Hi everybody
I cannot to set real time clock on keypad!!
....please to solve my code...
thank you very much.
| Code: | #include <16F887.h>
#include<LCD.c>
#include<input.c>
#use i2c(master,sda=PIN_C4,scl=PIN_C3)
#define ADDR_DS1307 0xD0
unsigned char scankey(void)
{
unsigned char m = 0;
unsigned char key;
//--------------------------------------------- col3-row1-4

{
delay_ms(m);
key='1';
