display keypad value to a lcd

[lgeorge123]

I wrote a c program to display keypad value in a certain format . there are two cases:
1>> when I press '.' then a value, say 7, lcd display '0.7V' or
2>> when I press '1' then a value, say 2, lcd dispaly '1.2V' .
I compile this c program well and connect to power supply, 'hello' is display but whatever i press the keypad , no data is display.
#include <16f877.h>
#include "c:\program files\picc\drivers\kbd.c"
#use delay(clock=4000000)
#include <lcd.c>
#fuses XT,NOWDT,NOPROTECT,NOLVP
char c,c1;

void main(void)
{
port_b_pullups(true);
kbd_init();
lcd_init();
lcd_putc('\f');
printf(lcd_putc,"hello");
while(1)
{
c = kbd_getc();
if(c!=0)
{
switch(c)
{
case '.': c1=kbd_getc();
if(c1!=0)
{
lcd_putc('\n');
printf(lcd_putc,"0.%cV",c1);}
break;
case '1': c2=kbd_getc();
if(c2!=0)
{
lcd_putc('\n');
printf(lcd_putc,"1.%cV",c2);
}
break;
}
}
}
}

What port is the LCD connected to ?

What port is the keypad connected to ?


Port B or Port D ?

lcd to portb, keypad to portd
I sure both keypad and lcd hardware are functional well.

Sorry, lcd is to portd, keypad is to portb.

I also write a simple to test the keypad working or not.
main()
{
port_b_pullups(true);
while(1)
{
c=kbd_getc();
if(c!=0)
{lcd_putc('\n');
lcd_putc(c);}
}
it display all value whatever I enter using the same hardware.
