c - 如何将结构体中的字符值写入串行接口(interface)并转换为整数值？

Question

struct MemoryTag1;

typedef struct MemoryTag1{
    char a[8]= {'+','0','2','6','.','5','EA','\r'}; // setpoint temperature value
    char b[8]= {'-','0','2','4','.','5','EB','\r'};
    char c[6]= {'+','0','2','0','EC','\r'};
    }Memory1;

//这是一个消息结构，我想通过串行接口(interface)(RS232)传输该消息结构，然后将其转换为整数值。请在这方面指导我。

你的语法有点不对劲 - 试试这个:

// declare Memory1 struct type to hold data

typedef struct MemoryTag1 {
    char a[9]; // setpoint temperature value
    char b[9];
    char c[7];
} Memory1;

// allocate and initialise a Memory1 struct

Memory1 m = { {'+','0','2','6','.','5','E','A','\r'},
              {'-','0','2','4','.','5','E','B','\r'},
              {'+','0','2','0','E','C','\r'} };
