【正文】 Design of Led advertising display based on Abstract LED display is information media is the key of the new century, has a key to use in a variety of industries. Many supermarkets appearance decoration, bank rolling screen prompts,train station ticket points, LED displays are everywhere. The most mon structure of LED display screen, some products factory, manufacturers have fixed material inside, so the design relatively low price is also more streamlined. Also has an electronic screen hasreserved the readwrite port, the user after the purchase, can according to their own needs, in accordance with the instructions that modify the contents of their own needs, letLED display more flexible and universal. Keywords: AT89C52, LED matrix display, microcontroller 目錄 1 前言 ............................................................................................................................. 6 本設(shè)計(jì)的目的、意義及應(yīng)達(dá)到的技術(shù)要求 ............................................................ 6 本設(shè)計(jì)在國(guó)內(nèi)外的發(fā)展概況及存在的問(wèn)題 ............................................................ 6 本設(shè)計(jì)應(yīng)解決的主要問(wèn)題 ..................................................................................... 7 2 本設(shè)計(jì) .......................................................................................................................... 7 設(shè)計(jì)原理 ............................................................................................................. 7 單片機(jī)系統(tǒng)及其外圍電路 ........................................................................... 8 行驅(qū)動(dòng)電路 ................................................................................................ 8 列驅(qū)動(dòng)電路 ................................................................................................ 9 主要元器件介紹 ................................................................................................... 9 88 的點(diǎn)陣 led 的結(jié)構(gòu) ................................................................................ 9 74LS595芯片介紹 ................................................................................. 10 74LS164芯片介紹 .................................................................................... 11 AT89C52芯片介 ....................................................................................... 12 單片機(jī)的最小 系統(tǒng) ................................................................................... 13 程序 ................................................................................................................. 14 顯示驅(qū)動(dòng)程序 .......................................................................................... 14 LED的顯示方式 ....................................................................................... 14 ............................................................................................ 16 調(diào)試以及性能分析 ............................................................................................ 17 硬件調(diào)試 .................................................................................................. 17 軟件調(diào)試 .................................................................................................. 17 3 結(jié)論 ........................................................................................................................... 18 參考文獻(xiàn) ........................................................................................................................ 19 謝 辭 ....................................................................................................
