原子老师：创建任务的写法有两种写法 是不是等效的呢 ？
一种写法是：
os_err = OSTaskCreate((void (*)(void *)) App_TaskStart, 
                                   ( void             * ) 0,
                                   ( OS_STK        * ) &App_TaskStartStk[APP_TASK_START_STK_SIZE - 1],
                                   ( INT8U             ) APP_TASK_START_PRIO
                                   );
而另一种写法是：
 os_err = OSTaskCreate(App_TaskStart,                             
                                      0,
                                     &App_TaskStartStk[APP_TASK_START_STK_SIZE - 1],
                                     APP_TASK_START_PRIO
                                   );
