可以直接顯示漢字的19264液晶驅(qū)動(dòng)C語言程序

1、注：本程序是經(jīng)過KEIL編譯通過，并通過實(shí)驗(yàn)板測(cè)試通過的，直接按硬件電路連接好顯示屏然后將程序代碼燒寫入單片機(jī)即可點(diǎn)亮，將顯示武漢2字，并且隨意設(shè)置坐標(biāo)，就可以在不同的位置顯示，使用很方便。如果不能顯示請(qǐng)將軟件中的接口定義按照本電路圖中的定義修改一下即可。19264液晶顯示屏的硬件連接圖jTfiE2j?a7nsTri?jyb75SFOILTEH-ri9亠.TjTnPIOPXi3.IIJJ45聆_.Ta1JTi111FrrrrrrPP2.-P2?22如P24MH?!*1*1*1*1*1*1*1*1*1*1*、t*、t*、t*、t*、t*、t*、t*、t*kJ*1*1*/rTrr*rTrTrTw#
