c51语言自定义头文件,自定义c51头文件missing before unsigned

自定义c51头文件missing before unsigned

自定义了一个头文件 weikong.h

#ifndef _lcd1602_H_

#define _lcd1602_H_

#include

#include "REG51.h"

#include "stdio.h"

#include "intrins.h"

#define uchar unsigned char

extern unsigned int  ReadAD0809(uchar i)  ;

endif

还有一个weikong.c文件

#include

#include

#include

#include "weikong.h"

#define  IN0 XBYTE[0X7FF0]

#define uchar unsigned char

uchar code ledshow[ ] ={0X3F,0X06,0X5B,0X4F,0X66,0X6D,0X7D,0X07,0X7F,0X6F};

unsigned int  ReadAD0809(uchar i)  ;

sbit ad_busy=P1^7;

unsigned int  ReadAD0809(uchar i)

{

uchar xdata *ad_adr;

unsigned int  x;

ad_adr=&IN0+i;

*ad_adr=0;//启动A/D

while(ad_busy==0)

{

;

}

x=*ad_adr;   //取转换结果

return x;

}

编译室出现编译文件WEIKONG.C...

ERROR 129 IN LINE 16 OF WEIKONG.C: missing ';' before 'unsigned'

ERROR 316 IN LINE 85: unterminated conditionals

请问为什么？

语法错误：在错误的地方之前缺少标识符，检查一下你的代码
