摘要
笔者开发的DDMM8850型数字多用表,基于单片机技术,具有成本低、性能高的优点,完全可替代同类型的进口5-1/2位数字多用表。该数字表已完成了设计和调试,并试制出了样机。文中主要探讨其核心硬件电路的设计和开发。
The Author designs and empolders the digital multimeter DDMM8850,it is based on Single Chip Micyoco technology and has the advantages of low cost and high performace.it can also substitute the imported Digital multimeter 5-1/2 completely.We have accomplished the design debugging of it and made a model machine.This article mainly discusses the design exploitation of the kerna hardware circuit.
