Hi,
I need a digital clock circuit with following specifications:

1. Operated with DS1307 RTC
2. 7 segment displays with both time(HH:MM:SS format) & date(DD:MM:YY format)
3. Source code is needed to edit it.
4. Must have alarm function.


If anyone can show link to any website or provide any data, it will be very helpful....

Re: Digital clock needed

Its a good circuit, but I dont want to use LCD's. I already have a complete project of this type. I want to use 7 segment led's as I mentioned in my specifications...

You've omitted several important specifications:

What microcontroller is the project to be based?

What language is the source code to be written, Assembly, C language, etc?

And if a high level language, what compiler?

Re: Digital clock needed

I have omitted those points because those were not so important to me. Any uC or any language can do. However, 8051 architecture and assembly language would be great.

I am asking for a 'pre-made' circuit and not designing it by me because I am not good in programming. I can make the schematic, pcb, but not the program.
 

Re: Digital clock needed

Id be happy to make it for you.
