1、 南通大學(xué)電氣工程學(xué)院 微機(jī)原理課程設(shè)計(jì) 報(bào)告書課 題 名： 點(diǎn)陣屏顯示屏 班 級(jí)：自113 組 長(zhǎng)： 孫帥 1112011079 組 員： 衛(wèi)軍會(huì) 1112011078 王錫霖 1112011080王棟偉1112011076指導(dǎo)教師：陳越 目錄1. 設(shè)計(jì)目的22. 設(shè)計(jì)內(nèi)容23. 設(shè)計(jì)要求24. 設(shè)計(jì)原理及流圖35. 硬件電路圖46. 程序代碼47. 程序級(jí)系統(tǒng)硬件調(diào)試情況108. 設(shè)計(jì)總結(jié)與體會(huì)119. 參考文獻(xiàn)11一、 設(shè)計(jì)目的課程設(shè)計(jì)是培養(yǎng)和鍛煉學(xué)生在學(xué)習(xí)完本門課后綜合應(yīng)用所學(xué)理論知識(shí)，解決實(shí)際工程設(shè)計(jì)和應(yīng)用問題的能力的重要教學(xué)環(huán)節(jié)。它具有動(dòng)手、動(dòng)腦和理論聯(lián)系實(shí)際的特點(diǎn)，是培養(yǎng)在校工科

2、大學(xué)生理論聯(lián)系實(shí)際、敢于動(dòng)手、善于動(dòng)手和獨(dú)立自主解決設(shè)計(jì)實(shí)踐中遇到的各種問題能力的一個(gè)重要教學(xué)環(huán)節(jié)。通過課程設(shè)計(jì)，要求學(xué)生熟悉和掌握微機(jī)系統(tǒng)的軟件、硬件設(shè)計(jì)的方法、設(shè)計(jì)步驟，使學(xué)生得到微機(jī)開發(fā)應(yīng)用方面的初步訓(xùn)練。讓學(xué)生獨(dú)立或集體討論設(shè)計(jì)題目的總體設(shè)計(jì)方案、編程、軟件硬件調(diào)試、編寫設(shè)計(jì)報(bào)告等問題，真正做到理論聯(lián)系實(shí)際，提高動(dòng)手能力和分析問題、解決問題的能力，實(shí)現(xiàn)由學(xué)習(xí)知識(shí)到應(yīng)用知識(shí)的初步過渡。通過本次課程設(shè)計(jì)使學(xué)生熟練掌握微機(jī)系統(tǒng)與接口擴(kuò)展電路的設(shè)計(jì)方法，熟練應(yīng)用8086匯編語言編寫應(yīng)用程序和實(shí)際設(shè)計(jì)中的硬軟件調(diào)試方法和步驟，熟悉微機(jī)系統(tǒng)的硬軟件開發(fā)工具的使用方法。通過課程設(shè)計(jì)實(shí)踐，不僅要培養(yǎng)學(xué)

3、生事實(shí)求是和嚴(yán)肅認(rèn)真的工作態(tài)度，培養(yǎng)學(xué)生的實(shí)際動(dòng)手能力，檢驗(yàn)學(xué)生對(duì)本門課學(xué)習(xí)的情況，更要培養(yǎng)學(xué)生在實(shí)際的工程設(shè)計(jì)中查閱資料，撰寫設(shè)計(jì)報(bào)告表達(dá)設(shè)計(jì)思想和結(jié)果的能力。二、 設(shè)計(jì)內(nèi)容利用點(diǎn)陣屏顯示漢字三、 設(shè)計(jì)要求（1） 通過四個(gè)8*8點(diǎn)陣組成16*16點(diǎn)陣屏（2） 一個(gè)16*16點(diǎn)陣顯示多個(gè)漢字（3） 多個(gè)漢字循環(huán)在點(diǎn)陣屏上顯示 四、 設(shè)計(jì)原理LED陣列的顯示方式是按顯示編碼的順序，一列一列地顯示。每一列的顯示時(shí),由于人類的視覺暫留現(xiàn)象，將感覺到一列LED是在同時(shí)顯示的。若顯示的時(shí)間太短，則亮度不夠，若顯示的時(shí)間太長(zhǎng)，將會(huì)感覺到閃爍。本文采用低電平逐列掃描，高電平輸出顯示信號(hào)。即輪流給列信號(hào)輸出低

4、電平，在任意時(shí)刻只有一列發(fā)光二極管是處于可以被點(diǎn)亮的狀態(tài) ，其它行都處于熄滅狀態(tài)。為了方便調(diào)試本文把4塊8*8組成的16*16的點(diǎn)陣屏的行信號(hào)輸出管腳連接到兩個(gè)74HC574的輸出端，列信號(hào)掃描輸出管腳連接到另外兩個(gè)&￥HC574的輸出端。程序流程圖：開始初始化將行取低電平將列取高電平行掃描列數(shù)據(jù)取數(shù)據(jù)區(qū)數(shù)據(jù)延時(shí)N是否顯示完漢字Y結(jié)束8*8點(diǎn)陣1) 8X8點(diǎn)陣LED工作原理說明8X8點(diǎn)陣LED結(jié)構(gòu)如下圖所示從圖上中可以看出，8X8點(diǎn)陣共需要64個(gè)發(fā)光二極管組成，且每個(gè)發(fā)光二極管是放置在行線和列線的交*點(diǎn)上，當(dāng)對(duì)應(yīng)的某一列置1電平，某一行置0電平，則相應(yīng)的二極管就亮；因此要實(shí)現(xiàn)一根柱形的

5、亮法，如圖49所示，對(duì)應(yīng)的一列為一根豎柱，或者對(duì)應(yīng)的一行為一根橫柱，因此實(shí)現(xiàn)柱的亮的方法如下所述：一根豎柱：對(duì)應(yīng)的列置1，而行則采用掃描的方法來實(shí)現(xiàn)。一根橫柱：對(duì)應(yīng)的行置0，而列則采用掃描的方法來實(shí)現(xiàn)。五、 硬件電路圖 原理圖： 六、 程序代碼XL EQU 9004H; 行低八XH EQU 9006H; 行高八YL EQU 9000H; 列低八YH EQU 9002H; 列高八DATA SEGMENTFont:DB 004H,000H,0E4H,0FFH,0E4H,0FFH,024H,008HDB 064H,009H,0E4H,009H,0A4H,009H,03FH,07FHDB 03FH,0
