1 设备信息public  struct  BOARD_INFO
{public ushort	hw_Version;public ushort fw_Version;public ushort dr_Version;public ushort in_Version;public ushort irq_Num;public byte	can_Num;[MarshalAs(UnmanagedType.ByValArray, SizeConst = 20)]public byte[] str_Serial_Num;[MarshalAs(UnmanagedType.ByValArray, SizeConst =40)]public byte[]	str_hw_Type;[MarshalAs(UnmanagedType.ByValArray, SizeConst = 4)]public ushort[] Reserved;
}2 数据帧对象public struct CAN_OBJ{public uint ID;public uint TimeStamp;public byte TimeFlag;public byte SendType;public byte RemoteFlag;public byte ExternFlag;public byte DataLen;[MarshalAs(UnmanagedType.ByValArray, SizeConst = 8)]public byte[] data;[MarshalAs(UnmanagedType.ByValArray, SizeConst = 3)]public byte[] Reserved;
}3 CAN通道状态
public struct CAN_STATUS
{ public uchar ErrInterrupt; //中断记录，读操作会清除。public uchar regMode;      //CAN控制器模式寄存器。public uchar regStatus;    //CAN控制器状态寄存器。public uchar regALCapture; //CAN控制器仲裁丢失寄存器。public uchar regECCapture; //CAN控制器错误寄存器。public uchar regEWLimit;   //CAN控制器错误警告限制寄存器。public uchar regRECounter; //CAN控制器接收错误寄存器。public uchar regTECounter; //CAN控制器发送错误寄存器。public int   Reserved; 
}4 错误信息
public struct ERR_INFO
{ public UINT32 ErrCode;         //错误码。public byte Passive_ErrData[3];//消极错误public byte ArLost_ErrData;    //仲裁丢失错误
}5 设备配置参数
public struct INIT_CONFIG
{public uint AccCode;    //【左对齐】帧id的bit完全匹配才接收public uint AccMask;    //【左对齐】帧id的bit【1】为失效AccCodepublic uint Reserved;   //保留public byte Filter;     //滤帧使能。【0】不使能，【1】使能。public byte Timing0;    //波特率 1MHz【t0=0x00，t1=0x14】public byte Timing1;    //波特率public byte Mode;       //模式。【0】正常收发【1】只收【2】环回
}6 FILTER_RECORD
public struct FILTER_RECORD
{ public UInt32 ExtFrame; //过滤的帧类型【0】只收标准帧【1】只收扩展帧public UInt32 Start;    //帧起始idpublic UInt32 End;      //帧结束id
