There are 3 push buttons on the circuit to change the time and the time is displayed over the LCD display. In this project we dont take care about the days and we just use the time functions. This RTC chip has inbuilt oscillator for clock and it has its own registers for full calender. This project gives you a real time clock with the RTC chip DS1307. Initialize Now we can initialize the RTC with the code below. We do not use any other bits from it, so you need not worry. The address 0x07 is a control registered as described below: 7 6 5 4 3 2 1 0 OUT 0 0 SQWE 0 0 RS1 RS0 We write 0x00 to Control register to disable SQW-Out. #define C_Ds1307ReadMode_U8 0xD1u // DS1307 ID #define C_Ds1307WriteMode_U8 0xD0u // DS1307 ID The RTC keeps the date and time arranged in it's memory as shown below: ADDRESS FUNCTION RANGE 00h Seconds 00–59 01h Minutes 00–59 02h Hours 01-12/00-24 03h Day 01–07 04h Date 01–31 05h Month 01–12 06h Year 00–99 07h Control 08h to 3Fh RAM 00h–FFh Write to the addresses above we can set the time, and once we set it, we can read it any time we need. Well, basically we can use a micrcontroller to keep time, but the value would go off as. The Real time clock DS1307 IC basically is stand alone time clock. It also tells weather we want to write to or read from the RTC. The first thing that the MCU sends to the slave (RTC) is the device ID. For details of I2C in AVR, go through tutorial. Check the here, if you are not familiar with it. It is uses I☬ ( Inter-Integrated Circuit) protocol, referred to as I-squared-C, I-two-C, or IIC for communication with the micrcontroller. The RTC DS1307 is a handy solution to keep time all the way, when it is powered by a coin cell. Well, basically we can use a micrcontroller to keep time, but the value would go off as soon as it is powered off. Basics The Real time clock DS1307 IC basically is stand alone time clock. ![]()
