我的通信口比较多，有2个can3个串口，所以我想用结构体来写，大家觉得怎么样？

    struct
    {
    unsigned char TYPE;                   //类型
    unsigned char SN;                            
    unsigned char MD;                     //命令
    unsigned char CM;
    unsigned char P1;
    unsigned char P2;
    unsigned char P3;
    unsigned char P4;
    unsigned char P5;
    unsigned char CK1;
    unsigned char CK2;   
    unsigned char Start;
    unsigned char End;
    unsigned char length;                         //一个帧的基本长度
    }REV;

    struct
    {                        
    unsigned char TYPE                          //=ArmComModule.REV.BUFFER[]  类型
    unsigned char SN;                            
    unsigned char MD;
    unsigned char CM;
    unsigned char P1;
    unsigned char P2;
    unsigned char P3;
    unsigned char P4;
    unsigned char P5;
    unsigned char CK1;
    unsigned char CK2;   
    unsigned char Start;
    unsigned char End;
    unsigned char length;                         //一个帧的基本长度
    }SEND;

struct Communicatemodule
{  

    unsigned char RevBuffSize;                    //接收缓冲区大小
    unsigned char SendBuffSize;                   //发送缓冲区大小
    unsigned char *PushData;                      //定义指向char的地址PushData
    unsigned char RevBuf[RevBuffSize];            //串口接受缓冲区
    unsigned char TraBuf[SendBuffSize];           //串口发送缓冲区
    unsigned char RxdCnt;                         //串口接受字节个数计数器
    unsigned char TxdCnt;                         //串口发送字节个数计数器
    unsigned char sendptr                         //发送指针
    unsigned char RevFlag;                        //通讯响应 作为从机的通信处理标识
    unsigned char SendFlag;                       //发送标识
    unsigned char wptr;                           //写指针
    unsigned char rptr;                           //读取指针
    unsigned char overflow;                       //定义溢出
    SEND;                                         //发送结构体
    REV;                                          //接收结构体
    void (*send)(unsigned char l,unsigned int point,unsigned char whichone);  //发送函数
    void (*selfcheck)(void);                      //通信模块自检测  

}Arm,DRIVER,CAN;

 

struct
{
ARM;
DRIVER;
CAN;

}COMM


到时候我要修改比较方便比如，我要把can的数据头都改下，只要COMM.CAN.REV.START= 什么就行了。你们觉得怎么样这样？

正点原子

可以啊。。。
