Keys detected as one key

[Wilson-Smith]

I tried to do this project and it was AMAZING. Unfortunately, when I uploaded the code and tried to type on it was strange. When I press a specific key, another key is linked to another key. The keys i'm referring to are:

• s, linked with tab --> s = [ s]; tab = [ s]
• e, linked with q --> q = [qe]; e = [qe]
• z, linked with space --> z = [ z]; space = [ z]
• 1, linked with 3 --> 1 = [13]; 3 = [13]
• 2, linked with 4 --> 2 = [24]; 4 = [24]

I tried to recompile the code, but still the same problem.

Trying the Caps-lock for these letters are just plain useless.

I managed to do "A" using Right Shift, not with the left shift.

I don't know what "linked" means. Let's try bug reporting 101... What keyboard are you using? What action did you take? What result were you expecting? What was the actual result?

Sorry for the waiting.

I'm using a Commodore 64 Original Keyboard, with jumpers in the socket. The action is pressing a single key, but the input is read as a double input. So, If I press the s key on my keyboard, on the notepad is tab+s (this I meant for linked). I was expecting a single output, so for the s-key only the "s" character. The actual result was a double output, so for the s-key both the tab and the s characters,

I hope it can be useful

It looks like you have bad wiring. Do an image search for "c64 keyboard matrix" and notice the positions of your linked keys. Fix the shorted wires and you should be fine.

Thank you a lot!
