请版主帮忙分析CAN的中断初始化，谢谢。

CAN的那部分怎么没有贴出来？

另外：
void NVIC_Configuration(void)
{
  NVIC_InitTypeDef NVIC_InitStructure;
  
#ifdef  VECT_TAB_RAM  
  /* Set the Vector Table base location at 0x20000000 */
  NVIC_SetVectorTable(NVIC_VectTab_RAM, 0x0);
#else  /* VECT_TAB_FLASH  */
  /* Set the Vector Table base location at 0x08000000 */
  NVIC_SetVectorTable(NVIC_VectTab_FLASH, 0x0);   
#endif
  /* Configure one bit for preemption priority */
  NVIC_PriorityGroupConfig(NVIC_PriorityGroup_2);  
添加上面这一行。

  CAN_FilterInit(&CAN_FilterInitStructure);
  /* CAN FIFO0 message pending interrupt enable */
  CAN_ITConfig(CAN_IT_FMP0, ENABLE);
  /* transmit 1 message */
  TxMessage.StdId=0x12;
  TxMessage.ExtId=0x34;
  TxMessage.IDE=CAN_ID_EXT;
  TxMessage.RTR=CAN_RTR_DATA;
  TxMessage.DLC=2;
  TxMessage.Data[0]=0xDE;
  TxMessage.Data[1]=0xCA;
  CAN_Transmit(&TxMessage);
  /* initialize the value that will be returned */
  ret=0xFF;
      
  /* receive message with interrupt handling */
  i=0;
  while((ret==0xFF)&&(i<0XFFF))
    i++;
  if (i==0xFFF)
   ret=0;  
  /* disable interrupt handling */
  CAN_ITConfig(CAN_IT_FMP0, DISABLE);
  return (TestStatus)ret;

                                 请问CAN的代码是在同一个函数里的，还是不同的函数里的，贴出时将函数完整贴出。
