1、摘要單片機(jī)是一種集成電路芯片,采用超大規(guī)模技術(shù)把具有數(shù)據(jù)處理能力(如算術(shù)運(yùn)算,邏輯運(yùn)算、數(shù)據(jù)傳送、中斷處理)的微處理器(CPU)。隨著單片機(jī)技術(shù)的飛速發(fā)展,各種單片機(jī)蜂擁而至,單片機(jī)技術(shù)已成為一個國家現(xiàn)代化科技水平的重要標(biāo)志。單片機(jī)可單獨(dú)地完成現(xiàn)代工業(yè)控制所要求的智能化控制功能,這是單片機(jī)最大的特征。單片機(jī)控制系統(tǒng)能夠取代以前利用復(fù)雜電子線路或數(shù)字電路構(gòu)成的控制系統(tǒng),可以軟件控制來實(shí)現(xiàn),并能夠?qū)崿F(xiàn)智能化?,F(xiàn)在單片機(jī)控制范疇無所不在,例如通信產(chǎn)品、家用電器、智能儀器儀表、過程控制和專用控制裝置等等,單片機(jī)的應(yīng)用領(lǐng)域越來越
2、廣泛。本畢業(yè)設(shè)計(jì)的課題是“簡易數(shù)字電壓表的設(shè)計(jì)”。主要考核我們對單片機(jī)技術(shù),編程能力等方面的情況。觀察獨(dú)立分析、設(shè)計(jì)單片機(jī)的能力,以及實(shí)際編程技能。本課題主要解決A/D轉(zhuǎn)換、數(shù)據(jù)處理及顯示控制等三個模塊??刂葡到y(tǒng)采用AT89C52單片機(jī),A/D轉(zhuǎn)換采用ADC0809。??關(guān)鍵字介紹:單片機(jī),AT89C52,A/D轉(zhuǎn)換,ADC0809,數(shù)據(jù)處理。AbstractChipProcessorisakindofchipofintegratedcircuit,adopttoexceedlarge-scaletechnologyh
