Abstract

Instead of the traditional design of digital display devices,this paper adopts an design constituted by CPLD and microcontroller. EPM240 CPLD chips are used to manipulate output signal, and the microcontroller reads the data get what the EPM240 CPLD chips display. Full text gives the simulation results by this design, shows the real product and compares with the relevant experiments. All the experiments show that the design processes abilities of data processing and real-time display with high accuracy of measurement and stability.This design can be used for the actual measurement and output system of grating displacement.
