Hi Andre,

The same combination is working perfectly for me, what is your exact
problem?

Olin,

The 24LC256 is a I2C EEPROM.

As for your suggestion on using the datasheet alone, I was reading the
datasheet before I physically had the component in hand. Actually, to be
more precise, I ordered the component from the supplier based on the
information I found in the datasheet.

Before joining this mailing list I even emailed Microchip themselves
concerning my problem since BOTH components, the PIC and the EEPROM was
carrying their logo and I at least thought that they would be
responsive.
This was a week ago, and to date I have received NO communication from
Microchip.

If you dont know, as you so elequintly indicated, how to perform this
procedure other than with the information that is in the datasheet then
why
comment and waste valuable bandwidth?

I _have_ exausted every resource I know about before subjecting my
problem
to a mailing list.

What exactly is the problem?  I have connected IIC and SPI EEPROMs to
PICs
several times.  The data sheet should be your most important source of
information, not app notes or other stuff found on the internet.  That's
all I ever used and never had a problem.

I don't know, is that an IIC or SPI EEPROM?
