摘 要: | 单键飞梭用户接口是嵌入式系统设计中的一种接口新方法,首先介绍了一款基于DSP+PIC32+FPGA构架的五轴植毛/钻孔数控制系统,讨论了接触式旋转编码器的特点,详细分析了接触式旋转编码器输出脉冲的抖动情况,利用旋转编码器错向输出和PIC微处理器边沿中断的特点,提出了一种新的软件消抖策略,该方法与传统的延时消抖方法相比,具有编程简单,运行可靠的特点。该方法已成功应用于五轴植毛/钻孔的面板设计中。

Abstract: | SingIe-keyed shuttIing user-interface is a new design method in embedded system.This paper introduces a numericaI controI system of five-axis hair-pIanting / driI ing hoIe machine based on DSP+PIC32+FPGA architecture,and discusses the characteristics of contact type rotary-encoder,and anaIyzes the contact jitter of rotary-encoder output puIse in detaiI.FinaI y, take fuI advantage of the characteristics of rotary-encoder's quadrature output and the edge interrupt of the PIC micropro-cessor,this paper puts forward a new soft-debounce strategy,which have some advantages such as programming simpIy and operation reIiabIy comparing with the traditionaI debounce method. |

Keywords: | rotary-encoder shuttIing input interface debounce Five-axis NC |
