Hi!
I am currently working on an assignment using 4 thumbwheels to control 4 7 Segments. However, to reduce the number of I/O pins used, i will have to multiplex the 7 segments(Common Cathode).

I am unsure of the codes to used to control each segment. Anyone have any guidelines for me?

Currently using C only.

Thanks
