| Abstract: | A count card for optical grating ruler is designed in this paper, in which the interface chip PDIUSBD12 is adopted for USB communication, and the detection of signals from optical grating ruler is realized based on the external interrupt signals of microchip ATmega128. The measuring accuracy of displacement can reach 0.5~tm. The circuit hardware and system software process are given too This count card can be applied to automatic control, detection and other fields . |
