C51单片机控制的数字钟

自从单片机技术实现迅猛发展之后,很多电子产品纷纷开始进入大家的视线,这不仅在发展社会生产力的过程中起到了很大的促进作用,而且还有效改善了社会信息化水平,并让大家对各类电子产品的需求也在慢慢上升。尤其是在节奏紧凑的现代环境下,大家都非常在意时间观念,真正让“时间就是金钱”的这种思想得到了深入贯彻。特别是在处理一些重大事项的时候,一秒钟都不能耽搁,因此相对于传统时钟而言,这种将数码管当做显示器的电子钟显然更容易获得大众的青睐。因为它既方便大家快速对时间进行读取,同时又可以精确到秒。所以作者在下文中基本上就是以AT89C51单片机为主来展开相应的设计,并针对其各项功能进行认真的分析,涉及到硬件中的各个结构,充分利用时钟芯片DS1302来将具体的时间以及日期给详细记录下来。除此之外,这种数字时钟还采取了LED数码管,这样可以将时间非常清楚的展现在显示屏上面,用起来极为方便,无需人为动手调节,现如今已经在各个行业都得到了普及。因为它不用耗费太多的成本,还存在比较大的市场发展空间,所以也就获得了消费者的高度认可。

Since the rapid development of single-chip microcomputer technology,many electronic products have begun to enter everyone's line of sight,which has not only played a great role in promoting the development of social productive forces,but also effectively improved the level of social informationization,thus keeping everyone's demand for all kinds of electronic products slowly rising.Especially in the compact modern environment,everyone is very concerned about the concept of time,so that the idea that"time is money"has been deeply implemented.Especially when dealing with some important matters,it can not be delayed for a second.So compared with the traditional clock,this kind of electronic clock which uses the digital tube as a display is obviously easier to be favored by the public.Because it not only makes it convenient for everyone to read the time quickly,but also can be accurate to seconds at the same time.Thus,the author basically launches the corresponding design based on the AT89C51 single-chip microcomputer in the following,and carries on the careful analysis to its various functions,involves each structure in the hardware,makes full use of the clock chip DS1302 to record the specific time and date in detail.In addition,this digital clock also adopts LED digital tube,which can show the time very clearly on the display screen.It is very convenient to use and does not need to be manually adjusted.Now it has been widely used in various industries.Because it does not cost too much cost,there is still a relatively large space for market development,so it has been highly recognized by consumers.
