Course Overview
This course offers a deep dive into Linux Inter-Integrated Circuit (I2C) drivers, covering their development and integration into the Linux kernel. Participants will learn the I2C protocol's architecture, Linux I2C subsystem APIs, and debugging techniques. Hands-on labs provide practical experience in writing and troubleshooting I2C drivers for embedded systems.
