摘 要
单片机技术发展迅速，由于他的微小、易用、多功能在智能仪器、家用电器、电子通信、工业控制等方面应用广泛。单片机是集CPU ,RAM ,ROM ,定时，计数和多种接口于一体的微控制器，它体积小、成本低、功能强，而51系列单片机是各单片机中最为典型和最有代表性的一种。这次毕业设计通过对它的学习、应用从而达到学习、设计、开发软、硬的能力。
电子万年历主要采用AT89S52单片机作为主控核心，由DS1302时钟芯片提供时钟、LED动态扫描显示屏显示。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 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.
