2、示。AT89S52 单片机功耗小、电压可选用 2.0 6V 电压供电; DS1302 时钟芯片是美国 DALLAS 公司推出的具有涓细电流充电功能 的低功耗实时时钟芯片,它可以对年、月、日、星期、时、分、秒进行计时;数 字显示是采用的 LED 液晶显示屏来显示,可以同时显示年、月、日、星期、时、 分、秒和温度等信息。 关键词 万年历;AT89S52 单片机;1602 液晶显示屏;DS1302 时钟芯片. Based on SCM calendar design ABSTRACT Single chip microcomputer development is rapid, because of
3、 his tiny, is easy to use,and multi-function in intelligent instrument, home appliances, electronic communication, industry control, wide application. SCM is set for the CPU, RAM, ROM, time, count and a variety of interface in one of the micro controller. Its small size, low cost, the function is st
4、rong, and 51 series microcontroller is the most typical of single chip microcomputer and the most representative of a kind. The graduation design through to its study, application, so as to study, design, and develop the ability of soft and hard. The electronic calendar mainly USES the AT89S52 SCM as the master its core, and the DS1302 clock chip provide clock, LED dynamic scanning display shows. AT89S52 SCM power consumption is small, voltage can choose 2.0 6 V voltage power supply; DS1
