    Default 3x4 matrix keypad

    I have looked at the 16-key serial keypad example from Bruce's website to try and understand how to make my pic scan the keypad. I have a 12 key pad that the column are set up to connect to my 16f628a on B0-B-2 and the rows will connect to B3-B6. That leaves me with B7 set as an input and pulled 5v high with a 10k resistor. I have been trying to modify the code to work with no sucess. Does anyone have any suggestion on what I may be doing wrong. Thanks

    BTW: I am trying to insert a code block instead of just copying and paste to the forum so hopefully this works.
