DS1302可调的液晶电子时钟
长沙民政职业技术学院《C51程序设计》课程设计报告书题目： ds1302可调液晶显示时钟班级：自动化0935学号： 0931903352姓名：刘飞成绩：课程设计报告格式一、绪言（一）设计任务（简要说明设计题目的目的、意义、内容等）（二）提出方案及方案论证（这两个部分可分开也可合并，主要是就自己的课程设计题目提出一个或几个解决方案，并就不同的方案加以论证，从中精选出最佳的一个方案）（三）原理说明：根据方案论证的结果，简述设计原理，最好能给出较为明了的框图来说明整个设计思路。
二、系统设计（一）电路设计（二）程序流程图（三）C51程序设计，重要的代码要有注释。
三、仿真验证（一）系统仿真调试步骤及方法，写程序或设计电路时，不可避免的会出现这样或那样的错误，这部分主要简述一下自己在整个设计过程中采用的仿真调试步骤及方法，重点阐述对出现的问题的解决方法；四、总结书写格式：1、一级标题为宋体，三号，加粗；二级标题为宋体，小三，加粗；报告正文内容为宋体，小四；1.5倍行间距；一． 绪言1.在信息显示技术中，人们发现了信息数字化的重要作用和意义。
数字化的信息更加准确，同一性，更易传输和识别。
很多信息可以直接由数字表示，从而数字化信息显示又成为信息显示的又一个重要内容。
又从数字化显示发展到字符显示，它把人类特有的语言文字用于显示，这种显示与数字显示合在一起用途更广用量更大。
在这同时，人们还希望用图形和图像进行显示，且显示的内容为五彩缤纷，并且可以实时活动和具有三维立体效果。
这些在二十世纪尾声时都已经陆续实现。
LCD 的计算机器，半导体发光数码管显示（LED ）的汽车计价器，商场的大屏幕广告。
这零零总总的各类显示正为你做着各种各样的服务，相信在不久的将来显示技术的发展将会为人类做出更大的贡献。
Ds1302时钟芯片现在流行的串行时钟电路很多，如DS1302、 DS1307、PCF8485等。
这些电路的接口简单、价格低廉、使用方便，被广泛地采用。
