1、摘要LCD液晶顯示已經(jīng)是人機界面的關(guān)鍵技術(shù)。本文對基于單片機的LCD液晶顯示器控制系統(tǒng)進行了研究。首先在緒論中介紹了本課題的課題背景、研究意義及完成的功能。本系統(tǒng)是以單片機的基本語言C語言來進行軟件設(shè)計,51的編程語言常用的有二種,一種是匯編語言,一種是C語言。匯編語言的機器代碼生成效率很高但可讀性卻并不強,復(fù)雜一點的程序就更是難讀懂,而C語言在大多數(shù)情況下其機器代碼生成效率和匯編語言相當,但可讀性和可移植性卻遠遠超過匯編語言,而且C語言還可以嵌入?yún)R編來解決高時效性的代碼編寫問題。對于開發(fā)周期來說,中大型的軟件編寫用C語言的開發(fā)周期通常要小于匯編
2、語言很多。綜合以上C語言的優(yōu)點,我在學(xué)習(xí)時選擇了C語言指令的執(zhí)行速度快,節(jié)省存儲空間。為了便于擴展和更改,軟件的設(shè)計采用模塊化結(jié)構(gòu),使程序設(shè)計的邏輯關(guān)系更加簡潔明了。使硬件在軟件的控制下協(xié)調(diào)運作。正文中首先簡單描述系統(tǒng)硬件工作原理,且附以系統(tǒng)硬件設(shè)計框圖,并介紹了單片機微處理器的發(fā)展史,論述了本次畢業(yè)設(shè)計所應(yīng)用的各硬件接口技術(shù)和各個接口模塊的功能及工作過程,并具體描述了AT89C51AMPIRE128×64接電路接口的軟、硬件調(diào)試。其次闡述了程序的流程和實現(xiàn)過程。本文撰寫的主導(dǎo)思想是軟、硬件相結(jié)合,以硬件為基礎(chǔ),來進行各功能模塊的編寫。最后對我所
