vTaskStartScheduler

[RTOS Kernel Control]

task. h

1void vTaskStartScheduler( void );

Starts the RTOS scheduler. After calling the RTOS kernel has control over which tasks are executed and when.

The idle task and optionally the timer daemon task are created automatically when the RTOS scheduler is started.

vTaskStartScheduler()
will only return if there is insufficient RTOS heap available to create the idle or timer daemon tasks.

All the RTOS demo application projects contain examples of using 

vTaskStartScheduler()
, normally in the 
main()
function within main.c.

Example usage:

1void vAFunction( void )
2{
3    // Tasks can be created before or after starting the RTOS scheduler
4    xTaskCreate( vTaskCode,
5                 "NAME",
6                 STACK_SIZE,
7                 NULL,
8                 tskIDLE_PRIORITY,
9                 NULL );
10

11    // Start the real time scheduler.
12    vTaskStartScheduler();
13

14    // Will not get here unless there is insufficient RAM.
