一种编码器实时读出电路设计及处理方法

设计一个编码器实时读出系统。采用FPGA作为处理器对增量式编码器和绝对值编码器进行读值,然后将从编码器读入的数据信息转化为角度值,最后驱动液晶显示模块进行实时读出角度值。硬件部分主要包括一块FPGA控制器、两种编码器接入模块、一个LCD模块,以及外围配置电路。软件部分主要包括编码器数字信号接收、数据处理、LCD驱动显示。电路板可用于检验实验室采购的编码器,保障生产任务按时完成;也可以置于各种平台之上,用于实时显示方位角度值。

A real-time encoder readout circuit design and processing method

Designing a real time encoder readout system.It uses the FPGA as a processor,which reads data from the incremental style encoder and the absolute value encoder,then transforms the data information into angle value,and drives the LCD to display the angle value in real time.The hardware largely includes a FPGA,two encoder access module,a LCD module and peripheral circuit configurations.The software includes an encoder digital signal read,data processing and LCD display driver.the circuit board can be used to test encoders procuremented by our laboratory,of course,it can also be used on a variety of platforms to diaplay angle value in real time.
