可以直接顯示漢字的19264液晶驅(qū)動C語言程序

1、注：本程序是經(jīng)過KEIL編譯通過，并通過實驗板測試通過的，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即可點亮，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#
