I2C Protocol and Device Driver Development. (017)
Abstract
Inter-Integrated Circuit (I2C) Protocol
The Inter-Integrated Circuit (I2C) protocol is a synchronous, multi-master, multi-slave, serial computer bus invented by Philips (NXP). It utilizes only two bidirectional open-drain lines: Serial Data (SDA) and Serial Clock (SCL), minimizing pin count and board complexity. I2C devices communicate using a master-slave relationship. The master initiates data transfer with a START condition, transmits a 7-bit or 10-bit slave address, and awaits an ACK acknowledgment. Data is transferred in 8-bit packets, followed by an ACK/NACK. Its simplicity and low-speed efficiency make it ubiquitous in embedded systems for interfacing low-bandwidth peripherals like EEPROMs, sensors, and real-time clocks (RTCs).
Introduction
Welcome to the hands-on live online course on Linux I2C Driver Development! This 20-hour program is designed to take you from protocol fundamentals to implementing a complete, production-ready I2C device driver from scratch. You'll master the I2C protocol's low-level signaling, bus arbitration, and data transfer mechanisms. We'll then dive deep into the Linux I2C Subsystem, learning the roles of the Adapter, Algorithm, Client, and Driver structures. The hands-on focus includes configuring the Device Tree, implementing kernel APIs, and writing the full I2C Client Driver to interact with a real sensor or memory chip, giving you essential embedded Linux expertise.
Training Objective
The primary objective of this course is to equip participants with the knowledge and practical skills required to develop, debug, and maintain complex Linux I2C device drivers.
Upon completion, participants will be able to:
1. and troubleshoot I2C bus traffic using a logic analyzer;2. Understand and navigate the entire Linux I2C subsystem architecture (Adapter, Algorithm, Client, Driver);3. Integrate hardware using the Device Tree and kernel platform mechanisms; and4. Implement a complete I2C Client Device Driver from initialization to user-space interfacing (ioctl), ensuring full compliance with kernel best practices.This guarantees readiness for professional embedded Linux driver development roles.
