Quadrature Encoder Interface PIC 2331

[enauman]

Can anyone out there tell me if swapping the a and b signals will reverse the count direction? I have a unidirectional system. It just happens to be going in the reverse direction as far as the encoder is concerned. It's a pain to deal with the poscnt registers in reverse.

Thanks,

Ed

Hi,
Yes it will change count direction.

Thanks. It worked.
