【正文】 o meet the growing demands of its control functions and peripheral interface functions, in particular, highlight the control function, so has international name the single chip microcontroller (MCU, Microcontroller Unit). 2 MCU modern electronic systems consisting of electronic systems will bee mainstream MCU is a devicelevel puter systems, it can be embedded into any object system to achieve intelligent control. Small to micromachinery, such as watches, hearing aids. Lowcost integrated devicelevel, lowto a few dollars, ten dollars, enough to spread to many civilian SCM appliances, electronic toys to go. SCM constitutes a modern electronic systems has indepth to the households, are changing our lives, such as home audio, televisions, washing machines, microwave ovens, telephones, security systems, and air conditioners. SCM innovation the original electronic systems, such as microwave ovens use SCM, it can easily set the clock, the program memory, power control。s puter software training, hardware and technical personnel of one of the best roads. 3 SCM bring you into the most attractive in the digital world Charming single chip to enable you to experience the true meaning of the puter, you can design intelligent microcontroller handson toys, different applications can be designed to achieve different functions. Both software design and hardware making there, both mental and physical, but also hands. Primary level can develop intelligent toys, with macro programming. Intermediate levels can develop some intelligent controller, such as puter mouse, smart cars, all kinds of remote control model. High levels can be developed robots, such as robot soccer, the development of industrial control units, work munications, and highlevel language with assembly language or design application. Microcontroller and embedded systems around the formation of the future of the electronics industry, will provide a vast world of electronic fans, an even broader than the current wireless world, richer, more durable, more attractive in the digital world. Plunge into the microcontroller in the world to, will benefit your life. 從無線電世界到單片機(jī)世界 現(xiàn)代計(jì)算機(jī)技術(shù)的產(chǎn)業(yè)革命 ,將世界經(jīng)濟(jì)從資本經(jīng)濟(jì)帶入到知識經(jīng)濟(jì)時(shí)代 .在電子世界領(lǐng)域 ,從 20 世紀(jì)中的無線電時(shí)代也進(jìn)入到 21 世紀(jì)以計(jì)算機(jī)技術(shù)為中心的智能化現(xiàn)代電子系統(tǒng)時(shí)代 .現(xiàn)代電子系統(tǒng)的基本核心是嵌入式計(jì)算機(jī)系統(tǒng) (簡稱嵌入式系統(tǒng) ),而單片機(jī)是最典型 ,最廣泛 ,最普及的嵌入式系統(tǒng) . 一 , 無線電世界造就了幾代英才 在 20 世紀(jì)五六十年代 ,最具代表的先進(jìn)的電子技術(shù)就是無線電技術(shù) ,包括無線電廣播 ,收音 ,無線通信 (電報(bào) ),業(yè)余無線電臺 ,無線電定位 ,導(dǎo)航等遙測 ,遙控 ,遙信技術(shù) .早期就是這些電子技術(shù) 帶領(lǐng)著許多青少年步入了奇妙的電子世界 ,無線電技術(shù)展示了當(dāng)時(shí)科技生活美妙的前景 .電子 科學(xué)開始形成了一門新興學(xué)科 .無線電電子學(xué) ,無線通信開始了電子世界的歷程 . 無線電技術(shù)不僅成為了當(dāng)時(shí)先進(jìn)科學(xué)技術(shù)的代表 ,而且從普及到專業(yè)的科學(xué)領(lǐng)域 ,吸引了廣大青少年 ,并使他們從中找到了無窮的樂趣 .從床頭的礦石收音機(jī)到超外差收音機(jī) 。s basic system on a chip, the formation of the early SCM (Single Chip Microputer). After the advent of single chip in the puter industry began to appear in the generalpurpose puter systems and embedded systems the two branches. Since then, both the embedded system, or generalpurpose puter systems have been developed rapidly. Although the early generalpurpose puter converted the embedded puter systems, and real embedded system began in the emergence of SCM. Because the microcontroller is designed specifically for embedded applications, the MCU can only achieve embedded applications. MCU embedded applications that best meet environmental requirements, for example, chiplevel physical space, largescale integrated circuits lowcost, good peripheral interface bus and outstanding control of instruction. A puter system microcontroller core, embedded electronic systems, intelligent electronic systems for the foundation. Therefore, the current single chip electronic system in widespread use of electronic systems to enable rapid transition
