我不知道我的代码会发生什么，但看起来它有扫描函数的某些功能。 每当我在功能上按下rx时，功能上的模式1会像我已经输入的那样已经输入了很长时间。 我不知道如何分辨细节，只要问我是否有一些你想知道的东西..
这是我的代码

答案 0 :(得分：0)
我认为问题是你的角色数组大小是12，你试图存储一个长度为12的字符串。但是请记住，你只能存储11个字符+＆＃39; \ 0＆＃39;。
因此，将所有字符数组大小更改为13.还要确保scanf只需12个字符。
char bc[13] = ""; //Better to initialize the array. Anyway you are doing scanf() and get the proper value. I don't see any issue.
[...]
scanf("%12s", bc); //Accept only 12 characters + '\0'.
[...]
第二个问题是strtoul（）。它返回unsigned long int值并将其存储在unsigned char中，这是错误的。所以改变
unsigned char resultxo1,resultxo2,resultxo3,resultxo4,resultxo5,resultxo6;
到
unsigned long int resultxo1,resultxo2,resultxo3,resultxo4,resultxo5,resultxo6;
第3个问题是memcpy（）。要使用strtoul（），第一个参数必须是一个字符串。所以改变
memcpy(partby, stdby + b, 2); b += 2;
resultby1 = strtoul(partby, NULL, 16);
memcpy(partby, stdby + b, 2); b += 2;
resultby2 = strtoul(partby, NULL, 16);
memcpy(partby, stdby + b, 2); b += 2;
resultby3 = strtoul(partby, NULL, 16);
memcpy(partby, stdby + b, 2); b += 2;
resultby4 = strtoul(partby, NULL, 16);
memcpy(partby, stdby + b, 2); b += 2;
resultby5 = strtoul(partby, NULL, 16);
memcpy(partby, stdby + b, 2); b += 2;
resultby6 = strtoul(partby, NULL, 16);
b = 0;
到
partby[2] = '\0'; //You are copying to partby[0] and partby[1] only.
memcpy(partby, stdby + b, 2); b += 2;
resultby1 = strtoul(partby, NULL, 16);
memcpy(partby, stdby + b, 2); b += 2;
resultby2 = strtoul(partby, NULL, 16);
memcpy(partby, stdby + b, 2); b += 2;
resultby3 = strtoul(partby, NULL, 16);
memcpy(partby, stdby + b, 2); b += 2;
resultby4 = strtoul(partby, NULL, 16);
memcpy(partby, stdby + b, 2); b += 2;
resultby5 = strtoul(partby, NULL, 16);
memcpy(partby, stdby + b, 2); b += 2;
resultby6 = strtoul(partby, NULL, 16);
b = 0;
您需要对所有数组和结果变量进行所有这些更改。
