22Bits Electro-optical Matrix Encoder Adoped Sigle Chip Microcomputer

This paper introduces that MCS-51 sigle chip microcomputer is adoped for 22 bits elecfro-optical matrix encoder to perform data acquisition, interpolation, code logic transform and four correction. As a result of this treatment, complex circuit of interpolation with a chain of resistance and hard logic process for traditional encoder is replaced. The logic equation and circuit diagram of hardware interface is given and the idea of pragram design is introduced. Finally, the encoder error is discussed.
