[SOLVED] DS1307 RTC Interfacing

[jbrathod88]

Hi,

I am here after a serious failure in all my practices done for the interfacing with DS1307 RTC.

First of all I would like to tell you that, I have successfully compiled my code in C for AT89C2051 to communicate with DS1307. I have tried it in Proteus VSM and run successfully.

But now for my project, I have tried to interfacing RTC with AT89C2051 in breadboard. And I have continuously get failed to interface with DS1307.
I have tried to find the reason behind that, and I found that my RTC does not receive the byte and doesn't acknowledges after the transmission of full Address-Byte. I am here 100% sure of that the DS1307 doesn't acknowledge(This is the main problem).

I have send the Address byte (0xD0).
But the device doesn't acknowledges:sad:.

Again I have successfully interface the RTC in Proteus (Except I haven't use the Acknowledge routine in Proteus as Proteus doesn't allow this).

Please help me.
Any suggestion will be appreciate.

Advance Thanks to all.
I hope I will get help.

Here I solved my problem. I am having the low power problem to RTC.
I connect 1uF cap and give the 5.1 volts(Previously given 4.98 volts ). And it run without any problem!..
