基于单片机控制的电子万年历的设计 摘要 单片机应用技术飞速发展，纵观我们现在生活的各个领域，从导弹的导航装置，到飞机上各种仪表的控制，从计算机的网络通讯与数据传输，到工业自动化过程的实时控制和数据处理，以及我们生活中广泛使用的各种智能IC卡等，这些都离不开单片机。esign of electronic calendar based on single chip microcomputer control Abstract Microcomputer application technology rapid development, throughout we now all spheres of life, from missile navigation devices, to the aircraft various kinds of instrument control, from the computer network communication and data transmission, to industrial automation process real-time control and data processing, as well as our life is widely used in all kinds of intelligent IC card, these are inseparable from microcontroller. In this design USES the monolithic AT89C52 as controller to control circuit. The design of hardware and software respectively design explains. Hardware including making machines AT89C52 single, clocking circuit DS1302, display circuit and keypad scanning circuit component, such as DS1302 clock chip including real-time clock/calendar and 31 bytes of static RAM. It passes through a simple serial interface and microprocessor communications. Real-time clock/calendar provides seconds, points, when, day, week, month and year and other information. Software part gives part of the program flowchart design, including the Gregorian calendar procedure, time adjustment procedures and lunar program. The Gregorian calendar program DS1302 register read from each year, week, month, day, when data such as, minutes and seconds. Time to adjust to the correct implementation program adjusting time functions. Lunar program is to rely on the Gregorian calendar date of extrapolate. Computative method is, according to the solar calendar days of the year the current date to calculate the lunar calendar date. Software programming using assembly language, because it is simple and easy to use agile and easy to implement procedures of modular and structured.
