8、weep。08Interface引言自20世紀(jì)80年代后期開始，隨著LED制造技術(shù)的不斷完善，在國(guó)外得到了廣泛的應(yīng)用。在我國(guó)改革開放之后，提別是進(jìn)入90年代國(guó)民經(jīng)濟(jì)的高速增長(zhǎng)，對(duì)公眾場(chǎng)合發(fā)布信息的需求日益強(qiáng)烈。而LED顯示屏作為信息傳播的一種重要手段，已經(jīng)成為城市信息現(xiàn)代化建設(shè)的標(biāo)志,LED顯示屏隨著社會(huì)經(jīng)濟(jì)的不斷進(jìn)步，以及LED制造技術(shù)的完善，人們對(duì)LED顯示屏的認(rèn)識(shí)將會(huì)越來(lái)越深入，其應(yīng)用領(lǐng)域?qū)?huì)越來(lái)越廣；LED顯示屏經(jīng)多年的開發(fā)、研制、生產(chǎn)，其技術(shù)目前已經(jīng)成熟?，F(xiàn)在各種廣告牌不再是白底黑字了，也不再是單一的非電產(chǎn)品，而是用上了豐富多彩的LED電子產(chǎn)品，為城市的增添了一道靚麗的風(fēng)景。而且它采

9、用低電壓掃描驅(qū)動(dòng)，具有耗電少、使用壽命長(zhǎng)、成本低、發(fā)光效率高、故障少、視角大、可視距離遠(yuǎn)、可靠耐用、組態(tài)靈活、安全、響應(yīng)時(shí)間短、綠色環(huán)保、控制靈活、色彩豐富以及對(duì)室內(nèi)外環(huán)境適應(yīng)能力強(qiáng)等特點(diǎn)。近年來(lái)LED顯示屏市場(chǎng)得到了迅猛的發(fā)展，已經(jīng)廣泛應(yīng)用到銀行、郵電、稅務(wù)、機(jī)場(chǎng)、車站、證券市場(chǎng)及其它交易市場(chǎng)、醫(yī)院、電力、海關(guān)、體育場(chǎng)等需要進(jìn)行多種公告、宣傳的場(chǎng)合。因此，學(xué)習(xí)LED系統(tǒng)原理與工程技術(shù)很有必要。通過設(shè)計(jì)一個(gè)可顯示文字與圖形的16*64點(diǎn)陣控制器來(lái)學(xué)習(xí)和熟悉LED的使用。1系統(tǒng)的設(shè)計(jì)與分析本文是通過設(shè)計(jì)一個(gè)可顯示文字與圖形的16*64點(diǎn)陣控制器電路來(lái)學(xué)習(xí)和熟悉LED的使用，LED點(diǎn)陣控制器分為五

15、一直是在門外看，沒有真正深入進(jìn)去實(shí)際操作，只是對(duì)顯示原理有個(gè)大概的了解；本來(lái)計(jì)劃將時(shí)鐘、亮度、溫度加入到整個(gè)系統(tǒng)中來(lái)，這樣就更加接近實(shí)際應(yīng)用，但是由于時(shí)間的關(guān)系，只做了串口通訊部分進(jìn)去，而且功能也較為簡(jiǎn)單。在調(diào)試串口通訊花的時(shí)候是最多的，主要是因?yàn)榇谕ㄓ嵭酒c單片機(jī)的連接錯(cuò)誤，導(dǎo)致無(wú)法通訊。在整個(gè)實(shí)訓(xùn)過程中，真正能學(xué)到東西的是調(diào)試，雖然我們平常使用的Proteus仿真軟件也與實(shí)際差距越來(lái)越小，但是理論與實(shí)際的還是有相當(dāng)?shù)牟煌?，最關(guān)鍵的是發(fā)現(xiàn)問題，并解決問題，這樣會(huì)對(duì)以后的學(xué)習(xí)中都有較大的幫助。除此之外，在實(shí)訓(xùn)的過程中與其它同學(xué)之間互相溝通與交流，通過學(xué)習(xí)其它的設(shè)計(jì)思路，發(fā)現(xiàn)其優(yōu)點(diǎn)及缺點(diǎn)，然后

16、一起討論，這有利于提高我們的綜合能力，為以后走上好的工作崗位打下堅(jiān)實(shí)的基礎(chǔ)。謝辭實(shí)訓(xùn)臨近結(jié)束了，在此過程中很多同學(xué)和老師都在耐心的幫助我。衷心感謝老師的悉心指導(dǎo)和同學(xué)們的熱情幫助，在我實(shí)訓(xùn)完成過程中，老師同學(xué)提供了許多寶貴意見，讓我學(xué)到了許多知識(shí)，開闊了眼界，增強(qiáng)了我的動(dòng)手和動(dòng)腦能力。同時(shí)，感激06級(jí)師兄的幫助，有了他們耐心的指導(dǎo)我做板，我才能在規(guī)定的時(shí)間完成這次實(shí)訓(xùn)，并從中學(xué)到了更多的知識(shí)。我水平有限，所以這次設(shè)計(jì)還存在著許多不盡如人意的地方，歡迎老師和同學(xué)批評(píng)指正。此外，還要感謝我們學(xué)院為我們提供這個(gè)機(jī)會(huì)和必要物質(zhì)支持。參考文獻(xiàn)陳孟建等編著.C語(yǔ)言程序設(shè)計(jì)電子工業(yè)出版社,2006.6:19
