Hex file (download link given at the end of article) to an ATmega8 usingĪ suitable programmer. It also manages the handling of UI (User Interface) by the help of 3 pushĪssemble the circuits according to the circuit diagrams shown above. That uses the above modules to communicate with both the LCD and DS1307 chip.

The full software for the example is written in C language and compiled withĪvr-gcc. :AVR ATmega8 RTC Interface Circuit Diagram. The module can be connected to developmentįig. Will make a small PCB that will hold all these. I will give more details on I2C in a separateĬrystal, a 3v lithium battery and 2 pull up registers to function. The DS1307 and our AVR ATmega8Ĭommunicates using the I2C bus. Is a popular communication protocol between ICs. These functions depends on the I2C library. Uint8_t DS1307Write(uint8_t address,uint8_t data) Uint8_t DS1307Read(uint8_t address,uint8_t *data) Just two functions that allows you to read and write the DS1307 registers. The DS1307.c and DS1307.h provide easy access to order generic viagra the registers. You can read these register to obtain the current time and date. To setup the RTC module with correct time.įrom software point of view the DS1307 is just a collection of some 8 bit registers. Ability to get time from user and store it to DS1307.Format the read data and display in LCD.So the aim of the project will be to access the DS1307 registers, read time The date atĪdjusted for months with fewer than 31 days, including corrections for leap Seconds, minutes, hours, day, date, month, and year information. The DS1307 is a low-power clock/calendar with 56 bytes of battery-backed SRAM.
The DS1307 is described in the datasheet as follows In this tutorial we will learn to use a very famous RTC IC named DS1307. If you have opened yourĬomputer case you will notice a small coin cell in the mother board.

This same technique is used in PC timing also. System with RTC is powered off the RTC module is up and running by the backupĬell. Most case is provided by a miniature 3v lithium coin cell. A very small current is required for keeping the RTC alive. Of battery backup which keeps the clock/ca lender running even in case of powerįailure. The main advantage is that they have a system They are availableĪs integrated circuits (ICs) and manages timing like a clock. Real Time Clocks, as the name suggests are clock modules.
