORITY, &xHandle ); // ... // Use the handle to obtain the priority of the created task. // It was created with tskIDLE_PRIORITY, but may have changed // it itself. if( uxTaskPriorityGet( xHandle ) != tskIDLE_PRIORITY ) { // The task has changed it's priority. } // ... // Is our priority higher than the created task? if( uxTaskPriorityGet( xHandle ) < uxTaskPriorityGet( NULL ) ) { // Our priority (obtained using NULL handle) is higher. } } @endcode
task. h @code{c} UBaseType_t uxTaskPriorityGetFromISR( const TaskHandle_t xTask ); @endcode A version of uxTaskPriorityGet() that can be used from an ISR.
task. h @code{c} UBaseType_t uxTaskBasePriorityGet( const TaskHandle_t xTask ); @endcode INCLUDE_uxTaskPriorityGet and configUSE_MUTEXES must be defined as 1 for this function to be available. See the configuration section for more information. Obtain the base priority of any task.
task. h @code{c} UBaseType_t uxTaskBasePriorityGetFromISR( const TaskHandle_t xTask ); @endcode A version of uxTaskBasePriorityGet() that can be used from an ISR.
task. h @code{c} void vTaskPrioritySet( TaskHandle_t xTask, UBaseType_t uxNewPriority ); @endcode INCLUDE_vTaskPrioritySet must be defined as 1 for this function to be available. See the configuration section for more information. Set the priority of any task. A context switch will occur before the function returns if the priority being set is higher than the currently executing task. Example usage: @code{c} void vAFunction( void ) { TaskHandle_t xHandle; // Create a task, storing the handle. xTaskCreate( vTaskCode, "NAME", STACK_SIZE, NULL, tskIDLE_PRIORITY, &xHandle ); // ... // Use the handle to raise the priority of the created task. vTaskPrioritySet( xHandle, tskIDLE_PRIORITY + 1 ); // ... // Use a NULL handle to raise our priority to the same value. vTaskPrioritySet( NULL, tskIDLE_PRIORITY + 1 ); } @endcode
task. h @code{c} void vTaskSuspend( TaskHandle_t xTaskToSuspend ); @endcode INCLUDE_vTaskSuspend must be defined as 1 for this function to be available. See the configuration section for more information. Suspend any task. When suspended a task will never get any microcontroller processing time, no matter what its priority. Calls to vTaskSuspend are not accumulative - i.e. calling vTaskSuspend () twice on the same task still only requires one call to vTaskResume () to ready the suspended task. Example usage: @code{c} void vAFunction( void ) { TaskHandle_t xHandle; // Create a task, storing the handle. xTaskCreate( vTaskCode, "NAME", STACK_SIZE, NULL, tskIDLE_PRIORITY, &xHandle ); // ... // Use the handle to suspend the created task. vTaskSuspend( xHandle ); // ... // The created task will not run during this period, unless // another task calls vTaskResume( xHandle ). //... // Suspend ourselves. vTaskSuspend( NULL ); // We cannot get here unless another task calls vTaskResume // with our handle as the parameter. } @endcode
task. h @code{c} void vTaskResume( TaskHandle_t xTaskToResume ); @endcode INCLUDE_vTaskSuspend must be defined as 1 for this function to be available. See the configuration section for more information. Resumes a suspended task. A task that has been suspended by one or more calls to vTaskSuspend () will be made available for running again by a single call to vTaskResume (). Example usage: @code{c} void vAFunction( void ) { TaskHandle_t xHandle; // Create a task, storing the handle. xTaskCreate( vTaskCode, "NAME", STACK_SIZE, NULL, tskIDLE_PRIORITY, &xHandle ); // ... // Use the handle to suspend the created task. vTaskSuspend( xHandle ); // ... // The created task will not run during this period, unless // another task calls vTaskResume( xHandle ). //... // Resume the suspended task ourselves. vTaskResume( xHandle ); // The created task will once again get microcontroller processing // time in accordance with its priority within the system. } @endcode
task. h @code{c} void xTaskResumeFromISR( TaskHandle_t xTaskToResume ); @endcode INCLUDE_xTaskResumeFromISR must be defined as 1 for this function to be available. See the configuration section for more information. An implementation of vTaskResume() that can be called from within an ISR. A task that has been suspended by one or more calls to vTaskSuspend () will be made available for running again by a single call to xTaskResumeFromISR (). xTaskResumeFromISR() should not be used to synchronise a task with an interrupt if there is a chance that the interrupt could arrive prior to the task being suspended - as this can lead to interrupts being missed. Use of a semaphore as a synchronisation mechanism would avoid this eventuality.
task. h @code{c} char *pcTaskGetName( TaskHandle_t xTaskToQuery ); @endcode
task.h @code{c} UBaseType_t uxTaskGetStackHighWaterMark( TaskHandle_t xTask ); @endcode INCLUDE_uxTaskGetStackHighWaterMark must be set to 1 in FreeRTOSConfig.h for this function to be available. Returns the high water mark of the stack associated with xTask. That is, the minimum free stack space there has been (in words, so on a 32 bit machine a value of 1 means 4 bytes) since the task started. The smaller the returned number the closer the task has come to overflowing its stack. uxTaskGetStackHighWaterMark() and uxTaskGetStackHighWaterMark2() are the same except for their return type. Using configSTACK_DEPTH_TYPE allows the user to determine the return type. It gets around the problem of the value overflowing on 8-bit types without breaking backward compatibility for applications that expect an 8-bit return type.
Sets the core affinity mask for a task. It sets the cores on which a task can run. configUSE_CORE_AFFINITY must be defined as 1 for this function to be available. Example usage: // The function that creates task. void vAFunction( void ) { TaskHandle_t xHandle; UBaseType_t uxCoreAffinityMask; // Create a task, storing the handle. xTaskCreate( vTaskCode, "NAME", STACK_SIZE, NULL, tskIDLE_PRIORITY, &( xHandle ) ); // Define the core affinity mask such that this task can only run // on core 0 and core 2. uxCoreAffinityMask = ( ( 1 << 0 ) | ( 1 << 2 ) ); //Set the core affinity mask for the task. vTaskCoreAffinitySet( xHandle, uxCoreAffinityMask ); }
Gets the core affinity mask for a task. configUSE_CORE_AFFINITY must be defined as 1 for this function to be available. Example usage: // Task handle of the networking task - it is populated elsewhere. TaskHandle_t xNetworkingTaskHandle; void vAFunction( void ) { TaskHandle_t xHandle; UBaseType_t uxNetworkingCoreAffinityMask; // Create a task, storing the handle. xTaskCreate( vTaskCode, "NAME", STACK_SIZE, NULL, tskIDLE_PRIORITY, &( xHandle ) ); //Get the core affinity mask for the networking task. uxNetworkingCoreAffinityMask = vTaskCoreAffinityGet( xNetworkingTaskHandle ); // Here is a hypothetical scenario, just for the example. Assume that we // have 2 cores - Core 0 and core 1. We want to pin the application task to // the core different than the networking task to ensure that the // application task does not interfere with networking. if( ( uxNetworkingCoreAffinityMask & ( 1 << 0 ) ) != 0 ) { // The networking task can run on core 0, pin our task to core 1. vTaskCoreAffinitySet( xHandle, ( 1 << 1 ) ); } else { // Otherwise, pin our task to core 0. vTaskCoreAffinitySet( xHandle, ( 1 << 0 ) ); } }
task. h @code{c} BaseType_t xTaskAbortDelay( TaskHandle_t xTask ); @endcode INCLUDE_xTaskAbortDelay must be defined as 1 in FreeRTOSConfig.h for this function to be available. A task will enter the Blocked state when it is waiting for an event. The event it is waiting for can be a temporal event (waiting for a time), such as when vTaskDelay() is called, or an event on an object, such as when xQueueReceive() or ulTaskNotifyTake() is called. If the handle of a task that is in the Blocked state is used in a call to xTaskAbortDelay() then the task will leave the Blocked state, and return from whichever function call placed the task into the Blocked state. There is no 'FromISR' version of this function as an interrupt would need to know which object a task was blocked on in order to know which actions to take. For example, if the task was blocked on a queue the interrupt handler would then need to know if the queue was locked.
