10 Aug Learn to design a Real Time Clock using micro controller and DS RTC program is written in Embedded C for Interfacing. The DS Serial Real Time Clock, which incorporates a 2-wire serial interface, can be controlled using an compatible microcontroller. The DS in. 30 Apr Hi friends, Am posting the code here in this code am getting a problem that clock runs quickly without going accordingly with our real time clock please help me.

In the above program, we can. The only concern must be that the 2-wire timing specification is not violated by the low level drivers on the microcontroller.

Saeed’s Blog: Interfacing of with DS (RTC) code + Proteus simulation

In addition to this, data frames also discussed which are used to transfer and receive the data with an appropriate program. Each of these chips can act as a receiver or transmitter, depending on the functionality.


Lets get to the circuit diagram! Source code is on website itself. Kindly provide the clear circuit diagram of above image. Before reading values from the RTC module, we must set sd1307 time and date at once. Hardware requirement — We selected appropriate components with required specifications required for the designing of circuit. We implemented the project in following steps: I2C is the simplest of the buses in this presentation.

However, in this mode, the direction bit will indicate that the transfer direction is reversed.

Interfacing RTC DS Device with Microcontroller

This article is meant to give a little insight regarding RTC DS real time clock interfacing with microcontroller. We studied application of I2C communication. I have not used 80551 7 in this. What is Web Browser.

Real Time Clock using 8051 Microcontroller and RTC IC DS1307

I 2 C Signals. We should pass the actual time details as parameters. Has become a recognized standard throughout our industry.

Skip to main content. In our project, we are using DS in 24 hour mode and we then convert it into 12 hour mode at the software side. Free E-book on how to design your own microcontroller projects- Edgefx kits.


I dont have code for this. D0- D7 of LCD. I used the library of my.

RTC DS1307 interfacing with 8051 in C using I2C…….

Submitted by uddhav dattatra Do you have any idea about this? The master device interconnects with a particular dependent device by an address.

In this library, we included a few functions for initializing LCD, for sending commands and for sending data which is to be displayed. A set of specifications to build a simple universal qith guaranteeing compatibility of parts ICs from different manufacturers: It also displays Date of the month, Month, Day of the week also with leap year compensation valid up to Interfacing interfaciny RTC module to microcontroller is pretty simple.

It will toggle at 1 Hz. The functions that are demonstrated are: Control Status Register Address:
