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.
