The Book of I2C. A Guide for Adventurers

If you work with embedded systems, you’re bound to encounter the ubiquitous Inter-Integrated Circuit bus (IIC, I2C, or I²C) — a serial protocol for connecting integrated circuits in a computer system. In The Book of I²C, the first comprehensive guide to this bus, bestselling author Randall Hyde draws on 40 years of industry experience to get you started designing and programming I²C systems.

For hardware hackers, electronics hobbyists, and software engineers of every skill level, the extensive coverage in this book will make it a go-to reference—whether you need an overview of I²C signal protocols, an introduction to variants of the I²C, like the SMBus and VESA E-DCC, or programming examples for common I²C peripheral ICs. You’ll also learn the I²C implementations of the Arduino, Teensy, and Raspberry Pi systems among others, as well as how to:

- Analyze and debug I²C bus transactions

- Program devices on the I²C

- Implement an I²C with bare-metal programming

- Work with I²C bus expanders

The Book of I²C includes over 100 figures and many annotated source code listings, along with online chapters that will be updated to include new controllers and peripherals.
