| Abstract: | Introduction was made to the features of ROC425 absolute photoelectric encoder and its Endat 2.2 bidirection digital interface.This paper raised a method based on FPGA(field programmable gate array)to read out absolute encoder value,giving out methods for hardware and software design and simulation waveform diagram.The method has achieved signals parallel reading and it has been successfully applied in a rubber dam water level test and control with better effect. |
| Keywords: | absolute photoelectric encoder FPGA chip Endat interface |
