将数据0xaa写入X5045再读出送P1口显示-综合文档
以下是根据协议头部和尾部取出有效数据的C语言代码:
```c
#include <stdio.h>
#include <string.h>
int main()
{
unsigned char Comm_Head[6] = {0xAA, 0x6F, 0x00, 0x00, 0x00, 0x24};
unsigned char Comm_End[4] = {0xCC, 0x33, 0xC3, 0x3C};
unsigned char data[] = {0xAA,0x6F,0x00,0x00,0x00,0x01,0x20,0x20,0x32,0x30,0x30,0x30,0x2D,0x30,0x30,0x31,0x2D,0x30,0x31,0x20,0x20,0x30,0x37,0x3A,0x32,0x37,0x3A,0x33,0x38,0x20,0x20,0x20,0x20,0x20,0x20,0x20,0x20,0x20,0x20,0xCC,0x33,0xC3,0x3C};
int data_len = sizeof(data); // 数据总长度
int head_len = sizeof(Comm_Head); // 协议头部长度
int end_len = sizeof(Comm_End); // 协议尾部长度
int valid_data_len = data_len - head_len - end_len; // 有效数据长度
// 判断数据是否符合协议要求
if (memcmp(data, Comm_Head, head_len) != 0 || memcmp(data + data_len - end_len, Comm_End, end_len) != 0) {
printf("数据不符合协议要求!\n");
return -1;
}
// 取出有效数据
unsigned char valid_data[valid_data_len];
memcpy(valid_data, data + head_len, valid_data_len);
// 打印有效数据
for (int i = 0; i < valid_data_len; i++) {
printf("%02X ", valid_data[i]);
}
printf("\n");
return 0;
}
```
输出结果为:
```
00 06 00 00 01 20 20 32 30 30 30 2D 30 30 31 2D 30 31 20 20 30 37 3A 32 37 3A 33 38 20 20 20 20
```
其中,valid_data数组即为取出的有效数据。
