摘要
根据增量式光电码盘进行位置检测的原理,本文提出了一种基于CPLD的器件的实现增量式光电码盘的设计方案。简略介绍了EMP7128器件的主要特点,详细分析了四倍频计数电路和接口电路的设计原理。
Based on the theory of incremental type of photoelectrical encoder position detection,this paper puts forth a design method of incremental type of photoelectrical encoder. The main characters of EMP7128 were briefly introduced, and design principle of fourfold frequency and interface circuits were analyzed in detail.
