单片机C语言 串口传输 结构体

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<stdio.h>#include<stdlib.h>/*--------------------------start file---------------------------------*/typedef struct{int id;char name[10];int score;}student;int struct_array(char* des, student *src){int num;char *temp = (char *)  src ;for(num=0;num<sizeof(student);num++)*(des+num)= temp[num];return num;}void array_struct(student * des ,char * src){char* temp = (char *) des;int num;for(num=0 ;num < sizeof(student);num++)*(temp++)= src[num] ;}void show_student(student * name){printf("id is : %d\n",name->id);printf("name is : %s\n",name->name);printf("score is : %d \n",name->score);}void show_array(char *str ,int len ){printf("len is : %d \n" ,len);while(len--){putchar('|');putchar(*str++);}printf("|\n");}int main(){char name[10] ="laomao";student laomao = { 123 , {"laomao"} , 99 } ; char save[100] ;int len ;student * answer;len = struct_array(save, &laomao) ;show_array(save , len);array_struct(answer , save) ;show_student(answer);show_student(&laomao);return 0;}/*---------------------------end file----------------------------------*/

运行结果：

-------------------------------------------------------

len is : 20
|{| | | |l|a|o|m|a|o| | | | | | |c| | | |
id is : 123
name is : laomao
score is : 99
id is : 123
name is : laomao
score is : 99
