我只接受ID：  00 00 04 9F
的数据

      CAN_FilterInitStructure.CAN_FilterNumber=0;
      CAN_FilterInitStructure.CAN_FilterMode=CAN_FilterMode_IdList;
      CAN_FilterInitStructure.CAN_FilterScale=CAN_FilterScale_32bit;
      CAN_FilterInitStructure.CAN_FilterIdHigh=0x049F;
      CAN_FilterInitStructure.CAN_FilterIdLow=0x0000;
      CAN_FilterInitStructure.CAN_FilterMaskIdHigh=0x0000;
      CAN_FilterInitStructure.CAN_FilterMaskIdLow=0x0000;
      CAN_FilterInitStructure.CAN_FilterFIFOAssignment=CAN_Filter_FIFO0;
      CAN_FilterInitStructure.CAN_FilterActivation=ENABLE;

      CAN_FilterInit(&CAN_FilterInitStructure);

上面这样接收不到，应该怎么改？

CAN_FilterInitStructure.CAN_FilterNumber=0;
      CAN_FilterInitStructure.CAN_FilterMode=CAN_FilterMode_IdList;
      CAN_FilterInitStructure.CAN_FilterScale=CAN_FilterScale_32bit;
      CAN_FilterInitStructure.CAN_FilterIdHigh=(0x049F<<5);
      CAN_FilterInitStructure.CAN_FilterIdLow=0x0000;
      CAN_FilterInitStructure.CAN_FilterMaskIdHigh=0x0000;
      CAN_FilterInitStructure.CAN_FilterMaskIdLow=0x0000;
      CAN_FilterInitStructure.CAN_FilterFIFOAssignment=CAN_Filter_FIFO0;
      CAN_FilterInitStructure.CAN_FilterActivation=ENABLE;

      CAN_FilterInit(&CAN_FilterInitStructure);
