Hello sir,I am getting warnings if i put the codes in keil software. Current consumption of this module is nano ampere range. RTC Interfacing with Microcontroller1.

So lets get to business! Primarily, the data transfer sequence initiated by the master generating the start condition.

Interfacing of RTC DS1307 Device with Microcontroller

A battery backup will be provided in case of failure of main power supply by connecting a battery to RTC device. I hope you understood so far!

Add Comment Cancel reply Comment: The port which is to be connected to the data pins of 8501 LCD and the pins which is to be connected to the command pins can be configured rtc ds1307 interfacing with 8051 the library itself. Control Status Register Address: The I2C bus physically consists of 2 active wires.

Have you ever wondered, how your phones and laptops keep track of your time when the device is turned OFF. Your email address will not be published. RTC registers are used to provide calendar functionality and drive time of day and to display the weekends. Mostly, the data transfer sequence introduced by rrc master to generate the start condition. When write operation of the slave device is completed, then the microcontroller sends a stop condition to slave device.


If write operation is performed in the slave device, wifh the receiver sends 1-bit ACK to microcontroller. The address bit rtc ds1307 interfacing with 8051 7-bit, which indicate the slave devices as ds address. Before reading values from the RTC module, we must set the time and date at once. Battery voltage must be held between 2. After completion of write operation in the slave device, microcontroller rtc ds1307 interfacing with 8051 stop condition to the slave device.

Hi Sravanthi I sincerely appreciate your kind response regarding my intetfacing.

interfacing with RTC – Just Execute It

So given below is the circuit diagram to connect RTC module to The address bit includes seven bits, that specify the slave devices as DS address. Below image shows the pin diagram and the recommended connections for DS I2CSend is the function used for sending data and I2Cread is for reading registers.

The control status register1 used to enable the RTC device. Rtc ds1307 interfacing with 8051 module provides intwrfacing such us second, minute, hour, day of week, day of month, month and year including correction for leap year. So let us look on simple RTC interfacing with microcontroller and programming procedure involving in it. Lets get to the circuit diagram!

Interfacing RTC (DS1307) with Microcontroller and its Programming

Interfacing an RTC module to microcontroller is pretty simple. AT89S52 is a typical microcontroller manufactured by Atmel.

Retrieved from ” https: Iwth pins are used to provide the power to the chip.

I2C devices have open drain outputs therefore, a pull-up resistors must be connected to the I2C bus line with a voltage source. Based on the crystal frequency, the RTC device offers years, months, weeks, days, hours, minutes and seconds.

A Real Time Clock module is basically a time tracking device which gives the current time and date.
