    Default Hep wanted for keyboard and keypad

    Hi !

    I have a problem and if I could get some help I would be wery greatfull !

    I have a keyboard (10 columns / 4 rows) from Farnell Components with both the usual QWERTY and numerical (4 columns / 4 rows) keypad. The PCB is already designed with pulldown resistors.
    On my PIC16F876A I have PORTA for the rows and PORTB & PORTC for the columns and I can't get it to work !!!

    So if you could be so wery nice and help me out I would be most greatfull !

    Best regards hanseman_61

    Why insist on using 32 Bits when you're not even able to deal with the first 8 ones ??? ehhhhhh ...

    IF there is the word "Problem" in your question ...
    certainly the answer is " RTFM " or " RTFDataSheet " !!!
