I am having a problem with this code. I have made some minor changes. I use R1=R2=R3=R4=1 and I have Columns C1-C4. I also made a change at the end, instead of using P2 as the Output Port, I am using P0. My code builds without any errors, but nothing happens when I press any key. All segments are on and stay on, no mater what key I press.
