I have a 6-segment rotary switch with each of the wheels having digits 0-9. Each segment has a common pin and 4 data pins for the different digit combinations.
I've written some code that can run a 74165 shift register and 74138 decoder, but I'm having some difficulty figuring out how to build the supporting circuitry that will allow me to sequentially go from segment to segment so that i only need one shift register IC. I admit my knowledge of electronics hasn't yet caught up with my programming ability and I'm at a loss right now figuring out how to do it.
There seem to be several posts about how to use an individual rotary switch, but i haven't found one yet that uses multiple. Any suggestions?
