【正文】 rent. The former requires massive data storage, handling, processing and analysis of highspeed data transmission。 air conditioner after use of SCM is not only convenient for remote parameter setting, running automatically transform, frequency control can be achieved. At present, many household appliances such as VCD, DVD only single chip to achieve its function may occur before. 3 Embedded Systems led the entire electronics industry Current electronic ponents industry, in addition to microprocessors, embedded system devices, the most modern electronic systems around the supporting ponents industries, such as keys used to meet the humanputer interaction, LED / LCD display drivers, LED / LCD display units, voice integrated device, etc., to meet the requirements of data acquisition channel digital sensor, ADC, data acquisition module, signal conditioning modules to meet the servo drive control in the DAC, solid state relays, stepper motor controller, frequency control unit, etc., to meet the munication requirements various bus driver, level converters. Electronic ponents in the embedded systems world, driven by embedded applications along fully meet requirements of modern electronic systems makes the original classic world of increasingly small electronic systems. Practitioners in the various electronic systems to modern electronic systems as early as possible to stay. 5, SCM will create a new generation of electronic elite If the 5039。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(wú)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(shí)經(jīng)濟(jì)時(shí)代 .在電子世界領(lǐng)域 ,從 20 世紀(jì)中的無(wú)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(jiǎn)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(wú)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(wú)線電技術(shù) ,包括無(wú)線電廣播 ,收音 ,無(wú)線通信 (電報(bào) ),業(yè)余無(wú)線電臺(tái) ,無(wú)線電定位 ,導(dǎo)航等遙測(cè) ,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(wú)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(wú)線電電子學(xué) ,無(wú)線通信開始了電子世界的歷程 . 無(wú)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(wú)窮的樂(lè)趣 .從床頭的礦石收音機(jī)到超外差收音機(jī) ?？照{(diào)機(jī)采用單片機(jī)后不但遙控參數(shù)設(shè)置方便 , 運(yùn)行狀態(tài)自動(dòng)變換 ,還可實(shí)現(xiàn)變頻控制 .目前許多家用電器如 VCD,DVD 只有單片機(jī)出現(xiàn)后才可能實(shí)現(xiàn)其功能 . 3 嵌入式系統(tǒng)帶動(dòng)了整個(gè)電子產(chǎn)業(yè) 目前電子元器件產(chǎn)業(yè)除了微處理器 ,嵌入式系統(tǒng)器件外 ,大多是圍繞現(xiàn)代電子系統(tǒng)配套的元器件產(chǎn)業(yè) ,例如滿足人機(jī)交互用的按鍵 ,LED/LCD 顯示驅(qū)動(dòng) ,LED/LCD 顯示單元 ,語(yǔ)音集成器件等 ,滿足數(shù)據(jù)采集通道要求的數(shù)字傳感器 ,ADC,數(shù)據(jù)采集模塊 ,信號(hào)調(diào)理模塊等 ,滿足伺服驅(qū)動(dòng)控 制的 DAC,固體繼電器 ,步進(jìn)電機(jī)控制器 ,變頻控制單元等 ,滿足通信要求的各種總線驅(qū)動(dòng)器 ,電平轉(zhuǎn)換器等 . 世界電子元器件在嵌入式系統(tǒng)帶動(dòng)下 ,沿著充分滿足嵌入式應(yīng)用的現(xiàn)代電子系統(tǒng)要求發(fā)展 .這就使原來(lái)經(jīng)典電子系統(tǒng)的天地愈來(lái)愈小 .電子系統(tǒng)中的各類從業(yè)人員應(yīng)盡早轉(zhuǎn)向現(xiàn)代電子系統(tǒng)的康莊大道 . 五 , 單片機(jī)將造就新一代電子精英 如果說(shuō)五十年代起 ,無(wú)線電世界造就了幾代精英 ,那么當(dāng)今的單片機(jī)世界將會(huì)造就出新一代電子精英 . 1 單片機(jī)帶你進(jìn)入智能化電子領(lǐng)域 若將經(jīng)典電子系統(tǒng)當(dāng)作一個(gè)僵死的電子系統(tǒng) ,那么智能化的現(xiàn)代電子 系統(tǒng)則是一個(gè)具有生命 的電子系統(tǒng) .單片機(jī)應(yīng)用系統(tǒng)
