Get on the I2C Bus!


I2C: The Kindergarten Classroom of Protocols

Have you ever found yourself daydreaming idly, “If only there was something out there that allowed me the luxury of having several ‘masters’ communicate to several ‘slaves’ on a single embedded device… BUT -- with only two wires?” If so, then prepare to have your dreams come true! What we are going to look at today is a protocol and bus all rolled together called I2C, or more formally, Inter-Integrated Circuit. It’s a handy toolset to understand and have at your disposal as it is utilized in a wide variety of embedded platforms, data acquisition systems, components and sensors. That’s also why we at NetBurner include I2C in most of our embedded Ethernet web servers (core modules) and serial to Ethernet servers, along with an easy to use API – so let us show you how to get the most out of that technology including a code example at the end of the article!
