Quadrature decoder
Been searching all morning for one, and did find one by LSI/ LS7184. I have been looking at a drawing of one from the mid 70's, drawn up by a coworker who is long gone. using 74121;'s and 7400. I got a sample request, but I think i can do this myself quickly. I got stepper motors and controllers requiring ste... 3 Jun 2010 05:40
