基于单片机的数字电压表设计--128435802.docVIP

摘要 单片机是一种集成电路芯片，采用超大规模技术把具有数据处理能力(如算术运算，逻辑运算、数据传送、中断处理)的微处理器(CPU)单片机可单独地完成现代工业控制所要求的智能化控制功能，这是单片机最大的特征。单片机控制系统能够取代以前利用复杂电子线路或数字电路构成的控制系统，可以软件控制来实现，并能够实现智能化现在单片机控制范畴无所不在，例如通信产品、家用电器、智能仪器仪表、过程控制和专用控制装置等等，单片机的应用领域越来越广泛。?? 关键字介绍：单片机，AT89C52，A/D转换，ADC0809，数据处理。 Abstract Chip Processor is a kind of chip of integrated circuit, adopt to exceed large-scale technology have data handling ability( such as arithmetic manipulation, logic is operational , data deliver and suspend handling) tiny processor ( CPU ). Along with Chip Processor technology develop fast, various Chip Processor come in great numbers, Chip Processor technology has become a important sign of the national modern level of science and technology. Chip Processor can complete modern industrial control alone the intelligent control function that will beg, this is the feature of biggest Chip Processor. When Chip Processor control system can replace, using the control system that complex electronic line or digital circuit forms can software control come to realize, and can realize intelligence to melt. Now, Chip Processor control category is omnipresent , for instance communicate product, electric home appliances, intelligent instrument appearance, course control and the control equipment for special purpose and so on, the application field of Chip Processor is more and more extensive. Graduate the program of design is the design of simple digital volmeter . Check on our condition for the aspects such as Chip Processor technology and programming ability mainly. Observe actual programming ability as well as the ability of independent analysis and design Chip Processor. This program solves the data handling and conversion of A/D mainly and shows the 3 modulars such as control. Control system adopts AT89C52 only flat machine, the conversion of A/D adopts ADC0809. Keyword introduction: Chip Processor, AT89C52, A/D changes, ADC0809，Data handle. 目录 第一章
