【正文】 s of renovated function. It is also present in many household appliances feature a large number of additional factors. 2 single chip puter with you to the industrial area The 21st century is the century of humanity into the puter age, many people are not used in the manufacture of puter is the puter. People using the puter, only the people engaged in embedded system applications really into the internal puter system hardware and software systems, can we truly understand the nature of the puter39。 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 development. This 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.SCM will create a new generation of electronic elite If the 5039。參考文獻(xiàn)[1]：人民郵電出版社,2006.[2]：浙江大學(xué)學(xué)報(bào)，1998.[3]：西安電子科技大學(xué)出版社，2004.[4]：北京航空大學(xué)出版社，.[5]王兆安、:機(jī)械工業(yè)出版社,2000.[6]李全力，：高等教育出版社，.[7]：哈工大出版社，.[9]（第二版）：.[10]DALLAS SEMICOND UCTOR,DS2438 SmartBattery Monitor.[11]周志敏、:.[12]潘新民、:.[13]李池水,龔華志,:2533.[14]鄭人杰. 計(jì)算機(jī)軟件測(cè)試技術(shù). 北京:清華大學(xué)出版社, 1992.[15][碩士學(xué)位論文].浙江大學(xué),浙江2004年.外文文獻(xiàn)From the world of radio in the world to a single chipModern puter technology, industrial revolution, the world economy from the capital into the economy to knowledge economy. Field in the electronic world, from the 20th century into the era of radio to puter technology in the 21st century as the center of the intelligent modern era of electronic systems. The basic core of modern electronic systems are embedded puter systems (referred to as embedded systems), while the microcontroller is the most typical and most extensive and most popular embedded systems.Single chip to create the modern era of electronic systems 1 A microcontroller and embedded systemsEmbedded puter systems from embedded applications, embedded systems for early generalpurpose puter adapted to the object system embedded in a variety of electronic systems, such as the ship39。 同時(shí)，在論文寫(xiě)作過(guò)程中，我還參考了有關(guān)的書(shū)籍和論文，在這里一并向有關(guān)的作者表示謝意。在此向曲紹華老師表示深深的感謝和崇高的敬意！ 在臨近畢業(yè)之際，我還要借此機(jī)會(huì)向在這四年中給予我諸多教誨和幫助的各位老師表示由衷的謝意，感謝他們四年來(lái)的辛勤栽培。謝 辭 本論文設(shè)計(jì)在曲紹華老師的悉心指導(dǎo)和嚴(yán)格要求下業(yè)已完成，從課題選擇到具體的寫(xiě)作過(guò)程，論文初稿與定稿無(wú)不凝聚著曲紹華老師的心血和汗水，在我的畢業(yè)設(shè)計(jì)期間，曲紹華老師為我提供了很多專(zhuān)業(yè)知識(shí)上的指導(dǎo)和一些富于創(chuàng)造性的建議。我們基本完成了預(yù)期的任務(wù),當(dāng)然還有很多東西需要繼續(xù)學(xué)習(xí)。在設(shè)計(jì)中，我們力求硬件電路簡(jiǎn)單，充分發(fā)揮軟件靈活方面的特點(diǎn)，滿(mǎn)足系統(tǒng)設(shè)計(jì)要求。當(dāng)按下出門(mén)按鈕時(shí)，繼電器動(dòng)作將門(mén)鎖打開(kāi)指示燈點(diǎn)亮，延時(shí)一段時(shí)間后繼電器再次動(dòng)作將門(mén)鎖鎖閉指示燈熄滅。顯示 SETB ； CLR LCALL DEL CLR ； MOV R5,40H；將40H地址的值給R5 L8: LCALL DEL DJNZ R5,L8；判斷R5和L8地址中的值 SETB CLR JNB ； LJMP M1；轉(zhuǎn)移到M1 AL: CLR LCALL DEL SETB ； RET SIC: ANL TMOD,0FH ORL TMOD,20H MOV TH1,0FDH；將0FDH值給TH1 MOV TL1,0FDH SETB TR1 MOV IE,90H MOV SCON,50H RET ZD: PUSH ACC PUSH 00H；00H值加1 PUSH 02H MOV R0,30H將30H值給R0 MOV R2,0BH LL1: ACALL LL2 JB F0,LL3；判斷F0和LL3的值 NOP NOP MOV R0,A INC R0；將R0中的值加1 DJNZ R2,LL1 POP 02H POP 00H POP ACC NOP MOV 0FH,33H RET LL2: MOV 04H,28H LL4: JNB RI,LL6 CLR RI；清除R1中的值 MOV A,SBUF CLR F0 RET LL6: MOV 05H,0AH；將0AH的值給05H LL5: DJNZ R5,LL5 DJNZ R4,LL4 SETB F0 RET LL3: POP 02H POP 00H POP ACC RETI L04E0:MOV R0,30H MOV R2,0AH L04E4:MOV A,R0；將R0地址的值給A ACALL L04A0 MOV R0,A INC R0；將R0值減1 DJNZ R2,L04E4 RET L04A0:CJNE A,40H,L13 SJMP L04AD L13:JC L04A9 ADD A,09H；將09H的值加1給A L04A9:ANL A,0FH CLR C RET L04AD:SETB C；將后面的值為0 RET L04B0:MOV A,30H SWAP A ADD A,31H MOV 30H,A；將A的值給30H MOV A,32H SWAP A；選擇A中的值 ADD A,33H MOV 31H,A NOP NOP MOV A,34H SWAP A將A中高四位和第四位交換 ADD A,35H；把35H的值加1給A MOV 32H,A MOV A,36H SWAP A ADD A,37H MOV 33H,A NOP ；刪除是否對(duì)程序有影響 NOP MOV A,38H SWAP A SWAP A ADD A,39H MOV 34H,A RET L1234：MOV 35H,33H MOV R0,34H MOV R7,02H MOV R1,28H LCALL LOD91 RET LOD91:MOV A,R0
