Many integrated circuit-based sensors and output devices offer an interface protocol called Inter-integrated Circuit, commonly abbreviated as I2C. There is tremendous value in using I2C-based components in a microcontroller-based solution that can result in a much more streamlined and robust product, especially if you need to interface with multiple external I/O devices. I2C allows you to share a common data and clock bus amongst multiple devices, thus reducing the I/O pin count and the number of interconnecting wires required to get everything communicating. This blog is an attempt to provide some practical tips on integrating I2C into your next application.
