CAN_FilterInitStructure.CAN_FilterIdHigh=0x0A00;//<<8;//接收ID为0x0A的数据
CAN_FilterInitStructure.CAN_FilterIdLow=0x0000;

CAN_FilterInit(&CAN_FilterInitStructure);
使用上面的设置后,CAN 就接收不到数据了,
CAN_FilterInitStructure.CAN_FilterIdHigh=0x0000;//<<8;//接收ID为0x0A的数据
CAN_FilterInitStructure.CAN_FilterIdLow=0x0000;
CAN_FilterInitStructure.CAN_FilterMaskIdHigh=0x0000;//<<8;
CAN_FilterInitStructure.CAN_FilterMaskIdLow=0x0000;
使用上面的设置,然后用地址判断 能接收到数据。
