摘要:微型計算機是大規(guī)模集成電路技術(shù)發(fā)展的產(chǎn)物，屬第四代電子計算機，它具有高性能、高速度、體積小、價格低廉、穩(wěn)定可靠、應(yīng)用廣泛的特點。就因為它的應(yīng)用非常廣泛，因此，單片機的開發(fā)應(yīng)用已成為高科技和工程領(lǐng)域的一項重大課題。而音樂現(xiàn)在也成了人們生活的一部分，生活的壓力，學(xué)習(xí)的壓力，工作的壓力，一切的不順利可以在音樂聲中放松下來，讓人們心情舒暢，聽著音樂放松心情，讓我們提高生活質(zhì)量。本論文設(shè)計一個基于單片機的簡易電子琴。電子琴是現(xiàn)代電子科技與音樂結(jié)合的產(chǎn)物，是一種鍵盤樂器。 本系統(tǒng)是以51系列單片機AT89S52為主芯片，附有矩陣鍵盤、LED顯示管、揚聲器組成。系統(tǒng)完成顯示輸入信息、播放相應(yīng)音符等基本功能。本系統(tǒng)運行穩(wěn)定，其優(yōu)點是硬件電路簡單，軟件功能完善，控制系統(tǒng)可靠，性價比較高等，具有一定的實用和參考價值。 關(guān)鍵詞：AT89S52，矩陣鍵盤，LED顯示管，揚聲器
Abstract:Microcomputers are large scale integrated circuit technology development of the fourth generation of the product, electronic computers, it has high performance, high speed, small volume, low prices, stable and reliable, widely characteristics. Just because it's very extensive, therefore, SCM for the development and application of high-tech and engineering field has become a major issue. But music now also become a part of life, life pressure, the pressure of learning, working pressure, all is not well in music can relax and let people in a relaxed mood, listen to music to relax, let us improve the quality of life. This paper is based on single chip design a simple keyboard. Modern electronic technology and keyboard is the combination of music, is a kind of keyboard instrument. SCM has strong control function and flexible programmable achieve properties, it has into modern people's life, become part of the entertainment and leisure. This system is mainly 51 series microcontroller AT89S52, accompanied by matrix keyboard, chip, speaker ，LED. System completes display input information, the basic function such as broadcast corresponding notes. This system stable operation, its advantage is hardware circuit is simple, software function consummation, the control system is reliable, cost-effective higher, has certain practical and reference value. Keywords: AT89S52, matrix, LED, speaker
