At Open Source Summit North America 2025 in Denver, Luis Ubieda presented RTIO (Real-Time I/O), a relatively new Zephyr subsystem that enables applications to perform time-critical I/O operations. This technical presentation explores how RTIO helps developers meet strict real-time constraints while efficiently managing multiple data streams from sensors, ADCs, and other peripherals.
Presentation Highlights
- RTIO Fundamentals: Understanding what RTIO is and how it enables time-critical I/O operations
- Async vs Sync Paradigms: Exploring the benefits of asynchronous over synchronous approaches
- Practical Examples: In-tree implementations with sensors and bus drivers
- Integration Guide: Step-by-step approach to implementing RTIO in your Zephyr applications
- Performance Comparison: Live demonstration comparing sensor drivers with and without RTIO
