I've been slowly working my way through Nigel's PIC tutorials and i'm currently working on a project to make a code lock so i've wired up a 3x4 matric keypad the exact same way that's on the site and used the correct tutorial programme but it doesn't work as it should.
I know for certain i've wired it all up the EXACT same way but when i press the keys i get the following results.
1,2,3 don't work
Press 4 and it displays B
Press 5 and it displays 9
Press 6 and it displays 6
Press 7 and it displays 0
Press 8 and it displays 8
Press 9 and it displays 5
Press 0 and it displays A
Press * and it displays 7
Press # and it displays 4
so as you can imagine i'm a bit confused.
Any help would be greatly appreciated.
