请问在uc/OS 中该如何应用函数OSTimeDly ()。
下面是我的源程序，在运行的过程中，运行到OSTimeDly (1)中就在OS_TaskIdle (void *pdata)函数中式循环，不能返回 ，请问是怎么回事啊？
#define LED0_ON WrPortI(PDB0R, NULL, 0);
#define LED0_OFF WrPortI(PDB0R, NULL,1);
#define LED3_ON WrPortI(PDB2R, NULL, 0);
#define LED3_OFF WrPortI(PDB2R, NULL, 1<<2);
void task0(void *data) ;
void task1(void *data) ;
void msDelay(unsigned int delay) ;
OS_STK TaskStk1[100];
OS_STK TaskStk0[100];
main()
{
WrPortI(PDDDR, &PDDDRShadow, 0x07);
WrPortI(PDDR, &PDDRShadow, 0x07);
OSInit();
OSTaskCreate (task1,(void*)0,&TaskStk1[99],4);
OSTaskCreate (task0,(void*)0,&TaskStk0[99],5);
OSStart();
}
void task0(void*data)
{
INT16U i;
BOOLEAN LED0_state;
i=0;
data=data;
LED0_state=TRUE;
//LED3_ON;
while(1)
{
if(LED0_state==FALSE)
{
LED0_state=TRUE;
LED0_OFF;
printf("LCALL TASK0 %d
",i++);
}
else
{
LED0_state=FALSE;
LED0_ON;
printf("LCALL TASK0 %d
",i++);
}
//msDelay(500);
OSTimeDly (1);
}
}
void task1(void*data)
{
INT16U j;
BOOLEAN LED3_state;
j=0;
data=data;
LED3_state=TRUE;
//LED3_ON;
while(1)
{
if(LED3_state==FALSE)
{
LED3_state=TRUE;
LED3_OFF;
printf("LCALL TASK1 %d
",j++);
}
else
{
LED3_state=FALSE;
LED3_ON;
printf("LCALL TASK1 %d
",j++);
}
//msDelay(500);
OSTimeDly (1);
