摘要
万年历是我国古代记录时间的主要工具,古人依据天文星象的变化制作而成。而随着时代的发展,尤其是近些年电子行业的快速发展,电子万年历已经成为了我们记录时间的主要工具。引用AT89S51型单片机控制电路,设计了一款电子万年历,其中系统主要由单片机控制电路,显示电路,调整电路三个模块组成。介绍了其工作原理,采用C语言编写,最后进行了验证。不仅显示直观,而且读取方便且时间准确可精确到秒,顺应了大趋势,有很高的经济前景。
Perpetual calendar is the main tool that records the time of ancient China ancient according to change of the astronomtcat astrology, anu w^u~ u t- the rapid development of electronic industry, electronic calendar has become our main tool for recording time. Reference type AT89S51 single-chip microcomputer control circuit, this paper designed a electronic perpetual calendar, the system is mainly composed of single chip microcomputer control circuit, display circuit, adjusting circuit of three modules. Its working principle is introduced. Using C language to write, it is verified at last. It ont only display intuitive, but also is easy to read and accurate and can be accurate to seconds, conform to the trend and has a high economic outlook.
