3x4 numpad/keypad problems!
I am a student currently working on a combinational lock problem, using 68k assembly language. I have no idea how to use the numpad, or get numbers to 7 segment display, we need to scan the rows and columns of the numpad, then display the relevant number on a series of 7-segment displays. Any help that could be offered would be greatly appreciated.
