Design of ARM-based Graphic Instrument for Numerical Control Algorithm

A graphic instrument is designed for the digital control study especially the various digital interpolation algorithms and its performance and the status.This graphic instrument can capture the pulse-level signals of the control chip in real-time,then the signal and relationship among interpolation algorithm,pulse and trajectory thought of a group of pulse sequence zoomed by proportion and a coordinates map are analysed.It has advantages of simple structure,practical function and low price.
