Abstract
[来源:http://think58.com]
The microcontroller chip designed for use AT89s52 design a digital capacitance, inductance meter, capable of measuring capacitance, inductance, and four digital display. This system consists of capacitor test chip circuits, the minimum system microcontroller 51, display parts, alarm parts, AD converter and control components. To make the system more stable, so that overall system accuracy can be protected, the data conversion circuit using the AD0809 chip, microcontroller system design using AT89S52 microcontroller as the master chip, coupled with RC power-on reset circuit and 11.0592MHZ shock circuits, display chip with TEC6122 , drive 8 digital tube display. Procedures for each implementation cycle and time-consuming shrink to a minimum, thus ensuring that the system in real time.以上是该题目的部分信息,如您需要该题目的设计或者代写毕业设计,代写毕业论文,制作单片机实物,请联系我们的客服人员:
