38、进制码，对于一般的红外遥控系统，此串行码输入到微掌握器，由其内部 CPU完成对遥控指令解码，并执行相应的遥控功能；使用遥控器作为掌握系统的输入，需要解决如下几个关键问题：如何接收红外遥控信号；如何识别红外遥控信号以及解码电路的设计、掌握程序的设 计；在本片文章中我们主要介绍单片机以及主选芯片的介绍；单片机芯片单片机产生于 1971 年，经受了 SCM、MCU、SOC三大阶段；它由运算器 , 掌握器, 储备器, 输入输出设备构成；它的全称是单片微型电脑，是典型的嵌入式微掌握器 Microcontroller Unit，常用英文字母的缩写 MCU表示单片机，它最早是被用在工业掌握领域；由于单片机在

39、工业掌握领域的广泛应用，为使 更多的业内人士、同学、爱好者，产品开发人员把握单片机这门技术，于是产 生单片机开发板，比较出名的例如电子人DZR-01A单片机开发板；单片机由芯片内有 CPU的专用处理器进展而来；最早的设计理念是通过将大量外围设备和CPU集成在一个芯片中，使电脑系统更小，更简洁集成进复杂的而对体积要求 严格的掌握设备当中；同时单片机又称单片微掌握器，它不是完成某一个规律 功能的芯片，而是把一个电脑系统集成到一个芯片上；相当于一个微型的电脑，和电脑相比，单片机只缺少了I/O 设备；单片机是靠程序运行的，并且可以修改；通过不同的程序实现不同的功能，特别是特别的特殊的一些功能，这 是别

40、的器件需要费很大力气才能做到的，有些就是花大力气也很难做到的；一 个不是很复杂的功能要是用美国50 岁月开发的 74 系列，或者 60 岁月的CD4000系列这些纯硬件来搞定的话，电路肯定是一块大PCB板！但是假如要是用美国 70 岁月胜利投放市场的系列单片机，结果就会有天壤之别！只由于单片机的通过你编写的程序可以实现高智能，高效率，以及高牢靠性！由于单片机对成本是敏锐的，所以目前占统治位置的软件仍是最低级汇编语言，它是除了二进制机器码以上最低级的语言了，既然这么低级为什么仍要用呢？许多高级的语言已经到达了可视化编程的水平为什么不用呢？缘由很简单，就是单片机没有家用电脑那样的CPU，也没有像硬

41、盘那样的海量储备设备；一个可视化高级语言编写的小程序里面即使只有一个按钮，也会到达几十K的尺寸！对于家用 PC的硬盘来讲没什么，可是对于单片机来讲是不能接受的； 单片机在硬件资源方面的利用率必需很高才行，所以汇编虽然原始却仍是在大量使用；一样的道理，假如把巨型电脑上的操作系统和应用软件拿到家用PC上来运行，家用 PC的也是承担不了的；可以说，二十世纪跨过了三个“电”的时代，即电气时代、电子时代和现已进入的电脑时代；不过，这种电脑，通常是指个人电脑，简称PC机；它由主机、键盘、显示器等组成；仍有一类电脑，大多数人却不怎么熟识；这种电脑就是把智能给予各种机械的单片机亦称微掌握器；顾名思义，这种电脑

42、的最小系统只用了一片集成电路，即可进行简洁运算和掌握；由于它体积小，通常都藏在被控机械的“肚子”里；它在整个装置中，起着有如人类头脑的作 用，它出了毛病，整个装置就瘫痪了；现在，这种单片机的使用领域已特别广泛，如智能外表、实时工控、通讯设备、导航系统、家用电器等；各种产品一旦用上了单片机，就能起到使产品升级换代的成效，常在产品名称前冠以形容词“智能型”，如智能型洗衣机等；现在有些工厂的技术人员或其它业余电子开发者搞出来的某些产品，不是电路太复杂，就是功能太简洁且极易被仿制；究其缘由，可能就卡在产品未使用单片机或其它可编程规律器件上；单片机的应用领域目前单片机渗透到我们生活的各个领域，几乎很难找

43、到哪个领域没有单片机的踪迹；导弹的导航装置，飞机上各种外表的掌握，电脑的网络通讯与数据传输，工业自动化过程的实时掌握和数据处理，广泛使用的各种智能IC 卡，民用豪华轿车的安全保证系统，录像机、摄像机、全自动洗衣机的掌握，以及程控玩具、电子宠物等等，这些都离不开单片机；更不用说自动掌握领域的机器人、智能外表、医疗器械了；因此，单片机的学习、开发与应用将造就一批电脑应用与智能化掌握的科学家、工程师；单片机广泛应用于仪器外表、家用电器、医用设备、航空航天、专用设备的智能化治理及过程掌握等领域，大致可分如下几个范畴：智能仪器外表上的应用单片机具有体积小、功耗低、掌握功能强、扩展敏捷、微型化和使用便利等

44、优点，广泛应用于仪器外表中，结合不同类型的传感器，可实现诸如电压、功率、频率、湿度、温度、流量、速度、厚度、角度、长度、硬度、元素、压力等物理量的测量；采纳单片机掌握使得仪器外表数字化、智能化、微型化， 且功能比起采纳电子或数字电路更加强大；例如精密的测量设备功率计，示波器，各种分析仪；2. 在工业掌握中的应用用单片机可以构成形式多样的掌握系统、数据采集系统；例如工厂流水线的智能化管3. 在家用电器中的应用可以这样说，现在的家用电器基本上都采纳了单片机掌握，从电饭褒、洗衣机、电冰箱、空调机、彩电、其他音响视频器材、再到电子秤量设备，五花八门，无所不在；4. 在电脑网络和通信领域中的应用现代的单

45、片机普遍具备通信接口，可以很便利地与电脑进行数据通信，为 在电脑网络和通信设备间的应用供应了极好的物质条件，现在的通信设备基本 上都实现了单片机灵能掌握，从，机、小型程控交换机、楼宇自动通信呼叫系统、列车无线通信、再到日常工作中随处可见的移动，集群移动通信，无线电对讲机等；5. 单片机在医用设备领域中的应用单片机在医用设备中的用途亦相当广泛，例如医用呼吸机，各种分析仪， 监护仪，超声诊断设备及病床呼叫系统等等；6. 在各种大型电器中的模块化应用某些专用单片机设计用于实现特定功能，从而在各种电路中进行模块化应用，而不要求使用人员明白其内部结构；如音乐集成单片机，看似简洁的功 能，微缩在纯电子芯片

46、中有别于磁带机的原理，就需要复杂的类似于电脑的原理；如：音乐信号以数字的形式存于储备器中类似于ROM，由微掌握器读出，转化为模拟音乐电信号类似于声卡；在大型电路中，这种模块化应用极大地缩小了体积，简化了电路，降低了损坏、错误率，也便利于更换；7. 单片机在汽车设备领域中的应用单片机在汽车电子中的应用特别广泛，例如汽车中的发动机掌握器，基于 CAN总线的汽车发动机灵能电子掌握器， GPS导航系统， abs 防抱死系统，制动系统等等；此外，单片机在工商，金融，科研、训练，国防航空航天等领域都有着特别广泛的用途，所以单片机的进展前景特别客观；概括的讲：单片机的体积小、质量轻、价格廉价、为学习、应用和

47、开发供应了便利条件；同时，学习使用单片机是明白电脑原理与结构的最正确挑选；单片机是人们学习和应用相关技术的最正确挑选；主控芯片 AT89S51AT89S51 是美国 ATMEL 公司生产的低功耗，高性能 CMOS8 位单片机， 片内含 4k bytes的可系统编程的 Flash只读程序储备器 ,器件采纳 ATMEL 公司的高密度、非易失性储备技术生产，兼容标准8051 指令系统及引脚；它集Flash 程序储备器既可在线编程 ISP也可用传统方法进行编程及通用8 位微处理器于单片芯片中；功能概述：AT89S51 供应以下标准功能： 4k 字节 Flash闪速储备器， 128 字节内部RAM， 32 个 I O 口线，看门狗 WDT ，两个数据指针，两个 16 位定时计数器，一个 5 向量两级中断结构，一个全双工串行通信口，片内振荡器准时钟电路；同时， AT89S51可降至 0Hz 的静态规律操作，并支持两种软件可选的节电工作模式；闲暇方式停止 CPU的工作，但答应 RAM，定时计数器，串行通信口及中断系统连续工作；掉电方式储存RAM中的内容，但振荡器停止工作并禁止其它全部部件工作直到下一个硬件复位；
