　　　　　摘要
　　　
　　　單片機自20世紀(jì)70年代問世以來，以極其高的性價比受到人們的重視和關(guān)注，所以應(yīng)用很廣，發(fā)展很快。單片機的優(yōu)點是體積小、重量輕、抗干擾能力強，對環(huán)境要求不高，價格低廉，可靠性高，靈活性好，開發(fā)較為容易。在我國，單片機已被廣泛應(yīng)用于工業(yè)自動化控制、自動檢測、智能儀表、家用電器等各個方面。在現(xiàn)代工業(yè)控制和一些智能化儀器儀表中，越來越多的場所需要用點陣圖形顯示器顯示漢字。漢字顯示方式是先根據(jù)所需要的漢字提取漢字點陣（如16×16點陣），將點陣文件存入ROM，形成新的漢字編碼；而在使用時則需要先根據(jù)新的漢字編碼組成語句，提取相應(yīng)的點陣進(jìn)行漢字顯示。
　　　本設(shè)計由單片機AT89C51的P0口傳送數(shù)據(jù)，P1口和P0口配合選擇所要顯示的行，P2口和P0口配合選擇所要顯示的列。再由 8×8點陣LED顯示器及其他一些外圍電路顯示所要求的顯示的點陣式漢字、圖形以及動畫。其中的漢字編碼由Zimo221應(yīng)用程序提取。
　　　關(guān)鍵詞：單片機，LED顯示器
　　　
　　　
　　　
　　　
　　　
　　　
　　　
　　　
　　　
　　　
　　　
　　　
　　　
　　
　　　　Introduction
　　　The single chip Microcomputer has been published since the 20thcentury 70's, compared to is valued people's and the attention by the extremely high natural price, therefore application very broad, the development is very quick. The single chip Microcomputer is the volume small, the weight light, the antijamming ability strong, is not high to the environment request, price inexpensive, reliability high, flexibility good, the development is easy. General engineers and technicians after study related monolithic integrated circuit knowledge, also can depend upon the single chip Microcomputer system which own strength develops hoped, and may obtain the highereconomic efficiency. Because of this, in our country, the single chip Microcomputer widely has been applied in the industrial automation control, the automatic detection, the intelligent measuring appliance, the domestic electric appliances and so on each aspect. In the modern industry control and in some intellectualized instrument measuring appliances, more and more  many  places need to use the lattice graph monitor to demonstrate the Chinese character. The Chinese character display mode is first according to the Chinese character which needs withdraws the Chinese character lattice (for example 16×16 lattice), stores the lattice document ROM, forms the new Chinese character code; But when use needs first according to the new Chinese character code composition sentence, then acts according to the new code by MCU to withdraw the corresponding lattice to carryon the Chinese character demonstration.
　　　The single chip Microcomputer controls the LED lattice demonstration at present extremely to be widespread in the public place application. For example the station starts out the time toinstruct that, the stock hall stock price display panel, the market active billboard, waits for a plane the hall to take off timetable and so on.
　　　The lattice demonstrated the characteristic is the size, the shape and the color which may defer to needs carries on the combination ,realizes each kind of language and the graph change with the monolithic integrated circuit control, achieves the advertisement spropaganda and the prompt goal.
　　　This design single chip Microcomputer AT89C51 8×8 lattice LED monitor and other some periphery electric circuit composition lattice type Chinese character, graph.
　　　Key word: The single chip Microcomputer, LED monitor
