1、#include"OPT3001IIC.H"#include"Delay.h"#include"OPT3001.h"#include"SHT21.H"#include"Uart.h"ucharmsb=0,lsb=0;short_data;ucharaa=0;//OPT3001寄存器写函数//registerName；寄存器地址//value:需要往寄存器里面写的数据//ADD引脚链接到GNDvoidOpt3001WriteRegister(ucharregisterName,uintvalue){OPT3001IIC_Start();//起

2、始信号OPT3001IIC_Send_Byte(0x88);//发送设备地址+写信号aa=OPT3001IIC_Wait_Ack();OPT3001IIC_Send_Byte(registerName);//发送存储单元地址aa=OPT3001IIC_Wait_Ack();OPT3001IIC_Send_Byte((uchar)(value>>8));aa=OPT3001IIC_Wait_Ack();OPT3001IIC_Send_Byte((uchar)(value&0x00FF));aa=OPT3001IIC_Wait_Ack();OP

3、T3001IIC_Stop();//停止信号}//*********************************************************//读出BMP085内部数据,连续两个//*********************************************************shortOPT3001Multiple_read(ucharST_Address){OPT3001IIC_Start();//起始信号OPT3001IIC_Send_Byte(0x88);//发送设备地址+写信号aa=OPT

5、T3001IIC_Stop();//停止信号Delayms(5);_data=msb<<8;_data

6、=lsb;return_data;}//获取OPT3001的出厂编号默认值读出来应该是0x5449uintGetOPT3001ManufacturerID(){uintIDNum=0;IDNum=OPT3001Multiple_read(MANUFACTURER_ID);//读取returnIDNum;}//获取OPT3001的设备ID初始值为0x3001uintGetOPT3001DeviceID(){uintIDNum=0;IDNum

7、=OPT3001Multiple_read(DEVICE_ID);//读取returnIDNum;}//OPT3001初始化函数//返回值：0为初始化成功//1为初始化失败ucharOPT3001Init(){uintManufacturerIDNum=0;uintDeviceIDNum=0;OPT3001IIC_Init();//OPT3001端口初始化OPT3001Config();//配置OPT3001并且唤醒OPT3001Delayms(5);ManufacturerIDNum=GetOPT3001ManufacturerID();

8、DELAYUS(100);DeviceIDNum=GetOPT3001DeviceID();if(ManufacturerIDNum==0x5449&&DeviceIDNum==0x3001)//如果读出来的ID都正确表示初始化成功{return0;}else//否则初始化不成功{return1;}}//OPT3001寄存器配置//12-15位RN[0,3]:0x1100,设置为Full-ScaleMode//9-10：M[0,1]:0x10,设置OPT3001为连续转换模式//4bit:Latch=1,其他位初始化为00即可voidOPT

9、3001Config(){Opt3001WriteRegister(0x01,0xc410);}//获取光强度得到的是放大100后的值占4个字节unsignedlongGetLu
