uCOS-II为什么任务都不运行啊？新手请指教！

gipo设置都没问题，呼吸灯都不亮。

编译器报错了没？？怎么没看见你调用的头函数？？

[juhuanwen]

OSTimeDly(OSmsToTick(500));OSTimeDly(OSmsToTick(1000UL)); 延时是否失效，把延时调大,或者直接换个延时函数看下。 另外在TaskInit函数里面可以加入进入临界区和退出临界区以及挂起起始任务的三个操作例子如下： OS_ENTER_CRITICAL(); //进入临界区(无法被中断打断) OSTaskCreate(adc1_task,(void *)0,(OS_STK*)&ADC1_TASK_STK[ADC1_STK_SIZE-1],ADC1_TASK_PRIO); OSTaskCreate(net_task,(void *)0,(OS_STK*)&NET_TASK_STK[NET_STK_SIZE-1],NET_TASK_PRIO); OSTaskCreate(move_task,(void *)0,(OS_STK*)&MOVE_TASK_STK[MOVE_STK_SIZE-1],MOVE_TASK_PRIO); OSTaskSuspend(START_TASK_PRIO); //挂起起始任务. OS_EXIT_CRITICAL();

[zhujinqiang]

while (1) {
OSTimeDly(OSmsToTick(1000UL));
//     OSSemPend(taskcon,0,&err);
//   UARTSendByte((INT8U)TASK_TEST_ID);
//   OSSemPost(taskcon);
}

任务里面就一直死循环，都不退出啊？
