说明: 基于51单片机秒表的程序设计
1.设计目的:
(1)利用单片机定时器中断和定时器计数方式实现秒、分定时。
(2)通过LED显示程序的调整,熟悉8155与8051,8155与LED的接口技术,熟悉LED动态显示的控制过程。
(3)通过键盘程序的调整,熟悉8155与矩阵式键盘的接口技术,熟悉键盘扫描原理。
(4)通过阅读和调试简易秒表整体程序,学会如何编制含LED动态显示、键盘扫描和定时器中断等多种功能的综合程序,初步体会大型程序的编制和调试技巧。
(Based on 51 single-chip programming stopwatch 1. Designed to: (1) the use of single-chip timer interrupt and the timer means counts seconds, minutes from time to time. (2) through the LED display adjust procedures, familiar with the 8155 and 8051,8155 and LED interface technology, familiar with the LED dynamic display of the control process. (3) through the keyboard adjust procedures, familiar with the 8155 with keyboard matrix interface technology, familiar with the keyboard scanning principle. (4) By reading and debugging the whole process simple stopwatch, learn how to prepare with LED dynamic display, the keyboard scanning and a variety of functions such as timers interrupt the General procedure, the initial experience of large-scale procedures for the preparation and debugging skills.)
