Question

我用keil编译老是有问题warning C318: can't open file 'i2c.h'和error C129: miss‘；’before ’code‘

#include <reg51.h>
#include<i2c.h>
#define power_down 0x00
#define power_on 0x01
#define reset 0x07
#define h_resolution_mod 0x10
#define m_resolution_mod 0x13
#define l_resolution_mod 0x16
#define onetime_h 0x20
#define onetime_m 0x23
#define onetime_l 0x26
#define write_1710 0x46
#define read_1710 0x47
sbit LCD_RS = P3^4 ;
sbit LCD_RW = P3^5 ;
sbit LCD_EN = P3^3 ;
uchar code cdis1[ ] = {" NFU "} ;
uchar code cdis2[ ] = {" illum: Lux "} ;
uchar code cdis3[ ] = {" BH1710 ERR0R "} ;
uchar code cdis4[ ] = {" PLEASE CHECK "} ;
unsigned char data display[5] = {0x00,0x00,0x00,0x00,0x00} ;
unsigned int bh;
unsigned char code mytab[8] = {0x0C,0x12,0x12,0x0C,0x00,0x00,0x00,0x00} ;
#define delayNOP() ; {_nop_() ;_nop_() ;_nop_() ;_nop_() ;} ;

麻烦各位大神！！！分别是第二行和第17行

Answer 1

你没把I2C.H这个头文件和这个文件放在同一个目录下，所以编译器表示没找到。
uchar不是一种数据类型，必须在使用之前先定义#define uchar unsigned char

Answer 2

确定有i2c.h这个文件？
uchar 这个应该是你自定义的类型 你也确定有？

编译器找不到这两个 你再看看吧
屏蔽第二行 uchar改unsigned char 看看有没有报错
