基于MSP430单片机实验板开发

基于MSP430单片机的实验板设计1摘要随着单片机的广泛使用，通用的单片机外围越来越被广泛的关注，设计一块通用且功能完善的单片机系统成为当今学习、研究、开发、设计的一大热门、项目。MSP430系列单片机是美国德州仪器（TI）1996年开始推向市场的一种16位超低功耗、具有精简指令集（RISC）的混合信号处理器（MixedSignalProcessor）。称之为混合信号处理器，是由于其针对实际应用需求，将多个不同功能的模拟电路、数字电路模块和微处理器集成在一个芯片上，以提供“单片机”解决方案。该系列单片机多应用于需要电池供电的便携式仪器仪表中。强大的处理能力MSP430系列单片机是一个16位的单片机，采用了精简指令集（RISC）结构，具有丰富的寻址方式（7种源操作数寻址、4种目的操作数寻址）、简洁的27条内核指令以及大量的模拟指令；大量的寄存器以及片内数据存储器都可参加多种运算；还有高效的查表处理指令；有较高的处理速度，在8MHz晶体驱动下指令周期为125ns。这些特点保证了可编制出高效率的源程序。本次实验电路包括MSP430最小系统电路、流水灯电路、数码管电路、按键电路、JTAG接口电路等的设计，实验板的布局充分考虑到了实验时的方便性，可操作性。并且还可自行设计实验内容进行实验。电路全部完成后，采用IAREmbeddedWorkbenchV5.1。通过该仿真软件来调试电路的C语言程序。关键词：MSP430、流水灯、JTAG接口电路基于MSP430单片机的实验板设计2AbstractWiththewideuseofsinglechipmicrocomputer,generalMCUperipheryhasbecomemoreandmorewidelyattention,todesignageneralandfunctionalsingle-chipmicrocomputersystembecometoday'slearning,research,development,design,abig,project.MSP430seriesSCMistheTexasinstruments(TI)beganin1996tomarketoneofthe16ultra-lowpowerconsumption,withareducedinstructionset(RISC)oftheMixedSignalProcessor(MixedSignalProcessor).Calledthemixedsignalprocessor,itisduetoitsaccordingtoactualapplicationdemand,willbeanumberofdifferentfunctionsofanalogcircuit,digitalcircuitmoduleandintegratedonasinglechipmicroprocessor,inordertoprovide\SCM\solution.Thisseriesofsingle-chipmicrocomputerappliedtoneedmorebatteriesinportableinstrumentsandmeters.PowerfulprocessingabilityofMSP430seriesMCUisa16-bitmicrocontroller,reducedinstructionset(RISC)structureisadopted,withabundantwayofaddressing(7)operandaddressing,fourdestinationoperandaddressing)andconcisearticle27kernelordersandalargeamountofsimulationinstruction;Plentyofregistersanddatastorageisavailabletoparticipateinavarietyofoperations;Andefficientlook-uptableprocessinginstructions;Havehigherprocessingspeed,andintheinstructioncycledrivenby8MHZcrystalof125ns.Thesefeaturesensurethesourceprogramcanbecompiledforhighefficiency.ThisexperimentincludeMSP430minimumsystemcircuit,waterlampcircuit,digitaltubecircuit,keycircuit,JTAGinterfacecircuitdesign,suchasthelayoutoftheexperimentalplatefullyconsideredexperimentalconvenience,operability.Anditcanalsobedesignedexperimentcontent.Circuitiscompleted,allUSEStheIAREmbeddedWorkbenchV5.1.ThroughthesimulationsoftwareofClanguageprogramtodebugcircuit.Keywords:MSP430,waterlights,JTAGinterfacecircuit基于MSP430单片机的实验板设计3目录摘要.............................................................................................................................................1Abstract.............................................................................................................................................2第1章绪论.................................................................................................................................41.1引言...................................................................................................................................41.2基于MSP430的单片机电路实验板的研究....................................................................51.2.1MSP430单片机的概念...........................................................................................51.2.2MSP430单片机的特点...........................................................................................51.2.3MSP430单片机的发展趋势...................................................................................51.3单片机电路实验板的意义.................................................................................................7第2章IAREmbeddedWorkbench仿真软件实现.........................................................................82.1IARFor430简介...............................................................................................................82.2IAREmbeddedWorkbench仿真软件介绍........................................................................82.3IAREmbeddedWorkbench仿真软件的调试.....................................................................9第3章单片机电路实验板的硬件设计.......................................................................................113.1最小系统电路的设计.......................................................................................................113.1.1电源电路的设计....................................................................................................113.1.2晶振电路的设计....................................................................................................123.1.3复位电路的设计....................................................................................................133.2六位数码管电路的设计...................................................................................................143.3JTAG电路的设计..............................................................................................................153.4流水灯电路的设计...........................................................................................................173.516位按键电路的设计......................................................................................................173.6整体硬件电路图..............................................................................................................1
