隨著計(jì)算機(jī)技術(shù)的發(fā)展，現(xiàn)代的計(jì)算機(jī)都是大規(guī)模集成電路計(jì)算機(jī)它們具有功能強(qiáng)、結(jié)構(gòu)緊湊、系統(tǒng)可靠等特點(diǎn)，其發(fā)展趨勢是巨型化、微型化、網(wǎng)絡(luò)化及智能化。微型化是計(jì)算機(jī)發(fā)展的重要方向，也就是把計(jì)算機(jī)的運(yùn)算器、控制器、存儲(chǔ)器、I/O接口四個(gè)組成部分集成在一個(gè)硅片內(nèi)，于是就出現(xiàn)了一個(gè)以大規(guī)模集成電路為主要組成的微型計(jì)算機(jī)即單片機(jī)(Single Chip Microcomputer)。正是由于單片機(jī)技術(shù)的發(fā)展，才能使LED七段數(shù)碼管能夠在減少驅(qū)動(dòng)器的情況下能夠直接被驅(qū)動(dòng)。由于LED數(shù)碼管顯示技術(shù)的優(yōu)勢使得它被廣泛應(yīng)用在工業(yè)過程控制系統(tǒng)、智能儀表，智能產(chǎn)品等領(lǐng)域。本論文重點(diǎn)介紹了LED(light emission diode)數(shù)碼管動(dòng)態(tài)顯示技術(shù)以及靜態(tài)顯示技術(shù)，并分析了各自的優(yōu)缺點(diǎn)，并且編寫了這兩種顯示技術(shù)在單片機(jī)中實(shí)現(xiàn)的關(guān)鍵編碼以及提供了參考原理簡圖。而且介紹了LED(Light
Emission Diode)數(shù)碼管的組成、顯示原理以及在電能表、電子計(jì)數(shù)器、健身車和RDY-68無線數(shù)據(jù)傳輸系統(tǒng)的應(yīng)用。

【關(guān)鍵字】：單片機(jī)，LED數(shù)碼管，動(dòng)態(tài)顯示技術(shù)，靜態(tài)顯示技術(shù)。
Abstract


Along with the technical development in calculator, the modern calculator is all a large-scale integrated circuit calculator they have the function strong, the construction tightly packed, system is been together by etc. characteristics, its development trend is a giant turning, the miniaturization, network turns and the intelligence turns.The miniaturization is an important direction that calculator develop, and also is to carries the calculator calculate the machine, controller,
saving machine, I/ O pick up a people four constitute the part gathers in a silicon slice, hence appeared a microcomputer for regarding large- scale integrated circuit as principle constituting the namely single a machine.( Single Chip Microcomputer) exactly because of single technical development in a machine, then can make LED (Light Emission Diode) seven figureses tube can under the situation of the decrease drive the machine can directly drive drive.Because the LED(Light Emission Diode figures tube shows that the technical advantage makes it applied by extensively control in the industry process the system, intelligence appearance, intelligence product etc. realm.This thesis point introduced LED(Light Emission Diode) figures tube dynamic manifestation technique and static manifestation techniques, and analyzed each from of merit and shortcoming, and the plait writes the key coding that these two kinds of manifestations technique realizes in single a machine and provides to consult principle Chien's diagram.And introduce the constitute of LED(Light Emission Diode), the manifestation principle and ameter 、electronic counter 、doing exercise to keep fit in the application on the car and RDY-68 wireless
data transmission system.

【Key word】: Single Chip Microcomputer,The figure tube ,The dynamic manifestation technique, The static manifestation technique.
