什么是单片机
单片机又称单片微控制器,它不是完成某一个逻辑功能的芯片,而是把一个计算机系统集成到一个芯片上。概括的讲:一块芯片就成了一台计算机。它的体积小、质量轻、价格便宜、为学习、应用和开发提供了便利条件。同时,学习使用单片机是了解计算机原理与结构的最佳选择。
可以说,二十世纪跨越了三个“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,通常是指个人计算机,简称PC机。它由主机、键盘、显示器等组成(如图1所示)。还有一类计算机,大多数人却不怎么熟悉。这种计算机就是把智能赋予各种机械的单片机(亦称微控制器)。顾名思义,这种计算机的最小系统只用了一片集成电路,即可进行简单运算和控制。因为它体积小,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十分广泛,如智能仪表、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功效,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,就是功能太简单且极易被仿制。究其原因,可能就卡在产品未使用单片机或其它可编程逻辑器件上。
单片机的应用领域 :
1.单片机在智能仪器仪表中的应用;
2.单片机在工业测控中的应用;
3.单片机在计算机网络和通讯技术中的应用;
4.单片机在日常生活及家电中的应用;
5.单片机在办公自动化方面。
目前单片机渗透到我们生活的各个领域,几乎很难找到哪个领域没有单片机的踪迹。导弹的导航装置,飞机上各种仪表的控制,计算机的网络通讯与数据传输,工业自动化过程的实时控制和数据处理,广泛使用的各种智能IC卡,民用豪华轿车的安全保障系统,录象机、摄象机、全自动洗衣机的控制,以及程控玩具、电子宠物等等,这些都离不开单片机。更不用说自动控制领域的机器人、智能仪表、医疗器械了。因此,单片机的学习、开发与应用将造就一批计算机应用与智能化控制的科学家、工程师。
