嵌入式课程（设计文档） 题目：数字电子时钟设计 学 院 专 业 学 号 年 级 姓 名 2011年 12月 14 日数字电子时钟设计 一 实现功能1 基本的数字时钟计时功能2 时间设定功能3 闹钟功能二 设计思路数字时钟在lcd上显示，分为三个部分：时钟，分钟和秒钟，为照顾整体美观性，时钟和分钟为统一大字体，在lcd上用矩形拼凑而成，秒钟为小字体，在lcd上用线画出。秒钟满60自动分钟加一，秒钟重计。分钟满60后时钟自动加一，分钟重计。时钟满二十四后自动清零。在初始时候可以从键盘中输入时钟的时和分进行时间的设定，数字时钟在lcd上显示此时间并以此为基础进行计时。此时钟还有设定闹钟功能，按下开关键sw2由超级终端开始提示输入闹钟时间并亮起led4，由键盘输入设定时间后当时间到达此设定时间则响起闹钟铃声，关闭sw2，则闹钟停止。三 硬件支持 实验设计由MX1下的lcd显示屏，led灯，键盘，开关，音频播放器以及RS232串口通信支持。四
