uchar没定义呗，在最前面加
typedef unsigned char uchar;

时钟中断函数，似乎不需要声明的吧？？？

[northcan]

#include "reg52.h" //引用头部文件

#define uchar unsigned char

void delay(void);
uchar keyscan();

// ... ...

[绿野耕夫]

使用uchar之前需要先typedef
typedef unsigned char uchar;

[吻花者]

嘿嘿，不能只抄袭uchar啊，c里面没有，要自己定义啊！！！！
抄袭也有抄袭全面啊？？？

[狂且]

typedef unsigned char uchar;
typedef unsigned int uint;
//或
#define uchar unsigned char
#define uint unsigned int

要养成开始写代码时就要先定义好这个!

[mxiangliang]

uchar

[夫人的泡泡鱼]

最终版本#define uchar unsigned char
