【導(dǎo)讀】利用實(shí)驗(yàn)上的液晶顯示屏電路，編寫程序控制顯示，輸出漢字或字符。．了解點(diǎn)陣漢子的顯示原理。點(diǎn)亮滅的方法稱為靜態(tài)驅(qū)動(dòng)顯示方式。16ｘ16的點(diǎn)陣共有256個(gè)發(fā)光二極管，顯然單片機(jī)。陣需要256/8=32個(gè)鎖存器。這個(gè)數(shù)字很龐大，因?yàn)槲覀儍H僅是16ｘ16的點(diǎn)陣，在實(shí)際應(yīng)用。用中的顯示屏幾乎都不采用這種設(shè)計(jì)，而采用另外一種稱為動(dòng)態(tài)掃描的顯示方法?，F(xiàn)同名列共用一套驅(qū)動(dòng)器。具體就16ｘ16的點(diǎn)陣來(lái)說(shuō)，把所有同1行。經(jīng)過(guò)上述分析，可以歸納出列。對(duì)于列數(shù)據(jù)準(zhǔn)備來(lái)說(shuō)，它應(yīng)能實(shí)現(xiàn)串入并出的移。位功能；對(duì)于列數(shù)據(jù)顯示來(lái)說(shuō)，應(yīng)具有并行鎖存的功能。顯示時(shí)，串并移位寄存器就可以準(zhǔn)備下一行的列數(shù)據(jù)而不影響本行的顯示。及相應(yīng)的程序的運(yùn)行、以及給屏體電路部分發(fā)送命令。同時(shí)內(nèi)含2個(gè)外中斷口，2個(gè)16位可編程定時(shí)計(jì)數(shù)器，2個(gè)全雙工串行通信口，其將通用的微處理器和。在由外部程序存儲(chǔ)器取指期間，每個(gè)機(jī)。沖觸發(fā)，低電平清除，常用作8位地址鎖存器。
