顯示器引腳排列如圖2.2.3（b）所示。當(dāng)采用單片機(jī)進(jìn)行控制時(shí)，連接16*16點(diǎn)陣LED顯示器需要接入四片74LS273時(shí)，將16*16點(diǎn)陣LED顯示器分成上下兩部分，上半部分8行16列和下半部分8行16列。1#、2#鎖存器分別控制上八行和下八行，3#、4#鎖存器分別控制左八列和右八列。每一列由兩個(gè)字節(jié)組成，數(shù)據(jù)分成兩次送入掃描一列，顯示一個(gè)字需要掃描16次?！皻g迎光臨”顯示如圖2.2.4，可以按照從左到右，先下后上的順序以此寫(xiě)出“歡迎光臨武漢理工大學(xué)”等字的編碼。“歡迎”顯示字樣圖2.2.4“光臨”顯示字樣圖2.2.5整體電路圖第三章：系統(tǒng)軟件設(shè)計(jì)“歡迎光臨武漢理工大學(xué)”10個(gè)字的編碼表如下：TAB1:DB00H,00H,10H,00H,34H,08H,44H,04H；“歡”字編碼數(shù)據(jù)DB04H,03H,7CH,04H,06H,28H,38H,10HDB0FH,0CH,89H,03H,0F8H,03H,08H,0CHDB28H,18H,1CH,30H,08H,20H,00H,00HTAB2:DB00H,00H,40H,10H,40H,30H,06EH,1FH；“迎”字編碼數(shù)據(jù)DB06CH,18H,00H,10H,00H,24H,0FEH,23HDB02H,21H,82H,20H,0FFH,3FH,02H,21HDB02H,23H,0FFH,21H,02H,20H,00H,00HTAB3:DB00H,00H,40H,00H,44H,20H,48H,20H；“光”字編碼數(shù)據(jù)DB50H,10H,0E0H,0FH,40H,00H,0FFH,1FHDB60H,20H,50H,20H,48H,20H,46H,20HDB60H,20H,40H,10H,00H,00H,00H,00HTAB4:DB0F0H,03H,00H,40H,00H,20H,0FFH,1FH；“臨”字編碼數(shù)據(jù)DB00H,00H,00H,00H,40H,3FH,31H,21HDB1FH,21H,14H,21H,24H,3FH,64H,21HDB44H,21H,46H,21H,04H,3FH,00H,00HTAB5:DB10H,00H,10H,08H,10H,18H,90H,1FH;“武”字點(diǎn)陣數(shù)據(jù)DB14H,08H,0F4H,07H,94H,04H,94H,04HDB14H,04H,10H,00H,0FEH,00H,10H,03HDB12H,0CH,14H,10H,10H,20H,00H,30HTAB6:DB00H,00H,00H,70H,22H,78H,44H,0C4H;“漢”字點(diǎn)陣數(shù)據(jù)DB0CCH,06H,00H,40H,04H,20H,34H,10HDB0C4H,08H,04H,05H,04H,02H,04H,05HDB0C4H,08H,3EH,10H,04H,20H,00H,30HTAB7:DB08H,21H,08H,61H,0F8H,1FH,08H,09H;“理”字點(diǎn)陣數(shù)據(jù)DB08H,05H,00H,00H,00H,80H,0FCH,0A1HDB24H,0A1H,24H,0A1H,0FCH,0FFH,24H,0A1HDB24H,0B1H,0FEH,0A1H,04H,80H,00H,80HTAB8:DB00H,00H,00H,10H,08H,10H,08H,10H;“工”字點(diǎn)陣數(shù)據(jù)DB08H,10H,08H,10H,08H,10H,0F8H,1FHDB08H,10H,08H,10H,08H,10H,08H,10HDB08H,10H,00H,10H,00H,00H,00H,00HTAB9:DB00H,00H,40H,40H,40H,40H,40H,20H;“大”字點(diǎn)陣數(shù)據(jù)DB40H,10H,40H,0CH,40H,03H,0FCH,00HDB40H,03H,40H,0CH,40H,10H,40H,20HDB40H,60H,40H,40H,40H,40H,00H,00HTAB10:DB00H,00H,40H,00H,30H,00H,14H,04H;“學(xué)”字點(diǎn)陣數(shù)據(jù)DB18H,04H,50H,04H,50H,24H,54H,44HDB58H,3FH,50H,05H,0D4H,04H,16H,04HDB10H,04H,50H,04H,30H,00H,00H,00H第四章：系統(tǒng)程序設(shè)計(jì)一．主程序ORG0000HMAIN:MOVR6,#10H;設(shè)置“歡”字顯示的延時(shí)時(shí)間常數(shù)HUANZ:LCALLHSUB；調(diào)“歡”字的子程序DJNZR6,HUANZ；判斷顯示延時(shí)時(shí)間到否MOVR7,#10H；設(shè)置“迎”字顯示的延時(shí)時(shí)間常數(shù)YINGZ:LCALLYSUB；調(diào)“迎”字的子程序DJNZR7,YINGZ；判斷顯示延時(shí)時(shí)間到否MOVR6,#10H；設(shè)置“光”字顯示的延時(shí)時(shí)間常數(shù)GUANG:LCALLGSUB；調(diào)“光”字的子程序DJNZR6,GUANG；判斷顯示延時(shí)時(shí)間到否MOVR7,#10H；設(shè)置“臨”字顯示的延時(shí)時(shí)間常數(shù)LIN:LCALLLSUB；調(diào)“臨”字的子程序DJNZR7,LIN；判斷顯示延時(shí)時(shí)間到否MOVR6,#10H;設(shè)置“武”字顯示的延時(shí)時(shí)間常數(shù)WU:LCALLWSUB;調(diào)“武”字的子程序DJNZR6,WU;判斷顯示延時(shí)時(shí)間到否MOVR7,#10H;設(shè)置“漢”字顯示的延時(shí)時(shí)間常數(shù)HAN:LCALLASUB;調(diào)“漢”字的子程序DJNZR7,HAN;判斷顯示延時(shí)時(shí)間到否MOVR6,#10H;設(shè)置“理”字顯示的延時(shí)時(shí)間常數(shù)LI:LCALLLLSUB;調(diào)“理”字的子程序DJNZR6,LI;判斷顯示延時(shí)時(shí)間到否MOVR7,#10H;設(shè)置“工”字顯示的延時(shí)時(shí)間常數(shù)GONG:LCALLGGSUB;調(diào)“工”字的子程序DJNZR7,GONG;判斷顯示延時(shí)時(shí)間到否MOVR6,#10H;設(shè)置“大”字顯示的延時(shí)時(shí)間常數(shù)DAZ:LCALLDSUB;調(diào)“大”字的子程序DJNZR6,DAZ;判斷顯示延時(shí)時(shí)間到否MOVR7,#10H;設(shè)置“學(xué)”字顯示的延時(shí)時(shí)間常數(shù)XUE:LCALLXSUB;調(diào)“學(xué)”字的子程序DJNZR7,XUE;判斷顯示延時(shí)時(shí)間到否AJMPMAIN；程序循環(huán)執(zhí)行二．“歡”字顯示子程序HSUB:MOVR5,#00H；“歡”字顯示子程序開(kāi)始，顯示數(shù)據(jù)計(jì)數(shù)器置初值MOVR1,#0FEH；前八列數(shù)據(jù)顯示，選中第一列HSUB0:MOVDPTR,#0DFFFH；DFFFH為3#鎖存器的地址MOVA,R1MOVX@DPTR,AMOVDPTR,#0EFFFH；EFFFH為4#鎖存器的地址MOVA,#0FFHMOVX@DPTR,A；將第一列的點(diǎn)陣數(shù)據(jù)的上半部分送入LEDMOVDPTR,#TAB1MOVA,R5MOVCA,@A+DPTRMOVDPTR,#7FFFH；7FFFH為1#鎖存器的地址MOVX@DPTR,AINCR5MOVA,R5MOVDPTR,#TAB1；將第一列的點(diǎn)陣數(shù)據(jù)的下半部分送入LEDMOVCA,@A+DPTRMOVDPTR,#0BFFFH；BFFFH為2#鎖存器的地址MOVX@DPTR,ALCALLDY1MS；調(diào)延時(shí)一秒子程序MOVA,R1；準(zhǔn)備選中下一列RLAMOVR1,AINCR5CJNER5,#10H,HSUB0；判斷前8列顯示完否，如果沒(méi)有完繼續(xù)顯示MOVR1,#0FEH；后八列數(shù)據(jù)顯示HSUB1:MOVDPTR,#0EFFFHMOVA,R1MOVX@DPTR,AMOVDPTR,#0DFFFHMOVA,#0FFHMOVX@DPTR,AMOVDPTR,#TAB1MOVA,R5MOVCA,@A+DPTRMOVDPTR,#7FFFHMOVX@DPTR,AINCR5MOVA,R5MOVDPTR,#TAB1MOVCA,@A+DPTRMOVDPTR,#0BFFFHMOVX@DPTR,ALCALLDY1MSMOVA,R1RLAMOVR1,AINCR5CJNER5,#20H,HSUB1RET三．“迎”字顯示子程序YSUB:MOVR5,#00H；“迎”字顯示子程序MOVR1,#0FEHYSUB0:MOVDPTR,#0DFFFHMOVA,R1MOVX@DPTR,AMOVDPTR,#0EFFFHMOVA,#0FFHMOVX@DPTR,AMOVDPTR,#TAB2MOVA,R5MOVCA,@A+DPTRMOVDPTR,#7FFFHMOVX@DPTR,AINCR5MOVA,R5MOVDPTR,#TAB2MOVCA,@A+DPTRMOVDPTR,#0BFFFHMOVX@DPTR,ALCALLDY1MSMOVA,R1RLAMOVR1,AINCR5CJNER5,#10H,YSUB0MOVR1,#0FEHYSUB1:MOVDPTR,#0EFFFHMOVA,R1MOVX@DPTR,AMOVDPTR,#0DFFFHMOVA,#0FFHMOVX@DPTR,AMOVDPTR,#TAB2MOVA,R5MOVCA,@A+DPTRMOVDPTR,#7FFFHMOVX@DPTR,AINCR5MOVA,R5MOVDPTR,#TAB2MOVCA,@A+DPTRMOVDPTR,#0BFFFHMOVX@DPTR,ALCALLDY1MSMOVA,R1RLAMOVR1,AINCR5CJNER5,#20H,YSUB1RET四．“光”字顯示子程序GSUB:MOVR5,#00H；“光”字顯示子程序開(kāi)始，顯示數(shù)據(jù)計(jì)數(shù)器置初值MOVR1,#0FEH；前八列數(shù)據(jù)顯示，選中第一列GSUB0:MOVDPTR,#0DFFFH；DFFFH為3#鎖存器的地址MOVA,R1MOVX@DPTR,A；EFFFH為4#鎖存器的地址MOVDPTR,#0EFFFHMOVA,#0FFHMOVX@DPTR,A；將第一列的點(diǎn)陣數(shù)據(jù)的上半部分送入LEDMOVDPTR,#TAB3MOVA,R5MOVCA,@A+DPTRMOVDPTR,#7FFFH；7FFFH為1#鎖存器的地址MOVX@DPTR,AINCR5MOVA,R5MOVDPTR,#TAB3；將第一列的點(diǎn)陣數(shù)據(jù)的下半部分送入LEDMOVCA,@A+DPTR；BFFFH為2#鎖存器的地址MOVDPTR,#0BFFFHMOVX@DPTR,ALCALLDY1MS；調(diào)延時(shí
