Getting Started with μC/OS-III
L3-6(1)
Create Task #1 by calling OSTaskCreate() . If this task happens to have a
higher priority than the task that creates it, μC/OS-III will immediately start
Task #1. If the created task has a lower priority, OSTaskCreate() will return to
AppTaskStart() and continue execution.
L3-6(2)
Task #2 is created and if it has a higher priority than AppTaskStart() ,
μC/OS-III will immediately switch to that task.
static void AppTask1 (void *p_arg)
{
OS_ERR err;
CPU_TS ts;
p_arg = p_arg;
while (1) {
OSTimeDly ((OS_TICK )1,
(OS_OPT )OS_OPT_TIME_DLY,
(OS_ERR *)&err);
OSQPost ((OS_Q *)&AppQ,
(void *)1;
(OS_MSG_SIZE)sizeof(void *),
(OS_OPT )OS_OPT_POST_FIFO,
(OS_ERR *)&err);
OSMutexPend((OS_MUTEX *)&AppMutex,
(OS_TICK )0,
(OS_OPT )OS_OPT_PEND_BLOCKING;
(CPU_TS *)&ts,
(OS_ERR *)&err);
/* Access shared resource */

OSMutexPost((OS_MUTEX
(OS_OPT
(OS_ERR
*)&AppMutex,
)OS_OPT_POST_NONE,
*)&err);

}
}
Listing 3-7 APP.C (4th Part)
L3-7(1)
The task starts by waiting for one tick to expire before it does anything useful.
If the μC/OS-III tick rate is configured for 1000 Hz, the task will execute every
millisecond.
