摘要:數碼管是一類顯示屏通過對其不同的管腳輸入相對的電流,會使其發亮,從而顯示出數字能夠顯示時間、日期、溫度等所有可用數字表示的參數。由于它的價格便宜,使用簡單,在電器特別是家電領域應用極為廣泛,空調、熱水器、冰箱等。絕大多數熱水器用的都是數碼管,其他家電也用液晶屏與熒光屏。
然而在信息時代的今天,單片機技術應用越來越廣泛,涉及各行各業,也滲透到人們的日常生活之中,如洗衣機、空調、冰箱等的控制系統,就可以用單片機實現。為了讓人們很直觀的了解相關設備當前的工作狀態,很多時候需要將當前的時間、溫度、工作程序等狀態通過數碼管顯示出來,這就涉及到單片機的數碼管顯示技術。動態顯示是一種最常見的多位顯示方法,應用非常廣泛。
關鍵詞:數碼管,動態顯示
Abstract:The digital tube is a kind of display. It can brighten the lightsthrough the input of the relative current to the different pins, so that thenumber can display all the available parameters expressed by time, date,temperature and so on. Because of its cheap price and simple use, it is widelyused in electrical appliances, especially household appliances, airconditioners, hot water heaters, refrigerators and so on. Most of the waterheaters are used in the digital tube, and the other appliances also use the LCDscreen and the fluorescent screen.
However, in today's informationage, the application of single chip microcomputer technology is more and moreextensive. It involves all walks of life and penetrates into people's dailylife. For example, the control system of washing machines, air conditioners,fridges and so on can be realized by single chip microcomputer. In order tomake people understand the current working state of related devicesintuitively, many times, we need to display the current time, temperature,working procedures and other status through digital tube, which involves thetechnology of digital tube display of single chip microcomputer. Dynamicdisplay is one of the most common multi - digit display methods, which iswidely used.
Keywords: Digital tube, dynamic display
