请帮忙解读一段程序，c语言，uc/os-2

Posted 2023-05-10

int main (void)

OSInit();
OSTaskCreateExt(TASK0,
(void *)0,
&TASK0_STACK[TASK0_STACK_SIZE-1],
TASK0_PRIO,
TASK0_ID,
&TASK0_STACK[0],
TASK0_STACK_SIZE,
(void *)0,
OS_TASK_OPT_STK_CHK | OS_TASK_OPT_STK_CLR);
OSStart();


void TASK0 (void *pdata)

pdata = pdata;
#if OS_CRITICAL_METHOD == 3 // Allocate storage for CPU status register
OS_CPU_SR cpu_sr;
#endif
TargetInit();

BUZZER_Set();
OSTimeDly(OS_TICKS_PER_SEC/10);
BUZZER_Clr();
OSTimeDly(OS_TICKS_PER_SEC/10);

BUZZER_Set();
OSTimeDly(OS_TICKS_PER_SEC/10);
BUZZER_Clr();
OSTimeDly(OS_TICKS_PER_SEC/5);

OSTaskCreateExt(TaskRcv,
(void *)0,
&TaskRcv_STACK[TaskRcv_STACK_SIZE-1],
TaskRcv_PRIO,
TaskRcv_ID,
&TaskRcv_STACK[0],
TaskRcv_STACK_SIZE,
(void *)0,
OS_TASK_OPT_STK_CHK | OS_TASK_OPT_STK_CLR);
OSTaskCreateExt(TaskGPRS,
(void *)0,
&TaskGPRS_STACK[TaskGPRS_STACK_SIZE-1],
TaskGPRS_PRIO,
TaskGPRS_ID,
&TaskGPRS_STACK[0],
TaskGPRS_STACK_SIZE,
(void *)0,
OS_TASK_OPT_STK_CHK | OS_TASK_OPT_STK_CLR);

OSTaskCreateExt(TaskGPS,
(void *)0,
&TaskGPS_STACK[TaskGPS_STACK_SIZE-1],
TaskGPS_PRIO,
TaskGPS_ID,
&TaskGPS_STACK[0],
TaskGPS_STACK_SIZE,
(void *)0,
OS_TASK_OPT_STK_CHK | OS_TASK_OPT_STK_CLR);
while (1)

OSTimeDly(OS_TICKS_PER_SEC*5);

参考技术A main里面创建了一个TASK0任务，然后启动TASK0任务，，在该任务中，先初始化，然后蜂鸣器叫几下，然后创建TaskRcv、TaskGPRS、TaskGPS三个任务，然后进入while循环
