Interface of DS1307 with PIC16F876A

[Eng4444]

Maybe you can come up with a new solution for my problem?

i really do not need about making it work for a year or month... not even a week or a full day!

i just want to do a demonstration for 30 minutes and i need to show people who a watching the final number.

so what do you say if i take a second small PIC (12F675 OR 16F84) and run a loop inside it? and then, i take the final number as if it is number of seconds and multiply by it by the Power in PIC16F876... what do you say or suggest?

would it be an accurate number of seconds?

but what to write in that loop? what delay to put.... ?

I hope You or anyone helps me in this affaire...

Maybe this is the best solution to work in peak times? i mean the usage of the second PIC...

any advice is appreciable.
