I suspect the solution is available on the web if I knew the proper search terms.
My problem:
I want to drive a variable inductor with a DC motor and read it's position with a single optical encoder. The external sense circuit can stop the inductor in the middle of a pulse and reverse direction. I am seeking a pulse reading circuit that senses both direction of the pulse and time position - time is not a good word - count may be better.
i.e. say we have read 9 pulses and stop in the middle of the tenth, and then reverse direction - or worse we sort of diddle about the tenth position and get multi counts
Hope this makes some sense - I always want to do the count, the cum count and also know the direction so we and add +- as required
Thanks, Stan
