系统设计

3.1设计方案

该电路由时钟模块，液晶模块，键盘扫描模块组成。

时钟模块：由时钟模块1307实现，能够正确显示北京时间，以及扩展显示

星期等等。

液晶模块：将时钟模块的信息正确的显示到液晶显示屏上，使用1602的液

晶。

键盘扫描模块：对十六个按键进行逐次扫描，扫描到前八个按键时，蜂鸣器

依次发出1，2，3，4，5，6，7，8的音调声。其余按键，可以跳转到不同的曲

目以及液晶模块显示，保留几个按键做以后的扩展用。

第6章心得体会
这次实验总共经历了两周的时间，从功能需求分析到功能分析，从程序的设计到程序的调试，下载，最后终于完成了这次具有实际使用价值的实验。

在设计中我运用自己平时学到的一些知识，以及自己在课下所查找的进行设计，刚开始遇到很多困难，包括对使用C语言环境语言的不熟悉，后来一起和同学研究，而一些课程设计中的故障，也请同学帮忙参考一下，最终找到了解决问题的答案。
我感觉自己在设计方面提高很大，特别是在设计程序时，逻辑思维能力有所加强，同时对以

前所学的知识有了更深刻的认识，并进一步的得到了巩固和提高，充
分的做到了理论联系实际，也使我认识到理论与实际的差别，通过该
课程设计，
平时学习中的缺陷。对以后的学习也有很大的帮助。
两周的课程设计，我所收获的不仅是学习知识方面，更多的是生

活方面。我了解到，在我们生活中，应该学会与别人共同分享，分享知识，分享问题，这样更有助于我们的交流，有利于我们共同进步，有利于我们对学习养成良好的兴趣。

最后，我要感谢那些带我们课程设计的老师们，感谢你们对我们的耐心，感谢你们对我们的鼓励，让我们有信心继续下去，成功走到

最后。
