PIC / Seven Segment .......

hello people,

I am trying to make a score board with 18 Seven Segments. I am planning to use a PIC microcontroller.

But I have no idea how I am gonna connect all Segments and switches to one or two PICs.

I would really appreciate if anyone of you likes to share how to connect them.

thank you very much indeed

u need 26 output lines to connnect 18, 7-segments. i think it can be done with single 40 pin micro

You can use the Multiplexing Technique for reducing the i/o pins......

but multiplexing technique will unnessary increase the  the complexity in that case... simply by using transistors and few i/o pin coding that thing can be done very easily....

you can do this using  Multiplexing techniique.

Go to proteus

 

type

7-seg-mpx8-cc-blue
