Abstract :
In this paper, we first introduce the basic working principle of optical-electrical encoder that is a kind of digital displacement sensor. Then we present guidelines for designing optical-electrical encoder pulse counting card based on PC-bus, including such aspects as counting mode, pulse signal shaping and antijamming, data latching, I/O address allocating, read/write register format, timer and interrupt, etc. Finally we present an approach to design the driving program.
