毕业设计题目: 多闹点数字钟的设计学生姓名: 朱旭学号: 1110064094 所在院(系):物理与电信工程学院专业班级: 电子信息科学与技术 1103 班指导教师: 宋卫星完成地点: 博远楼 C1004 教室陕西理工学院毕业设计多闹点数字钟的设计朱旭(陕理工物理与电信工程学院电子信息科学与技术专业 1103 班,陕西汉中 723001 ) 指导教师: 宋卫星[ 摘要] 多闹点数字钟是由单片机作为数字钟的核心控制器,通过它的时钟信号进行实现计时功能,将其时间数据经单片机输出,利用显示器显示出来。本设计是以单片机 STC89C52 为核心元件同时采用 LCD 显示器动态显示“时”、“分”、“秒”、“年”、“月”、“日”的现代计时装置。更重要的是具有闹钟功能,至少可设置两个时间闹点,利用单片机实现的数字时钟具有编程灵活,便于功能的扩充等优点。[ 关键词] 多闹点、 STC89C52 、 LCD Make more the design of the digital clock zhuxu ( Grade11,Class3,Major Electronic Information Science and Technology,Physics Dept.,Shaanxi University of Technology,Hanzhong 723000,Shaanxi ) Tutor: Songweixing Abstract : Make more digital clock is mon, by single chip puter as the core of the digital clock controller, through its function of timing clock signal, the time data by the MCU output, using the monitor display. This design has the functions of digital clock timing, when the school, is based on single chip puter AT89C52 as the core element and USES the dynamic display of the LCD display "when", "points" and "second", "year", "month", "day" modern timing devices. Also has alarm clock function, using the singlechip puter digital clock has a flexible programming, function expansion conveviently. Key words : Make more alarm clock 、 STC89C52 、 LCD 陕西理工学院毕业设计目录引言................................................................................................................................................................ 1 1设计要求及目的.............................................................................................................................. 1 设计要求................................................................................................................................. 1 设计思想................................................................................................................................. 1 总体设计方案...................................................................................................................... 1 2硬件设计.......
