带温度测量LCD显示的红外遥控数字钟

主要功能为：DS1302，DS18B20，液晶1602驱动
万能电视遥控器（000）的解码。
用遥控器控制DS1302的各种功能
DS18B20的精度为0.06摄氏度
DS1302有蜂鸣器定时报警，继电器控制高电家器，蜂鸣器整点报时
接口：蜂鸣器P2.2
继电器 K1：P2.1 K2：P2.0
每秒闪灯 P3.1
红外接收头 P3.2外部中断零T0
按键：KEY1：P3.3（调整时间及切换）P3.4（调蜂鸣器定时） P3.5（调继电器定时）
DS18B20：数据传送DQ P3.7
DS1302 ：CEP2.7 CK=P2.5 IO=P2.6
液晶1602：RS P1.0 RW P1.1 EN P1.2 数据传输接口 P0

注：程序中青色显示部分为可扩展部分
