*
* 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.
*
* Argument(s) : p_arg is the argument passed to 'App_TaskStart()' by 'OSTaskCreate()'.
*
* Return(s) : none.
*
* Caller(s) : This is a task.
*
* 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.

串口调试只显示任务1和任务2输出的内容，并不进中断，不输出的内容
