RT.现在在做一个小模块.RTC生成时间作为日志的一部分保存在SD卡上.可是...中断好像冲突了.不能1s生成一个文件.1s中断不执行..咋办呢
具体如下:
主函数中
void InterruptConfig(void)
{
  /* Deinitializes the NVIC */
  NVIC_DeInit();

  NVIC_Configuration();

  /* Configure the Priority Group to 2 bits */
//  NVIC_PriorityGroupConfig(NVIC_PriorityGroup_2);               

  /* Configure the SysTick handler priority */
  //为了使用SDIO中断，下面的中断优先级被我改低了
  NVIC_SystemHandlerPriorityConfig(SystemHandler_SysTick, 1, 1);
}



RTC中断如下.为什么就不行了呢...

void RTC_IRQHandler(void)
{
  if(RTC_GetITStatus(RTC_IT_SEC) != RESET)
  {
    /* Clear the RTC Second interrupt */
    RTC_ClearITPendingBit(RTC_IT_SEC);
   
    /* Toggle led connected to PC.06 pin each 1s */
    GPIO_WriteBit(GPIOC, GPIO_Pin_6, (BitAction)(1-GPIO_ReadOutputDataBit(GPIOC, GPIO_Pin_6)));

    /* Enable time update */
    TimeDisplay = 1;

    /* Wait until last write operation on RTC registers has finished */
    RTC_WaitForLastTask();
    /* Reset RTC Counter when Time is 23:59:59 */
    if(RTC_GetCounter() == 0x00015180)
    {
      RTC_SetCounter(0x0);
      /* Wait until last write operation on RTC registers has finished */
      RTC_WaitForLastTask();
    }
  }
