基于 51 单片机的简易跑表设计摘 要跑表是一种常用的测时仪器，在体育竞赛中有着广泛的应用，用于测量较短且较精确的时间。20 世纪末，电子技术获得了飞速的进展，在其推动下，现代电子产品几乎渗透了社会的各个领域，有力地推动了社会生产力的进展和社会信息化程度的提高，同时也使现代电子产品性能进一步提高，产品更新换代的节奏也越来越快。在这高速进展的当今世界，时间对人们来说无疑是极其宝贵的，时间就是金钱。基于 STC89C51 单片机的简易跑表设计系统，以 STC89C51 单片机为控制核心，提供一种简易跑表的设计与制作，使用这种方案制作的跑表，定时准确，通过 LCD12864 显示，按下第 1 按键开始启动计时操作，按下第 2 按键可以将显示总时间及圈数在当前状态时间继续计时，按下第 3 按键结束计时，显示当前总圈数及总时间。随着人们各方面素养的提高，不仅科学领域得到了飞速进展，运动员们都朝着“更快，更高，更强”的目标努力，特别是一些短跑竞赛，要求计时器要足够精确。设计的跑表功能完善且可靠性高稳定性强，这在各项竞赛中具有实际应用。 关键词：单片机；跑表；体育竞赛；LCD12864；按键AbstractStopwatch is a commonly used measuring instruments, has been widely used in sports competitions, is used to measure time is shorter and more precise. The end of the 20th century, obtained the rapid development of electronic technology, under the push, the modern electronic products almost permeated all fields of society, vigorously promoted the development of social productivity and the enhancement of social information degree, but also makes the modern electronic products performance further improve, product update rhythm also more and more quickly. In the rapid development of today's world, time is very valuable for people, time is money.Simple stopwatch design system based on STC89C51 microcontroller to STC89C51 microcontroller as the control core, the design and manufacture of provides a simple stopwatch, use this plan stopwatch, time accurate, through LCD12864 display, press 1 button t...
