摘 要
單片機技術發(fā)展迅速，由于他的微小、易用、多功能在智能儀器、家用電器、電子通信、工業(yè)控制等方面應用廣泛。單片機是集CPU ,RAM ,ROM ,定時，計數(shù)和多種接口于一體的微控制器，它體積小、成本低、功能強，而51系列單片機是各單片機中最為典型和最有代表性的一種。這次畢業(yè)設計通過對它的學習、應用從而達到學習、設計、開發(fā)軟、硬的能力。
電子萬年歷主要采用AT89S52單片機作為主控核心，由DS1302時鐘芯片提供時鐘、LED動態(tài)掃描顯示屏顯示。AT89S52單片機功耗小、電壓可選用2.0～6V電壓供電；DS1302時鐘芯片是美國DALLAS公司推出的具有涓細電流充電功能的低功耗實時時鐘芯片，它可以對年、月、日、星期、時、分、秒進行計時；數(shù)字顯示是采用的LED液晶顯示屏來顯示，可以同時顯示年、月、日、星期、時、分、秒和溫度等信息。
關鍵詞 萬年歷；AT89S52單片機；1602液晶顯示屏；DS1302時鐘芯片.
Based on SCM calendar design
ABSTRACT
Single chip microcomputer development is rapid, because of 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 strong, 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; DS1302 clock chip is the United States out Juan DALLAS has fine current charge function of low power consumption real time clock chip, it can be to year, month, day, week, when, minutes and seconds for timing; Digital display is USES LED LCD screen to display, can also shows that year, month, day, week, when, minutes and seconds and temperature and other information.
KEY WORDS Calendar;AT89S52 SCM; 1602 LCD; DS1302 clock chip.
