首先对寄存器地址进行宏定义

MAX44009_Reg.h

#ifndef _MAX44009_REG_H
#define _MAX44009_REG_H

#define 	MAX44009_Interupt_Status 			0x00
#define		MAX44009_Interrupt_Enable 			0x01
#define		MAX44009_Configuration				0x02
#define		MAX44009_Lux_High_Byte				0x03
#define		MAX44009_Lux_Low_Byte				0x04
#define		MAX44009_Upper_Threshold_High_Byte	0x05
#define		MAX44009_Lower_Threshold_High_Byte	0x06
#define		MAX44009_Threshold_Timer			0x07


#endif

然后写MAX44009.c文件

#include "stm32f10x.h"                  // Device header
#include"MAX44009_Reg.h"
#include<math.h>
#define MAX44009_ADDRESS		0x94

void MAX44009_WaitEvent(I2C_TypeDef*I2Cx , uint32_t I2C_EVENT) //等待EV时间结束
{
	uint32_t Timeout;
	Timeout = 100000;
	while (I2C_CheckEvent(I2Cx,I2C_EVENT) != SUCCESS)
	{
		Timeout --;
		if (Timeout =&
