1、內(nèi)蒙古科技大學(xué)本科生畢業(yè)設(shè)計(jì)說(shuō)明書(shū)(畢業(yè)論文)題目:51系列單片機(jī)教學(xué)實(shí)驗(yàn)板硬件設(shè)計(jì)學(xué)生姓名:李國(guó)棟學(xué)號(hào):200540503313專(zhuān)業(yè):測(cè)控技術(shù)與儀器班級(jí):測(cè)控05-3指導(dǎo)教師:肖俊生59內(nèi)蒙古科技大學(xué)畢業(yè)設(shè)計(jì)說(shuō)明書(shū)(畢業(yè)論文)51系列單片機(jī)教學(xué)實(shí)驗(yàn)板硬件設(shè)計(jì)摘要在全國(guó)高等院校電子信息類(lèi)專(zhuān)業(yè)中,已普遍開(kāi)設(shè)單片機(jī)及其相關(guān)課程。單片機(jī)課程是大中專(zhuān)院校電子類(lèi)專(zhuān)業(yè)實(shí)踐性、應(yīng)用性和工程性很強(qiáng)的專(zhuān)業(yè)基礎(chǔ)課或?qū)I(yè)選修課。從加強(qiáng)學(xué)生能力培養(yǎng)的要求來(lái)看,這類(lèi)課程僅在課堂上講授基本原理是不夠的,必須在教學(xué)中加強(qiáng)實(shí)踐環(huán)節(jié),讓學(xué)生有足夠
2、的實(shí)踐機(jī)會(huì)。其中,單片機(jī)實(shí)驗(yàn)板就是一個(gè)很好的學(xué)習(xí)單片機(jī)的工具。目前,市場(chǎng)上單片機(jī)實(shí)驗(yàn)板的種類(lèi)較多。此次設(shè)計(jì)的實(shí)驗(yàn)板的特點(diǎn)是將各種單元電路合理的拼湊在一塊大印刷電路板上,構(gòu)成一個(gè)有機(jī)的整體。設(shè)計(jì)中利用Protel99SE軟件先設(shè)計(jì)原理圖,然后進(jìn)行元件封裝,PCB出圖,最后是制板。它與傳統(tǒng)的教學(xué)實(shí)驗(yàn)板相比有如下的優(yōu)點(diǎn):⑴價(jià)格低廉;⑵使用簡(jiǎn)單方便,只要有帶RS232串口的PC機(jī)就能進(jìn)行實(shí)驗(yàn);⑶功能全,基本上具備單片機(jī)常用的接口,如數(shù)模轉(zhuǎn)換、模數(shù)轉(zhuǎn)換、存儲(chǔ)器、LED數(shù)碼管顯示、鍵盤(pán)人機(jī)接口、串行接口、溫度傳感器接口等等。
3、采用本仿真開(kāi)發(fā)實(shí)驗(yàn)板,可使初學(xué)者迅速掌握單片機(jī)原理及應(yīng)用,熟悉匯編語(yǔ)言、單片機(jī)C語(yǔ)言。關(guān)鍵詞:?jiǎn)纹瑱C(jī);實(shí)驗(yàn)板;接口電路;C語(yǔ)言59內(nèi)蒙古科技大學(xué)畢業(yè)設(shè)計(jì)說(shuō)明書(shū)(畢業(yè)論文)51SeriesSingle-chipTeachingExperimentalBoardHardwareDesignAbstractNationalinstitutionsofhigherlearningintheprofessionalcategoryofelectronicinformation,hasgenerallybeenthecrea
