If you look at the notes about the Ace kit, it refers to the keyboard header 'connecting to port B'. Hence it is almost certainly designed to use the internal 'resistors' in the PIC (current sources really, but serving the same purpose here). You will need the line 'port_b_pullups(TRUE)', to turn these on.

Ttelmah has established that the ACE kit uses PortB for the keypad.
To make it work, add the following modifications to your program,
as shown below in bold. The new lines in should be placed in the
exact locations shown below:
Quote:

#include "flex_lcd.c"

#define use_portb_kbd TRUE
#include <kbd.c>

void main() {
char c;

port_b_pullups(TRUE);

lcd_init();
kbd_init();
