使用CPLD桥接旋转编码器和数字电位器

The Bridging Method of Rotary Encoder and Digital Potentiometer by CPLD

介绍旋转编码器和数字电位器的功能和接口,阐述了使用CPLD来桥接两者的方法,并对使用VHDL语言的程序进行了软件仿真和实际测试。

In this paper, the features and interfaces of Rotary Encoder and Digital Potentiometer bridged by CPLD were briefly introduced. The bridging method was described and the VHDL program for CPLD was performed by software simulation and hardware test.
