keypad help
PostPosted: Tue May 20, 2008 11:55 pm     Reply with quote
hi
i am using kbd.c for a 3X4 keypad. And it is working when i pull up the row pins. But i can only pull up column pins. So what modification in kbd.c I need to get it working with pulled up column pins.

As i think you have access to CCS drivers so i am not posting kbd.c file
however my main file is a test program

Code:
#include <18F4620.h>
#fuses HS,NOWDT,NOPROTECT,NOLVP
#use delay(clock=20000000)
#include <kbd.c>
#include <flex_lcd.c>

void main()
{
   char k;
   lcd_init();
   kbd_init();

   printf(lcd_putc,"\fReady...\n");

   while (TRUE)
   {
      k=kbd_getc();
      if(k!=0)
      {
      if(k=='*')
      printf(lcd_putc,"\f");
      else
      printf(lcd_putc,"%c",k);
      } 
   }
}
