ucos, TI, ni, pi, gp
1.首先我建立一个主任务
   static  void  AppTaskStart (void *p_arg)
{
    CPU_INT32U  i;
    CPU_INT32U  j;


   .............

    BSP_Init();                                                 /* 

   ..........
}
2.在BSP_Init(); 函数里我初始化了一个外部中断线
void  BSP_Init (void)
{
   
      ...........

   
      temper_Init();

     ...........
}
函数的操作:
static  void temper_Init(void)

  GPIO_InitTypeDef GPIO_InitStructure;
  EXTI_InitTypeDef EXTI_InitStructure;
  RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOB, ENABLE);
  /* Configure PB.09 as input floating (EXTI Line 9) */
  GPIO_InitStructure.GPIO_Pin = GPIO_Pin_9;
  GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN_FLOATING;
  GPIO_Init(GPIOB, &GPIO_InitStructure);
  
  
  GPIO_EXTILineConfig(GPIO_PortSourceGPIOB, GPIO_PinSource9);

  /* Configure EXTI Line9 to generate an interrupt on falling edge */  
  EXTI_InitStructure.EXTI_Line = EXTI_Line9;
  EXTI_InitStructure.EXTI_Mode = EXTI_Mode_Interrupt;
  EXTI_InitStructure.EXTI_Trigger = EXTI_Trigger_Falling;
  EXTI_InitStructure.EXTI_LineCmd = ENABLE;
  EXTI_Init(&EXTI_InitStructure);
  EXTI_GenerateSWInterrupt(EXTI_Line9);
  
}
这样当我按键时会产生中断。
  我想问的是中断跳到哪个函数去呢,我不知道的就是怎样写这个中断要跳转到的函数(函数名称和定义步骤都不清楚)
    请高手指点

中断跳转到
static  void  App_Spurious_ISR (void) @ "ICODE"
{
    while (1) {
       LED_On(1)  ;
    }
}
我用的EXTI_Line0中断
中断能产生   但是我怎么判断是EXTI_Line0中断呢  有很多中断都跳到这个里面

你再试试

定义一个中断服务程序过程, 定义方法您参考 OSPendSV, Tmr_TickISR_Handler
例:YourExtiLine0_ISR

App_Spurious_ISR,                   /* 22, INTISR[  6]  EXTI Line0 Interrupt                       */
把上面这行改成 
YourExtiLine0_ISR,                   /* 22, INTISR[  6]  EXTI Line0 Interrupt                       */
 
你再试试。

谢谢楼上

但是还有一事不明  
我改了程序
   void  App_Spurious_ISR1 (void) //@ "ICODE"
{   OS_CPU_SR  cpu_sr;


    OS_ENTER_CRITICAL();                                             OSIntNesting++;
    OS_EXIT_CRITICAL();
   
      LED_On(0) ;
      OSIntExit(); 
 
}
可以正常进入 点亮led
  但是为什么一直在里面 退不出去
还有第一次运行 会自己直接进入中断  复位一次就好了

中断退不出来问题找到了

但是为什么一运行 就进入中断呢  复位一次  就没事了了
