    Default

    Yes it will stuck, you need some pull-up resistors in that. You can enable the PIC internal one
    Code:
    INTCON2.7=0
    Just saw you already did.. just the wrong way

    AND you WILL have erratic results with this routine... add a PAUSEUS 5 in this section
    Code:
    TRISB = (dcd col) ^ $ff ' Set one column pin to output
PAUSEUS 5
row = PORTB >> 4 ' Read row

    It's not a bug, it's a random feature.
    There's no problem, only learning opportunities.
