各位 我的 ucos 中断一直进不去  


static
void
BSP_IntHandler (CPU_DATA
int_id)
{
#if (CPU_CFG_CRITICAL_METHOD == CPU_CRITICAL_METHOD_STATUS_LOCAL)

CPU_SR
cpu_sr;
#endif

CPU_FNCT_VOID
isr;



CPU_CRITICAL_ENTER();
/* Tell uC/OS-II that we are starting an ISR
*/

OSIntNesting++;

CPU_CRITICAL_EXIT();

if (int_id < BSP_INT_SRC_NBR) {

isr = BSP_IntVectTbl[int_id];
        if (isr != (CPU_FNCT_VOID)0) {

isr();

}

}


OSIntExit();
/* Tell uC/OS-II that we are leaving the ISR
*/
}

j-link调试 到了红色的一直不成立  进不了isr();函数.

下面是我的配置.

void time2_Init(void)
{

TIM_TimeBaseInitTypeDef
TIM_TimeBaseStructure;
// TIM_OCInitTypeDef
TIM_OCInitStructure;

NVIC_InitTypeDef NVIC_InitStructure;

RCC_APB1PeriphClockCmd(RCC_APB1Periph_TIM2, ENABLE);

/* enabling interrupt */

NVIC_InitStructure.NVIC_IRQChannel=TIM2_IRQChannel;

NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 1;

NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0;

NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;

NVIC_Init(&NVIC_InitStructure);


/* Time base configuration */

TIM_TimeBaseStructure.TIM_Period = 8000;

TIM_TimeBaseStructure.TIM_Prescaler =50000;

TIM_TimeBaseStructure.TIM_ClockDivision = 0x0;

TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up;

TIM_TimeBaseInit(TIM2, &TIM_TimeBaseStructure);


TIM_ARRPreloadConfig(TIM2,DISABLE);

/* only counter overflow/underflow generate U interrupt */

TIM_UpdateRequestConfig(TIM2,TIM_UpdateSource_Regular);


/* TIM IT enable */

TIM_ITConfig(TIM2,TIM_IT_Update, ENABLE);


/* TIM2 enable counter */

TIM_Cmd(TIM2, ENABLE);
  

BSP_IntVectSet (BSP_INT_ID_TIM2,timer_24);

BSP_IntEn (BSP_INT_ID_TIM2);
}

这是中断服务程序

void timer_24(void)
{
if (TIM_GetITStatus(TIM2, TIM_IT_Update) != RESET)
  {
    TIM_ClearITPendingBit(TIM2, TIM_IT_Update);
    BSP_LED_On(0);
    OSTaskDel(APP_TASK_KBD_PRIO);
  }
}

请各位帮忙看看 .

                                 解决了  呵呵  进是进去了  但是中断标志清不了？   一直进中断 系统挂了

void timer_24(void)
{
if (TIM_GetITStatus(TIM2, TIM_IT_Update) != RESET)
  {
   
   // BSP_LED_On(0);
  //  OSTaskDel(APP_TASK_KBD_PRIO);
    TIM_ClearITPendingBit(TIM2, TIM_IT_Update);
   // BSP_IntClr (BSP_INT_ID_TIM2);
  }
}

                                 服务程序 是这么写的 不知有什么问题没？
