【正文】 here it is now endangered ancient device, it makes people who saw her could not fet the display effect, exclamation, 40 years ago has even started creating endowed with such artistic breath, in order to make this ancient and very artistic devices send fail waste heat, POV clock according to glow tube design, this design used 80c52 chip as the core, the glow, according to the use of DS1302 realtime calendar clock chip to plete the basic function of the clock. This method has the advantage of reliable performance, good realtime, time, simple operation, easy programming. Understand the internal structure of singlechip microputer and program piling and simulation burning, etc, to better grasp the program structure and the modularized program design, for the development and application of singlechip microputer in the future to lay the foundation. KEY WORDS： Glow Tube, MCU, Programming, Design, Simulation， Electronic clock 2 目錄 前 言 .......................................................................... 0 1 輝光管簡(jiǎn)介 ................................................................... 1 2 單片機(jī)及主要芯片相關(guān)知識(shí) ...................................................... 2 .............................................................. 2 .......................................................... 2 .......................................................... 3 AT89C52單片機(jī)的介紹 ................................................. 4 主要芯片簡(jiǎn) 潔 ............................................................. 7 2． 三極管 2N5551功能及引腳圖 ............................................ 8 十進(jìn)制解碼器 HD74LS145芯片功能及引腳 .................................. 8 時(shí)鐘芯片 DS1302功能及引腳 ............................................ 10 PROTEUS 軟件簡(jiǎn)介 .......................................................... 10 2． 3． 1 keilc51 軟件 ....................................................... 12 3 硬件電路設(shè)計(jì) ................................................................ 13 ................................................... 13 ......................................................... 13 ............................................................. 14 ................................................................. 18 4 結(jié)論 ........................................................................ 22 參考文獻(xiàn) ...................................................................... 23 附件 .......................................................................... 24 0 前 言 隨著電 子技術(shù)的不斷發(fā)展，輝光管慢慢退去了昔日的光輝，但是輝光管是 電子技術(shù)發(fā)展歷史的見證之一，相信有很多朋友對(duì)其了解甚少甚至從未親眼所見。該方法既能準(zhǔn)確驗(yàn)證所設(shè)計(jì)的系統(tǒng)是否滿足技術(shù)要求 ,又能提高系統(tǒng)設(shè)計(jì)的效率和質(zhì)量 ,降低開發(fā)成本 ,具有推廣價(jià)值。古老的器件在經(jīng)過設(shè)計(jì)師精心設(shè)計(jì)后賦予了非常強(qiáng)烈的現(xiàn)代感 ，是古典科技與現(xiàn)代藝術(shù)的完美結(jié)合，從而成為經(jīng)典中的珍品。 圖 1 輝光管外觀圖 輝光數(shù)碼管需在強(qiáng)電場(chǎng)作用下才能啟輝，因此，在譯碼器與輝光數(shù)碼管之間必須配 有電子開關(guān)，如圖中的 VT1VT10便是半導(dǎo)體三極管組成的開關(guān)電路。 8位單片機(jī)： 1972年，美國(guó) Intel公司首先推出 8位微處理器 8008，并于 1976年 9月率先推出MCS48系列單片機(jī)。 16位單片機(jī)主要用于工業(yè)控制，智能儀器儀表，便攜式設(shè)備等場(chǎng)合。能靈活，方便地應(yīng)用于各種智能化的控制設(shè)備
