【導(dǎo)讀】利用實驗上的液晶顯示屏電路，編寫程序控制顯示，輸出漢字或字符。．了解點陣漢子的顯示原理。點亮滅的方法稱為靜態(tài)驅(qū)動顯示方式。16ｘ16的點陣共有256個發(fā)光二極管，顯然單片機(jī)。陣需要256/8=32個鎖存器。這個數(shù)字很龐大，因為我們僅僅是16ｘ16的點陣，在實際應(yīng)用。用中的顯示屏幾乎都不采用這種設(shè)計，而采用另外一種稱為動態(tài)掃描的顯示方法?，F(xiàn)同名列共用一套驅(qū)動器。具體就16ｘ16的點陣來說，把所有同1行。經(jīng)過上述分析，可以歸納出列。對于列數(shù)據(jù)準(zhǔn)備來說，它應(yīng)能實現(xiàn)串入并出的移。位功能；對于列數(shù)據(jù)顯示來說，應(yīng)具有并行鎖存的功能。顯示時，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。同時內(nèi)含2個外中斷口，2個16位可編程定時計數(shù)器，2個全雙工串行通信口，其將通用的微處理器和。在由外部程序存儲器取指期間，每個機(jī)。沖觸發(fā)，低電平清除，常用作8位地址鎖存器。
