【正文】 logy is used with data processing capabilities to the central processing unit CPU random access memory RAM, readonly memory ROM, a variety of I / O port and interrupt system, timers / timer Other functions (and possibly the display driver circuit, pulse width modulation circuit, analog multiplexers, A / D converter circuit) into a single silicon wafer consisting of a small but plete puter system. At89S52 is a low power, high performance CMOS8 bit microcontroller with 8K insystem programmable Flash memory. Using Atmel39。 D base, top accessories from more than 70 vendors to participate in the development of a new product Apple process. The world39。 D capabilities and innovation outside the pany make better use of peripheral resources is also an important part of its success. Apple39。s first CD player, but also the production of the first Sony CD player, bornSony 39。 the other is loved by everyone, for the popularity of portable electronic keyboard music education. Both the keyboard can be inherent in the issue of their own sound but also can mimic a number of other instruments and sounds of nature. They e with automatic tempo and acpaniment function, which is it different from other important characteristics of a keyboard instrument. Portable Keyboard and the vertical keyboard in teaching methods are very similar, but the materials used on the slightly different: the vertical keyboard organ from their ancestors get rich training system, and ability to play portable keyboard used in the training of many The contents of piano practice.Right now, the music player has bee an integral part of people39。s. The mon key keyboard is a single row of 6039。四、主要參考文獻(xiàn)（不少于10篇，期刊類文獻(xiàn)不少于7篇，應(yīng)有一定數(shù)量的外文文獻(xiàn)，至少附一篇引用的外文文獻(xiàn)（3個(gè)頁(yè)面以上）及其譯文）[1]黃振杰， 單片機(jī)的多功能音樂(lè)播放器[J].電子設(shè)計(jì)工程，2009，（02）.[2]張紅梅，[J]. 電子質(zhì)量，2008，（05）.[3][J].電子制作，2007，（03）.[4]汪本慧. 基于單片機(jī)的多功能音樂(lè)播放器的設(shè)計(jì)與制作[J].電腦學(xué)習(xí)， 2010，（05）.[5][J].電子世界，2005，（07）.[6]舒紅波,李蔚,[J].控制工程，2004，（07）.[7][J].電子元器件應(yīng)用， 2010（12）.[8]Adam Vaughan.

Hammond, 1930 American inventor of practical significance launched electromechanical organ, called the Hammond piano. Electromagnetic coil around it by over 91 issued a munication angle sound waves round, finishing as the sine wave synthesis sound. It has two 61 key keyboard and a set of handfoot 32key keyboard, can simulate the 20 kinds of sounds, this piano application for patent in 1934, began mass production in 1935. Sales in 1937 to only 3,000 units. However, because the sound principle of Hammond for the mechanical and electrical piano, it can only be described as the first TPC organ. But its shape and structure of the double bond later became the prototype of the keyboard.Overall, the keyboard of the invention is from 3039?！? 第十七周 形成畢業(yè)設(shè)計(jì)全部文件，準(zhǔn)備答辯。 第十六周 設(shè)計(jì)的仿真。 第十四周 檢查總體方案確保無(wú)誤?！? 第十二周 彩燈模
