_工_學(xué)院_2010_級(jí)_電氣工程及其自動(dòng)化_專業(yè) 姓名_魯晚霞（2010180137）、劉春蘭（2010180131）、史兆成（2010090437）（密）（封）（線）本科課程設(shè)計(jì)專用封面設(shè)計(jì)題目：基于12864LCD顯示屏的數(shù)字時(shí)鐘 所修課程名稱： 單片機(jī)應(yīng)用技術(shù)課程設(shè)計(jì) 修課程時(shí)間： 2013 年 10 月 21 日至 10 月 27 日完成設(shè)計(jì)日期： 2013 年 10 月 27 日評(píng)閱成績(jī)： 評(píng)閱意見：評(píng)閱教師簽名： 年 月 日目錄一、設(shè)計(jì)要求1二、設(shè)計(jì)步驟22. 鍵盤3二、設(shè)計(jì)程序4 1. 單片機(jī)與外部模塊控制引腳分配4四、調(diào)試過程5五、設(shè)計(jì)結(jié)果及總結(jié)5附件61.程序代碼6一、設(shè)計(jì)要求此次設(shè)計(jì)使用STC89C52單片機(jī)作為主控芯片，配合實(shí)驗(yàn)箱上面其它模塊而進(jìn)行。為實(shí)現(xiàn)課題要求，主要使用的有液晶LCD12864模塊、獨(dú)立鍵盤等。此設(shè)計(jì)要求主要有以下幾點(diǎn)：1. 使用液晶界面。2. 液晶初始界面顯示“北京時(shí)間”、“感謝你：宰老師！”字樣。3. 數(shù)字時(shí)鐘。4. 時(shí)鐘的時(shí)間可由四個(gè)獨(dú)立按鍵控制調(diào)整。 此設(shè)計(jì)的基本現(xiàn)實(shí)構(gòu)思如下圖所示。圖1. 液晶界面構(gòu)想顯示圖二、設(shè)計(jì)步驟1. LCD12864液晶顯示屏 帶中文字庫的12864是一種具有4位/8位并行、2線或3線串行多種接口方式，內(nèi)部含有國(guó)標(biāo)一級(jí)、二級(jí)簡(jiǎn)體中文字庫的點(diǎn)陣圖形液晶顯示模塊；其顯示分辨率為12864, 內(nèi)置8192個(gè)16*16點(diǎn)漢字，和128個(gè)16*8點(diǎn)ASCII字符集.利用該模塊靈活的接口方式和簡(jiǎn)單、方便的操作指令，可構(gòu)成全中文人機(jī)交互圖形界面?？梢燥@示84行1616點(diǎn)陣的漢字. 也可完成圖形顯示.低電壓低功耗是其又一顯著特點(diǎn)。由該模塊構(gòu)成的液晶顯示方案與同類型的圖形點(diǎn)陣液晶顯示模塊相比，不論硬件電路結(jié)構(gòu)或顯示程序都要簡(jiǎn)潔得多，且該模塊的價(jià)格也略低于相同點(diǎn)陣的圖形液晶模塊。圖2 12864接口與實(shí)驗(yàn)箱上的接口圖八根數(shù)據(jù)線與單片機(jī)P0相連，控制端RS、RW、EN分別接于單片機(jī)的P2.3、P2.4、P2.5。2. 鍵盤 此設(shè)計(jì)需要使用到四個(gè)獨(dú)立按鍵，用來調(diào)整數(shù)字時(shí)鐘的顯示。圖3 實(shí)驗(yàn)箱獨(dú)立鍵盤接線示意圖二、設(shè)計(jì)程序1. 單片機(jī)與外部模塊控制引腳分配圖4 單片機(jī)引腳分配示意圖按鍵控制及說明1. K1：P3.2 功能：按一下，時(shí)鐘進(jìn)入待調(diào)整狀態(tài)，時(shí)位閃爍；再次按一下回復(fù)。2. K2：P1.0 功能：按一下，閃爍位在時(shí)分秒間循環(huán)移動(dòng)一位。3. K3：P1.1 功能：按一下，閃爍位數(shù)字加一。4. K4：P1.2 功能：按一下，閃爍位數(shù)字減一。三、調(diào)試過程1.將寫好的程序燒錄進(jìn)單片機(jī)。2.將設(shè)計(jì)分配好的單片機(jī)引腳與對(duì)應(yīng)的模塊用線連接起來。3.打開實(shí)驗(yàn)箱的電源。4.待實(shí)驗(yàn)箱通電后，觀察實(shí)驗(yàn)現(xiàn)象。5.測(cè)試各功能按鈕是否正常工作。四、設(shè)計(jì)結(jié)果及總結(jié)一個(gè)星期的單片機(jī)課程設(shè)計(jì)很快就結(jié)束了，在這一周當(dāng)中，雖然開始有點(diǎn)困難，但是經(jīng)過努力學(xué)習(xí)，合理地進(jìn)行設(shè)計(jì)安排，我終于順利地完成了本次單片機(jī)課程設(shè)計(jì)，同時(shí)也學(xué)到了很多東西。 在本次課程設(shè)計(jì)中，通過動(dòng)手實(shí)踐操作，進(jìn)一步學(xué)習(xí)和掌握了單片機(jī)原理的有關(guān)知識(shí)，特別是程序的編程方面，加深了對(duì)單片機(jī)原理及應(yīng)用技術(shù)的認(rèn)識(shí)，進(jìn)一步鞏固了對(duì)單片機(jī)知識(shí)的理解，掌握簡(jiǎn)單單片機(jī)應(yīng)用系統(tǒng)的設(shè)計(jì)、制作的方法。在設(shè)計(jì)時(shí)根據(jù)課題要求，復(fù)習(xí)相關(guān)的知識(shí)，查詢相關(guān)的資料。這次的單片機(jī)課程設(shè)計(jì)重點(diǎn)是通過實(shí)踐操作和理論相結(jié)合，提高動(dòng)手實(shí)踐能力，提高科學(xué)的思維能力，更在一周的時(shí)間了解了更多的有關(guān)單片機(jī)的知識(shí)，使知識(shí)更加豐富，使自己更加充實(shí)。要做好一個(gè)課程設(shè)計(jì)，就必須做到：在設(shè)計(jì)程序之前，對(duì)所用單片機(jī)的內(nèi)部結(jié)構(gòu)有一個(gè)系統(tǒng)的了解，知道該單片機(jī)內(nèi)有哪些資源；要有一個(gè)清晰的思路；在設(shè)計(jì)程序時(shí)，不能妄想一次就將整個(gè)程序設(shè)計(jì)好，反復(fù)修改、不斷改進(jìn)是程序設(shè)計(jì)的必經(jīng)之路；在設(shè)計(jì)的過程中發(fā)現(xiàn)了自己的不足之處，對(duì)以前所學(xué)過的知識(shí)理解得不夠深刻，掌握得不夠牢固。通過查閱大量有關(guān)資料，使自己學(xué)到了不少知識(shí)，也經(jīng)歷了不少艱辛，收獲巨大。但通過學(xué)習(xí)這一次實(shí)踐,增強(qiáng)了我的動(dòng)手能力,提高和鞏固了單片機(jī)方面的知識(shí),特別是軟件方面，并讓我認(rèn)識(shí)到把理論應(yīng)用到實(shí)踐中去是多么重要。當(dāng)然，這次課程設(shè)計(jì)能夠順利完成，離不開組員間默契配合以及老師的悉心指導(dǎo)。附件1.程序代碼/*-
