    well...
    Code:
        DEFINE KEYPAD_ROW        8       ' 8 row 
        define KEYPAD_ROW_PORT   PORTc   '   on PORTB
        DEFINE KEYPAD_ROW_BIT    0       '      <7:0>
        DEFINE KEYPAD_COL        4       ' 4 col 
        DEFINE KEYPAD_COL_PORT   PORTc   '   on PORTA
        DEFINE KEYPAD_COL_BIT    0       '      <3:0>
    looking at your schematic bellow

    There's some problems there for sure... You don't use a 8X4 keypad
    Code:
        DEFINE KEYPAD_ROW		4      
        DEFINE KEYPAD_ROW_PORT   	PORTC   
        DEFINE KEYPAD_ROW_BIT	0
        
        DEFINE KEYPAD_COL        	3
        DEFINE KEYPAD_COL_PORT   PORTC
        DEFINE KEYPAD_COL_BIT    	4

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