微機原理課程設計點陣屏

1、 南通大學電氣工程學院 微機原理課程設計 報告書課 題 名： 點陣屏顯示屏 班 級：自113 組 長： 孫帥 1112011079 組 員： 衛(wèi)軍會 1112011078 王錫霖 1112011080王棟偉1112011076指導教師：陳越 目錄1. 設計目的22. 設計內容23. 設計要求24. 設計原理及流圖35. 硬件電路圖46. 程序代碼47. 程序級系統(tǒng)硬件調試情況108. 設計總結與體會119. 參考文獻11一、 設計目的課程設計是培養(yǎng)和鍛煉學生在學習完本門課后綜合應用所學理論知識，解決實際工程設計和應用問題的能力的重要教學環(huán)節(jié)。它具有動手、動腦和理論聯系實際的特點，是培養(yǎng)在校工科

2、大學生理論聯系實際、敢于動手、善于動手和獨立自主解決設計實踐中遇到的各種問題能力的一個重要教學環(huán)節(jié)。通過課程設計，要求學生熟悉和掌握微機系統(tǒng)的軟件、硬件設計的方法、設計步驟，使學生得到微機開發(fā)應用方面的初步訓練。讓學生獨立或集體討論設計題目的總體設計方案、編程、軟件硬件調試、編寫設計報告等問題，真正做到理論聯系實際，提高動手能力和分析問題、解決問題的能力，實現由學習知識到應用知識的初步過渡。通過本次課程設計使學生熟練掌握微機系統(tǒng)與接口擴展電路的設計方法，熟練應用8086匯編語言編寫應用程序和實際設計中的硬軟件調試方法和步驟，熟悉微機系統(tǒng)的硬軟件開發(fā)工具的使用方法。通過課程設計實踐，不僅要培養(yǎng)學

3、生事實求是和嚴肅認真的工作態(tài)度，培養(yǎng)學生的實際動手能力，檢驗學生對本門課學習的情況，更要培養(yǎng)學生在實際的工程設計中查閱資料，撰寫設計報告表達設計思想和結果的能力。二、 設計內容利用點陣屏顯示漢字三、 設計要求（1） 通過四個8*8點陣組成16*16點陣屏（2） 一個16*16點陣顯示多個漢字（3） 多個漢字循環(huán)在點陣屏上顯示 四、 設計原理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,由于人類的視覺暫留現象，將感覺到一列LED是在同時顯示的。若顯示的時間太短，則亮度不夠，若顯示的時間太長，將會感覺到閃爍。本文采用低電平逐列掃描，高電平輸出顯示信號。即輪流給列信號輸出低

4、電平，在任意時刻只有一列發(fā)光二極管是處于可以被點亮的狀態(tài) ，其它行都處于熄滅狀態(tài)。為了方便調試本文把4塊8*8組成的16*16的點陣屏的行信號輸出管腳連接到兩個74HC574的輸出端，列信號掃描輸出管腳連接到另外兩個&￥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據取數據區(qū)數據延時N是否顯示完漢字Y結束8*8點陣1) 8X8點陣LED工作原理說明8X8點陣LED結構如下圖所示從圖上中可以看出，8X8點陣共需要64個發(fā)光二極管組成，且每個發(fā)光二極管是放置在行線和列線的交*點上，當對應的某一列置1電平，某一行置0電平，則相應的二極管就亮；因此要實現一根柱形的

5、亮法，如圖49所示，對應的一列為一根豎柱，或者對應的一行為一根橫柱，因此實現柱的亮的方法如下所述：一根豎柱：對應的列置1，而行則采用掃描的方法來實現。一根橫柱：對應的行置0，而列則采用掃描的方法來實現。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
