All these serial things go the same general way: wiggle the clock, set a 
data bit and maybe a direction bit too, wiggle the clock again, either 
read or write the bit, shift the data across. The order in which you do 
this changes from one to another, as do commands and addressing schemes.

Microchip will certainly have examples for the PIC, which is fine if you 
are using the PIC, but even examples in C that are not specific to your 
controller won't help much, as it's all about port access.

I'd recommend reading the comms protocol closely, and converting it to 
pseudo code, then turning this into the actual portwiggling for your uC. 
I've probably got a C example from some years ago (somewhere), but I 
haven't used these for a long time, and IIRC it was specific to the 80C196.

Atmel has notes and assembler examples on their site

Get a data sheet from the manuafacturer.

try microchips site

hi 

anyone has a good site where i can find interfacing the serial EEPROM
with my microcontroller?

the hardware wiring is pretty simple, but i'm also looking as to how
the MC is going to access the 24C04 in terms of software.

any suggestions?
