See the RTOS Configuration documentation 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. Parameters: xTask  Handle to the task for which the priority is being set. Passing a NULL handle results in the priority of the calling task being set. uxNewPriority  The priority to which the task will be set. Example usage: 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 ); } [ Back to the top ]    [ About FreeRTOS ]    [ Privacy ]    [ Sitemap ]    [ ] Copyright (C) Amazon Web Services, Inc. or its affiliates.
