1 数字钟的设计摘要近年来随着计算机在社会领域的渗透和大规模集成电路的发展,设计单片机的应用正在不断地走向深入。由于它具有功能强,体积小,功耗低,价格便宜,工作可靠,使用方便等特点,因此特别适合于与控制有关的系统。它也越来越广泛地应用于自动控制,智能化仪器,仪表,数据采集,军工产品以及家用电器等各个领域。单片机往往是作为一个核心部件来使用,在根据具体硬件结构, 以及针对具体应用对象特点的软件结合,以作完善。本次做的数字钟是以单片机(8031 )为核心,结合相关的元器件(8729 等), 再配以相应的软件,达到制作简易数字钟的目的,其硬件部分难点在于元器件的选择、布局及焊接。关键词单片机 8031 8729 2 The des i gn of di gi t al cl ock Abstract In recent years, puters in the infiltration and the development of large-scale integrated circuits. SCM application is steadily deepening, as it has strong function, small size, low power dissipation, low prices, reliable, easy to use features, it is particularly suited to and control of the system, increasingly widely used in automatic control, intelligent instruments, gauges, data acquisition, military products and household appliances, and other areas, is often microcontroller asa ponent to use, In light of specific hardware architecture, and application-specific software features bine to make perfect. The figures do bell on SCM (8031) at the core, Combined with ponents (8027), and factoring in the corresponding software, Easy to produce digital clock purposes, as part of the ponents isa difficult choice, layout and welding. Keywords : Single Chip puter 8031 8027 3 目录引言.......................................................................................................................... 1 第1章单片机简介.............................................................................................. 2 概述.................................................................................................................... 2 8031 的引脚功能............................................................................................... 2 8031 的内部结构............................................................................................... 4 第2章设计过程..................................................................................................... 7 程序框图.................................................................
