'[STAMPS] What is I2C interface?'

It's a simple but powerful standard of interface which allows any
number (within reason - something like up to 256) I2C devices to
connect together in a network, all connecting to a bus made up of
just two wires. The I2C protocol allows any device on the bus
to talk to any other, because each device has a unique ID address.
PICs are generally used on I2C, but you can also get things like
serial EPROM/RAM/EEPROMs, AD/DA converters and other chips with
I2C control, and you just access them as you would a PIC or any
other device. The interface you're talking about doesn't sound
like I2C to me, because I2C only has two lines, and the chip
selection takes place one of the two data lines.
If only Basic Stamps had an I2C command....... <HINT HINT>
I have an I2C data sheet in I2C format if you're interested. Let me
know if you'd like me to email you a copy - it's about 210kb.
