摘要
随着科技的快速发展,时间的流逝,至从观太阳、摆钟到现在电子钟,人类不断研究,不断创新纪录。美国DALLAS公司推出的具有涓细电流充电能的低功耗实时时钟电路DS1302。它可以对年、月、日、周日、时、分、秒进行计时,还具有闰年补偿等多种功能,而且DS1302的使用寿命长,误差小。对于数字电子万年历采用直观的数字显示,可以同时显示年、月、日、周日、时、分、秒和温度等信息,还具有时间校准等功能。该电路采用AT89S52单片机作为核心,功耗小,能在3V的低压工作,电压可选用3~5V电压供电。
综上所述此万年历具有读取方便、显示直观、功能多样、电路简洁、成本低廉等诸多优点,符合电子仪器仪表的发展趋势,具有广阔的市场前景。
本设计是基于51系列的单片机进行的电子万年历设计,可以显示年月日时分秒及周信息,具有可调整日期和时间功能。在设计的同时对单片机的理论基础和外围扩展知识进行了比较全面准备。在硬件与软件设计时,没有良好的基础知识和实践经验会受到很大限制,每项功能实现时需要那种硬件,程序该如何编写,算法如何实现等,没有一定的基础就不可能很好的实现。
具体实现功能:
显示年月日时分秒及星期信息
具有可调整日期和时间功能
与即时时间同步
Abstract
With the society, science and technology, mankind learned that time, from the view of the sun, to the present electronic clock pendulum clock, continuous research and innovation. Observation time in
the same time, be able to understand other human beings is closely related to information, such as temperature, week, date and so on, the birth of the electronic calendar, and it set the time, date, week and temperature-in-one, with easy to read, intuitive display functional diversity, and many other advantages of simple circuit with the electronic instrumentation of the development trend of the.
market prospects are broad
The main use of the electronic calendar AT89S52 single-chip microcomputer as the main core, provided by the DS1302 clock chip clock, LCD display shows the number. AT89S52 single-chip microcomputer is introduced by Atmel Corporation, a small power consumption, voltage can be selected 4 ~ 6V power supply voltage; DS1302 clock chip is introduced DALLAS fine with trickle charge function of current low-power real-time clock chip, which can of the year, month, day, week, hour, minute, second for time, also has multiple functions, such as a leap year compensation, and long life of the DS13
