摘要
以AT89C2051为中心控制单元,采用汇编语言编程,设计一个用6位数码管显示时、分、秒的时钟。该时钟可实现时间显示、时间调整、闹钟设置、整点报时和省电等多种功能,具有制作简单、调整方便、稳定性好、便于扩展等特点。经实践制作、调试,证明设计可靠、方案可行,尤其是在教学中有较大的实用价值,可以为单片机学习者提供很好的练习题材。
Applying single chip microcomputer AT89C2051 as main control unit, using assemble language to program, designing a kind of multi - functional clock with six LEDs displaying hour,minute and second. The clock carrys out displaying clock,setting clock, adjusting alarm,informing integer or clock etc. It＇s easy to design,convenient to set clock and alarm , work ing credibly and stably. Through producing the physical circuit and debug, it proves that the scheme is reliable and the approach is feasible. It＇s offerd an excellent practice stuff for the MCU learners.
