See the RTOS Configuration documentation 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. Parameters: xTaskToSuspend  Handle to the task being suspended. Passing a NULL handle will cause the calling task to be suspended. 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 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. } [ Back to the top ]    [ About FreeRTOS ]    [ Privacy ]    [ Sitemap ]    [ Report an error on this page ] Copyright (C) Amazon Web Services, Inc. or its affiliates.
