Linux I2C in the 21st Century

Explore the evolution and modern challenges of I2C technology in Linux systems through this 32-minute conference talk by Wolfram Sang, I2C maintainer and consultant for Renesas. Discover how contemporary technological advancements impact I2C and its implementation in Linux, including the need for runtime reprogramming of client addresses in multiplexed setups to prevent collisions. Gain insights into the challenges faced by the Linux I2C core and proposed solutions, as well as the rationale behind recent API changes that may be relevant to other subsystems. Learn about new features for stress-testing I2C communication, including unintended writes, and explore both hardware and software debug mechanisms to enhance I2C functionality in modern Linux environments.
