I2C Bus What is it and how many people will it seat?

I know it a standard and not big and yellow, but can someone tell me what it is, and if the bs2sx is compatible with it. I'm look at getting a TPA81 8x1 Thermopile array, and it states I2C compliance. Before I spend $100 +/- on it I want to make sure that I can and know how to get it to work with a stamp. From what I can tell it will be pretty easy to connect. it even has a Servo controller on it. I've searched the stamp manual and the web all I find is parts that are I2c compatible. I'm not sure what that tells me. Can some one point me to a site or tell me what it is.

Philips Semiconductor invented I2C and has the patent on it. It's now NXP and you can look for parts and (most importantly) application notes here: www.nxp.com/products/interface_control/i2c/index.html.

The BS2sx doesn't have the built-in I2C commands that the BS2p models have, but it can do I2C using subroutines. Have a look at the Nuts and Volts articles on using I2C with the Stamps. They're downloadable for free as is most of Parallax's educational literature. Start with column #85 here: www.parallax.com/html_pages/downloads/nvcolumns/Nuts_Volts_Downloads_V3.asp.

That should get you started.
