How to interface Real Time Clock with PIC Microcontroller

                   How to interface Real Time Clock with PIC Micro controller

Real-time clock (RTC):

A real-time clock  is a computer clock (most often in the form of an integrated circuit) that keeps track of the current time. Although the term often refers to the devices in personal computers, servers and embedded systems, RTCs are present in almost any electronic device which needs to keep accurate time.

Interfacing RTC with PIC micro controller:-

Code:

#include<htc.h>

#include"4 BITLCD.C"// for 4bit lcd-click here

#include"I2C.C"// for i2cprotocol-click here

#include"TIME_DATE.C"// for time_date-click here

void main()

{

TRISB=0X00;

TRISC=0X18; // SDI=SCL=1;

lcd_init();

i2c_init();

lcd_cmd(0X80,0);

lcd_str(" I2C BASED RTC ");

lcd_cmd(0X01,0);

lcd_cmd(0X80,0);

lcd_str("TIME:  :  :");

lcd_cmd(0XC0,0);

lcd_str("DATE:  :  :");

set_time(0X00,0X00); // SEC

set_time(0X01,0X01); // MIN

// set_time(0X02,0X64); // HRS & AM/PM

// set_time(0X03,0X04);

set_date(0X04,0X03); // DD

set_date(0X05,0X04); // MM

set_date(0X06,0X05); // YY

while(1)

{

// get_time(0X00,0X8B);

// get_time(0X01,0X88);

// get_time(0X02,0X85);

// get_date(0X04,0XC5);

// get_date(0X05,0XC8);

// get_date(0X06,0XCB);

}

}
