Swapping A & B will reverse the direction, but that is it. Is it bad on all
axis? What is the environment you are testing in? is it possible you are
getting noise on the line? Do your encoders have built in pull-ups or do you
have to add some? Lots of the nicer encoders are open collector and need
pull-ups.
