我CANH, CANL出来接的是USB-CAN的模块
void CAN_Interrupt_Config(void)
{
CAN_InitTypeDef       CAN_InitStructure;// CAN ÅäÖÃ½á¹¹Ìå

CAN_DeInit(CAN1);//½«ÍâÉèCANµÄÈ«²¿¼Ä´æÆ÷ÖØÉèÎªÈ±Ê¡Öµ

u8 can_tx(u16 Data1)

      u16 i;

  CanTxMsg TxMessage;

  TxMessage.StdId=0x11;
  TxMessage.ExtId=0x0000;
  TxMessage.IDE=CAN_ID_STD;
  TxMessage.RTR=CAN_RTR_DATA;
  TxMessage.DLC=8;
  TxMessage.Data[0]=Data1/256  ;
