Multiplexing 7-Segment

[ross246]

Common cathode is common negative or ground so by assigning it 0's your making it negative so switching it on

EDIT: assigning the cathode itself negative which is connected to portb, by assigning the segments (portc) 0's yea that would blank them.

Ah by clearing portc which is connected to the segments i have solved the problem thanks so much guys

Hi Ross,

Glad you got it to work. Now you can move on to not displaying any leading zero's.
Very nice code by the way, much more efficient than what I came up with a few years back.

Regards
Bob...
