|
|
* @brief
|
|
* This is the header file for the Timer Control component.
|
|
*
|
|
* The timer callback control component provides a mechanism by which different
|
|
* client components can start a timer and have a supplied callback function
|
|
* invoked when the timer expires.
|
|
* The callbacks are all dispatched from one thread inside this component.
|
|
* Any component that needs to be called periodically should use this facility
|
|
* rather than create its own task with a sleep loop.
