毕业设计（论文）-基于ARM的GPS定位信息显示器的软件设计.doc

摘要
随着计算机技术,微电子技术和网络技术的迅速发展,嵌入式系统技术是电子产品设计领域最为热门的技术之一。在消费电子、网络通信、工业控制等诸多领域得到了广泛的应用。ARM处理器是目前公认的领先的32位嵌入式RSIC微处理器,已成为许多行业嵌入式解决方案的RISC标准。ARM技术以低功耗,低成本、体积小等诸多优点在嵌入式领域获得更广泛的应用。
GPS是以卫星为基础的无线导航定位系统。它具有全能性(陆地、海洋、航空和航天)、全球性、全天候、连续性和实时性的导航、定位和定时的功能,能为用户提供精密的三维坐标、速度和时间。
本设计将阐述LPC2292的启动程序、串口UART0通讯程序、I2C通讯程序和GPS数据解码程序,重点介绍LPC2292串口UART0、I2C部件和NMEA-0813协议,在LCD显示方面介绍如何使用ZLG/GUI编写菜单界面, 本软件能正确的对GPS信息进行解码,并在液晶上显示。
关键词: LPC2292 、 GPS接收器、 I2C 、 NMEA-0813协议
Abstract
With the development of puter technology ,microelectronics work technology, embedded system is one of the most popular technology of the field of electronic product system is adopted in the fields of consumer electronics, munication, industrial control and so on. ARM processor is a kind of advance 32-bit microprocessor embedded RISC, it have ed embedded RISC stardard of solution for many industries. ARM technology have low-power, low-cost, small size and many other advantages, so it applied in the field of embedded system widely.
GPS is a Wireless navigation and positioning system based on has the function of omnipotent (terrestrial, marine, aviation and aerospace), a global, all-weather, continuity and attachment of navigation, positioning and timing,it can provide for the customer Sophisticated three-dimensional coordinates, speed and time.
This article expo und that how to program for 2292Bootloader、serial muni cation、munication .And GPS data decode,and introduce LPC 2292 emphasis on serial UART0 、I2C and NMEA-0813 protocol,and introduce how to use ZLG/GUI program menu interface in the part of lcd display. This software can decode GPS data accuracy and display on the LCD.
Keyword: LPC2292 、 GPS receiver 、 I2C 、 NMEA-0813 protocol
