Please give us some more clues.

I suggest you read the CCS forum guide.

Tell us which PIC, compiler version etc.

You make them in the main C file, and place the #define statements
above the #include line for the driver file.

See my comments in this thread, which shows how to do it for the CCS
lcd.c driver file:

See my comments in this thread, which shows how to edit your main
source file to set the i/o Port (PortB or PortD) for kbd.c:

Preferably you should put the keypad on PortB, which has internal
pull-up resistors which you can enable (as shown in the link).
Put the LCD on some other port, such as PortD.
