【導(dǎo)讀】本設(shè)計使用AT89C51系列高速單片機(jī)作為主控制模塊，利用簡單的外圍電路來驅(qū)動64×16. 的點(diǎn)陣LED顯示屏。利用AT89C51系列高速單片機(jī)本身強(qiáng)大的功能，可以很方便的實(shí)現(xiàn)單片機(jī)與PC機(jī)間。院、機(jī)場、銀行等公共場所，所以本設(shè)計具有很強(qiáng)的現(xiàn)實(shí)應(yīng)用性。本LED顯示屏能夠以動態(tài)掃描的方式同時顯示4個16×16點(diǎn)陣漢字，并能通過上位機(jī)軟件修改顯示內(nèi)。容和顯示效果等等。把字符內(nèi)碼存儲在空閑的單片機(jī)程序存儲器空間，使本LED顯示系統(tǒng)能掉電存儲1024. 設(shè)計中采用了SPI接口的GB2312標(biāo)準(zhǔn)字庫，支持所有的國標(biāo)字符和ASCII標(biāo)準(zhǔn)字符的顯示。為采用串行傳輸方式，使本系統(tǒng)的可擴(kuò)展性得到提升，便于多個顯示單元的級聯(lián)。
