Design and Implementation of Keyboard Module in V-Groove CNC System Based on LPC1343

Abstract:

The V-groove component which needs to be machined by ultra-precision CNC (Computer numerical control) machine tool is a core part in optical fiber connector. A design of keyboard module for V-groove ultra-precision CNC system based on LPC1343 is presented. This paper introduced the functions and features of LPC1343 and described the overall hardware structure of the keyboard module at first. Then the basic design, such as scan and decoding, design principle of module circuit and communication process between keyboard module and upper computer, were emphasized in detail. Afterwards, the functional design including data editing, LED indicator driving, override switch adjusting and motion control operating were also finished. A series of test have been conducted and the results have shown that this kind of keyboard module is reliable and stable.
