Complete machine 40 foot monolithic integrated circuit AT89C51 which produces by American ATMEL Corporation is a core, introduced take it as the control system LED lattice electron display monitor dynamic design and the performance good driver 74HC154 and four row driver 74HC595 through this chip actuates the display monitor electronic display monitor may demonstrate each kind of language or the monochrome picture, the entire screen can demonstrate 2 Chinese characters, use 8 88 lattice LED demonstration module to pose 1632 the lattice demonstration demonstration uses the dynamic demonstration, causes the graph or the writing can realize static, moves in the emigration and so on many kinds of display the article in detail introduced the LED lattice demonstration hardware design mentality, hardware electric circuit each part of function and the principle, the corresponding software programming, as well as operating instructions and so on. SCM control system using microcontroller C language program for editing, the corresponding LED anode and cathode terminal programmed to control the level of each display point, you can effectively control each display point of light off. The dot matrix display data characters can prepare themselves (ie direct dot drawing), can also be extracted from the standard font. LED display with its flexible fabric, show stable, low power consumption, long service life, mature technology, low cost, etc in the station, securities, sports venues, the traffic trunk road, and various kinds of indoor/outdoor display of information release, public welfare propaganda, environmental parameters in realtime, major events countdown, etc widely used. The practice has proved that the system displays error is small, stable performance, reasonable structure, strong expansion capability. Keywords: AT89C51 monolithic integrated circuit。 LED。 Lattice demonstration。 Dynamic demonstration。 C language. 錯(cuò)誤 !未指定書(shū)簽。 3 目錄 第 1 章 緒 論 .................................................................................................... 1 設(shè)計(jì)課題背景 及意義 ....................................................................................................... 1 設(shè)計(jì)的主要內(nèi)容 ............................................................................................................... 2 第 2 章 設(shè)計(jì)框圖及介紹 .................................................................................. 3 第 3 章 硬件設(shè)計(jì) .............................................................................................. 4 電源電路 ........................................................................................................................... 4 復(fù)位電路 .......................................................................................................................................................... 4 單片機(jī)應(yīng)用系統(tǒng) .............................
