It is not a recent emergence of new technology, just as microelectronics technology and the development of puter technology, microchip control functions more and more, and control of microchips embedded in the equipment and systems more and more, making the technology more Reply People attention. Hardware and software of its size, cost, power consumption and reliability have made stringent requirements. Embedded systems function more powerful, and more and more plicated, then there is the reliability greatly reduced. A recent trend is a powerful embedded systems usually need a operating system to support the operating system is already mature and stable, can be embedded Linux, WINCE, and so on. This paper is to study under the ARM embedded system’s the system of traffic lights design and implementation. This design uses Philips39。s 32 as the LPC2138 ARM microprocessor core processors.【Keywords】Embedded Systems ARM LPC2138 traffic lights3目 錄一 設(shè)計(jì)的目的與意義 ..................................................3二 設(shè)計(jì)的內(nèi)容 ........................................................3三 設(shè)計(jì)方案 ..........................................................3 設(shè)計(jì)思路 .........................................................3 總體設(shè)計(jì)框圖 .....................................................4四 硬件設(shè)計(jì) ..........................................................4 LPC2138 芯片介紹及設(shè)計(jì) ............................................5 LPC2138 芯片最小系統(tǒng)硬件設(shè)計(jì) ......................................5 系統(tǒng)電源電路設(shè)計(jì) .................................................6 晶振與復(fù)位電路 ...................................................6 LED 循環(huán)顯示設(shè)計(jì) ..................................................7 數(shù)碼管倒計(jì)時顯示硬件設(shè)計(jì) .........................................8 蜂鳴器設(shè)計(jì) .......................................................9五 軟件設(shè)計(jì) ..........................................................9 交通燈控制軟件流程圖 .............................................9 ARM 交通燈模擬控制程序設(shè)計(jì) .......................................10六 設(shè)計(jì)心得體會及總結(jié) ...............................................11七 參考文獻(xiàn) .........................................................124一 設(shè)計(jì)的目的與意義通過設(shè)計(jì)，培養(yǎng)自己綜合運(yùn)用所學(xué)知識、獨(dú)立分析和解決實(shí)際問題的能力，培養(yǎng)創(chuàng)新意識和創(chuàng)新能力，并獲得科學(xué)研究的基礎(chǔ)訓(xùn)
