有報錯圖，但是網(wǎng)上的解決方法我都有點看不懂，希望大神們教教小子。謝謝謝謝，講得通俗一點

你把聲明#include<at24c02.h>換成#include "at2402.h"試試

你把聲明#include換成#include "at2402.h"試試

還是不行，它就變成這個了：智能鎖.c(12): error C309: bad or missing filename

你的At24c02 是不是main.c不在一個文件夾啊

ID:277948 · 發(fā)表于 2020-6-20 16:31

option-c/c++ -include path 里面添加試試

你為什么有兩個聲明51.h，你在定義AT2402.h中是怎么定義的，給你看一下我在定義i2c.h里面寫的內(nèi)容
#ifndef __I2C_H_
#define __I2C_H_

#include<reg51.h>

//---重定義關鍵詞---//
#ifndef uchar
#define uchar unsigned char
#endif

#ifndef uint
#define uint unsigned int
#endif

//--定義使用的IO口--//
sbit I2C_SCL = P2^1;
sbit I2C_SDA = P2^0;

//--聲明全局變量--//
void I2C_Delay10us();
void I2C_Start();
void I2C_Stop();
uchar I2C_SendByte(uchar dat, uchar ack);
uchar I2C_ReadByte();

#endif
