Abstract:
We have noticed that the time is continuously updated in PC even though the computer is off. To realize this
task, we have interfaced two chips: microcontroller (89C51) and real time clock (DS 12887). The result of
this is to access the data provided by RTC and displayed it on the 7-segment displays and by using these data
realizing timekeeping. Time keeping means by programming we can set alarm before many year. We can
build a programmer that will keep track of our programs. In addition of this we are provided one function
called day-light-saving, by using this feature we can change our settings in winter and summer accordingly.
摘要：
我們知道，時(shí)鐘就算在電腦關(guān)閉狀態(tài)下也是不斷更新的。為了實(shí)現(xiàn)這個(gè)功能，我們要接上兩個(gè)芯片：?jiǎn)纹瑱C(jī)（AT89C51）和實(shí)時(shí)時(shí)鐘芯片（DS12887）。這樣的結(jié)果是：訪問(wèn)RTC提供的數(shù)據(jù)并使用它們，使其顯示在7段數(shù)碼管上，從而實(shí)現(xiàn)計(jì)時(shí)。這種計(jì)時(shí)意味著我們可以通過(guò)程序在前幾年就設(shè)置好報(bào)警。我們可以有一個(gè)程序員，讓其跟蹤我們的程序。此外，我們還提供一種叫做day-light-saving的功能，使用這種功能,我們可以改變?cè)O(shè)置,在冬季和夏季進(jìn)行相應(yīng)的調(diào)整。
