说的还是挺不错的

can的例子一直没有搞，可以参考官方固件库库V1.4.0里面的例子。

}



void CAN_NVIC(void)
{
  NVIC_InitTypeDef  NVIC_InitStructure;
  NVIC_InitStructure.NVIC_IRQChannel = CAN1_RX0_IRQn;
  NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0x0;

  NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
  NVIC_Init(&NVIC_InitStructure);
  
}


void CAN1_RX0_IRQHandler(void)
{
  CanRxMsg RxMessage;
  CAN_Receive(CAN1, CAN_FIFO0, &RxMessage);
    int yuan_Number = RxMessage.Data[0];
}


我这样配置完，能不能收到数据？有没有错误的地方
