as a first step - you could show how you propose to connect the hardware in question and then have a go YOURSELF at writing some code - to at least show that YOU

(a) put in some effort to start with

and

(b) might actually have the chops to do what you inquire about.

as a rule, there are plenty of working professionals on the board who can and HAVE - had to deal with this EXACT sort of thing in the past.

i know i have dealt with SPI drive of the 595 and its higher powered
( TI.COM) TPICxxxx relatives.

And as kindly as i can state this:
I'm not here to do your work FOR you.

Take a look at:

\Program Files\PICC\Examples\EX_EXSIO.C

and

\Program Files\PICC\Examples\EX_DS1307.C


These should give you some information on it as well.

That file doesn't exist.

But there is a ds1307 driver in the Code Library:
http://www.ccsinfo.com/forum/viewtopic.php?t=23255

This example file has some 7-segment LED display code that uses
the 74595.c driver file. Look at the lcd_putd() function:

Oops, my mistake. I had taken that driver and example code you are pointing to and saved the sample program as EX_DS1307.C.
