51單片機摘要
Abstract
In recent years along with the computer in the social domain seepage and the large scale integrated circuit development, the monolithic integrated circuit application was moving towards unceasingly thoroughly, because it had function, the volume was small, the power loss was low, the price was cheap, the work was reliable, characteristics and so on easy to operate, therefore suited specially in with the control related system, more and more widely applied in the automatic control, the intellectualized instrument, the measuring appliance, the data acquisition, the military proct as well as the domestic electric appliances and so on each domain, the monolithic integrated circuit often is took a core part used, in the basis concrete hardware architecture, as well as in view of the concrete application object characteristic software union, made the consummation.
Along with take the computer as the axle center various information processing installment birth, for will adapt this kind of new situation, the information electrical appliances, the network termination, use and so on broadcast - correspondence LCD markets is also rapid expands, not only moreover the present LCD development direction lies in the large screen, moreover in the small screen aspect, for example the automobile guidance system, the camera, the digital photographic camera, the portable television, PDA (personal digital assistant), the entertainment/mechanical games, the camera and so on has the further development.
Liquid-crystal display (LCD) has the merit which the power loss low, the volume small, the weight light, ultra thin and so on many other monitors are unable to compare, in recent years widely uses in the intelligent instrument, the measuring appliance and the low power loss electronic procts which the monolithic integrated circuit controls .LCD may divide into section type LCD, character type LCD and among lattice type LCD., section type LCD and character type LCD only can use in the character and the digital simple demonstration, cannot satisfy the graph curve and the Chinese character demonstration request; Not only but lattice type LCD may demonstrate the character, the numeral, but also may demonstrate each kind of graph, the curve as well as the Chinese character, the animation, and may realize functions and so on screen trundle, reverse, twinkle, the use is extremely widespread.
Thus it can be seen the LCD application is so widespread, therefore controls the liquid-crystal display with MPU is the very universal application. This topic main research realizes the liquid crystal mole character demonstration through the monolithic integrated circuit control.

㈣ 關於51單片機 的秒錶/時鍾計時器設計摘要
數字電子秒錶具有顯示直觀、讀取方便、精度高等優點，在計時中廣泛使用。本設計用單片機組成數字電子秒錶，力求結構簡單、精度高為目標。
設計中包括硬體電路的設計和系統程序的設計。其硬體電路主要有主控制器，計時與顯示電路和回零、啟動和停表電路等。主控制器採用單片機AT89C52，顯示電路採用共陰極LED數碼管顯示計時時間。
本設計利用AT89C52單片機的定時器/計數器定時和記數的原理，使其能精確計時。利用中斷系統使其能實現開始暫停的功能。P0口輸出段碼數據，P2.0-P2.4口作列掃描輸出，P1.1、P3.2、P3.3、P2.5口接四個按鈕開關，分別實現開始、暫停、清零和查看上次計時時間功能。電路原理圖設計最基本的要求是正確性，其次是布局合理，最後在正確性和布局合理的前提下力求美觀。硬體電路圖按照圖1.1進行設計。
圖1.1 數字秒錶硬體電路基本原理圖
根據要求知道秒錶設計主要實現的功能是計時和顯示。因此設置了四個按鍵和五位數碼管顯示時間，三個按鍵分別是開始，停止、復位和查看上次計時時間按鍵。利用這四個建來實現秒錶的全部功能，而五位數碼管則能顯示最多99.999秒的計時。
本設計中，數碼管顯示的數據存放在內存單元79H－7DH中。其中79H存放毫秒位數據，7AH存放十毫秒位數據，7BH存放百毫秒位數據，7CH存放秒位數據，7DH存放十秒位數據，每一地址單元內均為十進制BCD碼。由於採用軟體動態掃描實現數據顯示功能，顯示用十進制BCD碼數據的對應段碼存放在ROM表中。顯示時，先取出79H-7dH某一地址中的數據，然後查得對應的顯示用段碼，並從P0口輸出，P2口將對應的數碼管選中供電，就能顯示該地址單元的數據值。
最終緩存區則設置為59H-5DH，數據存放規則和79H-7DH一樣。分別對應存放毫秒位至十秒位數據。與79H-7DH存儲區不一樣的是：59H-5DH存儲的內容為數字秒錶上一次計時顯示的時間。而79H-7DH為當前計時時間存儲區。
計時採用定時器T0中斷完成，定時溢出中斷周期為1ms，當一處中斷後向CPU發出溢出中斷請求，每發出一次中斷請求就對毫秒計數單元進行加一，達到10次就對十毫秒位進行加一，依次類推，直到99.999秒重新復位。
再看按鍵的處理。這四個鍵可以採用中斷的方法，也可以採用掃描的方法來識別。復位鍵和查看主要功能在於數值復位和查詢上次計時時間，對於時間的要求不是很嚴格。而開始和停止鍵則是用於對時間的鎖定，需要比較准確的控制。因此可以對復位和查看按鍵採取掃描的方式。而對開始和停止鍵採用外部中斷的方式。
設計中包括硬體電路的設計和系統程序的設計。其硬體電路主要有主控制器，顯示電路和回零、啟動、查看、停表電路等。主控制器採用單片機AT89C52，顯示電路採用共陰極LED數碼管顯示計時時間，四個按鍵均採用觸點式按鍵。
對於數字顯示電路，通常採用液晶顯示或數碼管顯示。對於一般的段式液晶屏，需要專門的驅動電路，而且液晶顯示作為一種被動顯示，可視性差，不適合遠距離觀看；對於具有驅動電路和單片機介面的液晶顯示模塊(字元或點陣)，一般多採用並行介面，對單片機的介面要求較高，佔用資源多；另外，AT89S52單片機本身無專門的液晶驅動介面。而數碼管作為一種主動顯示器件，具有亮度高、響應速度快、防潮防濕性能好、溫度特性極性、價格便宜、易於購買等優點，而且有遠距離視覺效果，很適合夜間或是遠距離操作。因此，本設計的顯示電路採用7段數碼管作為顯示介質。
數碼管顯示可以分為靜態顯示和動態顯示兩種。由於本設計需要採用五位數碼管顯示時間，如果靜態顯示則佔用的口線多，硬體電路復雜。所以採用動態顯示。
圖1.3 顯示電路基本原理圖
動態顯示是一位一位地輪流點亮各位數碼管，這種逐位點亮顯示器的方式稱為位掃描。通常各位數碼管的段選線相應並聯在一起，由一個8位的I/O口控制；各位的公共陰極位選線由另外的I/O口線控制。動態方式顯示時，各數碼管分時輪流選通，要使其穩定顯示必須採用掃描方式，即在某一時刻只選通一位數碼管，並送出相應的段碼，在另一時刻選通另一位數碼管，並送出相應的段碼，依此規律循環，即可使各位數碼管顯示將要顯示的字元，雖然這些字元是在不同的時刻分別顯示，但由於人眼存在視覺暫留效應，只要每位顯示間隔足夠短就可以給人同時顯示的感覺。
數碼顯示管分為共陽數碼管和共陰數碼管兩種
共陽極數碼管的8個發光二極體的陽極（二極體正端）連接在一起，如圖1.4（b），通常，公共陽極接高電平（一般接電源），其它管腳接段驅動電路輸出端。當某段驅動電路的輸出端為低電平時，則該端所連接的欄位導通並點亮，根據發光欄位的不同組合可顯示出各種數字或字元。此時，要求段驅動電路能吸收額定的段導通電流，還需根據外接電源及額定段導通電流來確定相應的限流電阻。
共陰極數碼管的8個發光二極體的陰極（二極體負端）連接在一起，如圖（c），通常，公共陰極接低電平（一般接地），其它管腳接段驅動電路輸出端，當某段驅動電路的輸出端為高電平時，則該端所連接的欄位導通並點亮，根據發光欄位的不同組合可顯示出各種數字或字元。此時，要求段驅動電路能提供額定的段導通電流，還需根據外接電源及額定段導通電流來確定相應的限流電阻。
㈤ 單片機摘要怎麼寫
摘 要
LCD液晶顯示已經是人機界面的關鍵技術。本文對基於單片機的LCD液晶顯示器控制系統進行了研究。
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。本系統是以單片機的基本語言C語言來進行軟體設計，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並不強，復雜一點的程序就更是難讀懂，而C 語言在大多數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 語言還可以嵌入匯編來解決高時效性的代碼編寫問題。對於開發周期來說，中大型的軟體編寫用C 語言的開發周期通常要小於匯編語言很多。綜合以上C 語言的優點，我在學習時選擇了C 語言指令的執行速度快，節省存儲空間。為了便於擴展和更改，軟體的設計採用模塊化結構，使程序設計的邏輯關系更加簡潔明了。使硬體在軟體的控制下協調運作。正文中首先簡單描述系統硬體工作原理，且附以系統硬體設計框圖，並介紹了單片機微處理器的發展史，論述了本次畢業設計所應用的各硬體介面技術和各個介面模塊的功能及工作過程, 並具體描述了AT89C51 AMPIRE128×64接電路介面的軟、硬體調試。其次闡述了程序的流程和實現過程。本文撰寫的主導思想是軟、硬體相結合，以硬體為基礎，來進行各功能模塊的編寫。
最後對我所開發的用單片機實現LCD液晶顯示器控制原理的設計思想和軟、硬體調試作了詳細的論述。
