串口传输 结构体 就是 把结构体 转换为 数组 ，然后传输 数组中的 char。
即 struct - - - - - - ->> char [ ] ;
然后 char[ ] - - - -- - - - -->> struct .
给出一下简单实例代码 ：
#include

typedef struct
{
int id;
char name[10];
int score;
}student;
int struct_array(char* des, student *src)

char *temp = (char *) src ;
for(num=0;num
*(des+num)= temp[num];
return num;
