    PSOC 3 Quadrature Decoder Component Not Counting

    user_385543602

       Hi,

         

      I have used the Quadrature Decoder (TCPWM) in PSOC 4 with no problems, but I seem to be running into trouble with PSOC 3.  It is a different component, and seemingly simpler, but I cannot get it to count at all one way or the other.  Can someone please look over the attached project and point out any software errors you see?  I want to try to eliminate software before looking into less obvious hardware issues.  I have already tested that the pins are correct, the encoder is outputting constantly, etc.

         

      Thank you,
