毕业论文论文题目：USB设备的从动端分析与应用设计——固件程序设计学院：计算机科学技术学院摘要USB（UniversalSerialBus通用串行总线)是计算机领域中一种全新的工业标准，其技术和产品正在迅猛的发展中。因此，研究USB总线的体系架构和开发技术很有必要。本文在实验室现有硬件和软件基础上，研究了USB的接口规范和软硬件开发方法，并应用于实际，设计出了用USB实现的温度采集系统。本文围绕设计目标，在简要叙述USB1.1总线协议的基础上，主要论述了两个方面的内容:固件程序的开发和DS1620的使用方法。设备以AT89S52单片机作为控制器，Philips公司的PDIUSBD12作USB收发器，用DALLAS公司的DS1620进行温度采集，采用中断数据传输方式实现数据传输。关键词USB；WDM；PDIUSBD12；温度采集；DS1620ABSTRACTUSB（UniversalSerialBus)isacompletelynewindustrystandardinthefieldofcomputer.Itstechnologyandproductaretremendouslydeveloping.Therefore,ItisnecessarytoresearchtheframeanddevelopingtechnologyofUSB.Basedonthehardwareandsoftwarethatourlaboratoryishaving,thispaperresearchestheinterfacestandardandsoftware-hardwaredevelopingmethodsofUSB,applyitintotheactualenvironment,anddesignedthetemperaturecollectionsystem.Centeringonthedesigningobject,outliningtheUSB1.1protocol,thispapermainlyexpoundtwoaspectsofcontent:thedevelopingoffirmwareprogramandemploymentofDS1620.UsingAT89S52ascontrolappliance,PDIUSBD12ofPhilipsCorp.asUSBreceiving-transmittingappliance,thedevicecollecttemperaturewithDS1620ofDALLASCorp.,andadoptinterruptdatatransmittingtorealizedatatransition.KeywordsUSB；WDM；PDIUSBD12；temperaturecollection；DS1620USB设备的从动端分析与应用设计—固件程序设计目录摘要.................................................................................................................................................................iABSTRACT.........................................................................................................................................................ii前言..................................................................................................................................................................1一、本文研究的主要内容..........................................................................................................................1二、USB发展情况......................................................................................................................................1三、USB的设计目标..................................................................................................................................2四、USB的性能特点..................................................................................................................................2四、USB系统组成......................................................................................................................................3（一）USB的互连..................................................................................................................................3（二）USB设备......................................................................................................................................4（三）USB主机......................................................................................................................................5第一章USB数据传输协议.......................................................................................................................
