*********************************************************************************************************
*                                        STARTUP TASK
*
* Description : This is an example of a startup task.  As mentioned in the book's text, you MUST
*             initialize the ticker only once multitasking has started.
*
* Arguments : p_arg is the argument passed to 'AppTaskStart()' by 'OSTaskCreate()'.
*
* Returns    : none
*
* Notes    : 1) The first line of code is used to prevent a compiler warning because 'p_arg' is not
*                used.  The compiler should not generate any code for this statement.
