摘　　要：编码器位置检测通道的扩展是机器人或多轴设备运动控制系统中经常碰到的问题,由于微控制器的正交解码脉冲接口电路有限,需要另外设计硬件电路扩展。介绍正交解码器HCTL-2032的工作原理,设计了与TMS320F2812的接口电路,并给出了读取数据的流程。HCTL-2032内部集成了滤波、正交解码、计数等功能,与CPU接口方便,可提高系统的稳定性和可靠性,非常适用于多轴运动控制系统的开发。The expanding encoder position detection channels is often encountered in the motion control system of robot or multi-axis.Because of the limit interface of MCU quadrature decoder,it needs to expand the other circuit.The operation principle of quadrature decoder IC HCTL-2032 is given.The interface circuit between TMS320F2812 and encoder and the flow of reading data are introduced.The quadrature decoder IC includes filter, quadrature decoder,counter and so on.So HCTL-2032 is very cmpatiable to interfaces with CPU and can improve the system＇s stability and dependablity. The quadrature decoder IC be suited for multi-axis control system.
