I2C — How Does It Work?

Inter-integrated-circuit, more commonly known as I²C (generally pronounced I-squared-C), is a communication style originally developed by Phillips Semiconductor (now NXP Semiconductor). Its design allows multiple components to be able to talk to each other on the same data line, making it widely used in a variety of systems, including Pmods. As a fan of Pmods, I’m in favor of learning how you can communicate with them and get them what you want to do. Let’s find out more.
