Explore the intricacies of developing an Industrial I/O subsystem driver for new sensors in this 44-minute conference talk. Dive into the world of userspace HALs for efficient data processing, IIO channel consumers and definitions, SW and HW triggers, and ring buffer interfaces. Gain an in-depth overview of the development API for implementing new drivers or enhancing existing IIO drivers. Witness demonstrations of various sensors utilizing IIO functionality, including hrtimer sw triggers and buffered data to userspace HALs. Learn about IO channels, driver structures, scaling, buffers, trigger handlers, and single-shot access. Discover practical examples involving thermocouples, humidity sensors, and capture techniques. Explore consumer channels, API calls, SI units, event monitoring, and buffer data processing. Conclude with a comprehensive demo and Q&A session to solidify your understanding of Industrial I/O concepts and applications.
