LCD1602.h(8): error C129: missing ';' before 'LCD1602_RS'

请问这个错误该怎么办？改了很久都不对

#ifndef __LCD1602_H__
#define __LCD1602_H__
#define LCD1602_PORT P0
//#include <reg52.h>
#include <STC89C5xRC.H>


Sbit LCD1602_RS = P2^6;
Sbit LCD1602_RW = P2^5;
Sbit LCD1602_EN = P2^7;

//????????
extern void LCD1602_delay_ms(unsigned int n);
extern void LCD1602_write_com(unsigned char com);
extern void LCD1602_printc(unsigned char dat);
extern void LCD1602_prints(unsigned char *s);
extern void LCD1602_Init();
extern void LCD1602_set_position( bit hang, unsigned char x);           //LCD?????x?
extern void LcdPrintNum(unsigned int num);
#endif

错误在【LCD1602.h】中找。

1. #ifndef __LCD1602_H__
   
2. #define __LCD1602_H__
   
3. #define LCD1602_PORT P0
   
4. //#include <reg52.h>
   
5. #include <STC89C5xRC.H>
   
6. 
   
7. 
   
8. sbit LCD1602_RS = P2^6;  //Sbit LCD1602_RS = P2^6; Sbit 的S是小写 <-----------------
   
9. sbit LCD1602_RW = P2^5;  //Sbit LCD1602_RW = P2^5;
   
10. sbit LCD1602_EN = P2^7;  //Sbit LCD1602_EN = P2^7;
    
11. 
    
12. //????????
    
13. extern void LCD1602_delay_ms(unsigned int n);
    
14. extern void LCD1602_write_com(unsigned char com);
    
15. extern void LCD1602_printc(unsigned char dat);
    
16. extern void LCD1602_prints(unsigned char *s);
    
17. extern void LCD1602_Init();
    
18. extern void LCD1602_set_position( bit hang, unsigned char x);           //LCD?????x?
    
19. extern void LcdPrintNum(unsigned int num);
    
20. #endif

你把小写sbit写成大写Sbit了，在keil编辑器中对关键字的字体和颜色做一下设置，比如设置成蓝色或红色，斜体字等，一眼就可以看出关键字是否写正确了

具体不好说，一种是问题在其它C或h中，另一种是把#include <STC89C5xRC.H>放在文件最前，不要在#ifndef 及#define内试试
