What’s on the agenda?
5:00 pm – 5:30 pm: Welcome Snacks & Drinks, sponsored by SMIGHT GmbH
5:30 pm – 5:45 pm: Zephyr @ SMIGHT – Anouar Raddaoui, Embedded Software Developer, SMIGHT GmbH
Anouar Raddaoui will walk attendees through SMIGHT’s journey with Zephyr, showing how their grid monitoring product steadily matured over the years, with new features built using Zephyr’s subsystems and capabilities as a reliable and evolving firmware foundation.
5:55 pm – 6:25 pm: Zephyr® in The Matrix: Total Trace for Impossible Bugs – Hugh Breslin, Subject Matter Expert, Microchip Technology
Ever face a bug that defies standard debugging? This talk unlocks the power of full-system simulation to create a complete, deterministic trace of a Zephyr® kernel from time T0. Unlike emulation, simulation gives you total visibility—the equivalent of putting your MCU into The Matrix. You gain the ability to replay and scroll through every instruction, interrupt, and memory access, allowing you to track down race conditions and non-reproducible errors. We will show why simulation provides this unique control to accelerate your most challenging debug tasks. Learn how to wield this capability for when the mystery bugs appear.
6:35 pm – 6:50 pm: Rapid prototype development using Zephyr – Artur Nidens, Freelancer, Nidens Embedded Systems Engineering
A customer sought to explore the feasibility of digitizing an analog meter in a utility setting. Leveraging Zephyr, a functional prototype was successfully developed and delivered within a matter of weeks. This rapid development underscores the efficiency and versatility of Zephyr in creating innovative solutions for modern utility applications.
The presentation is about using Zephyr as a tool to create a prototype. Not about in depth Zephyr details.
7:00 pm – 7:15 pm — Snack Break
7:15 pm – 7:45 pm: Arm Serial Wire Debug Support in Zephyr – Johann Fischer , R&D Engineer, Nordic Semiconductor
Johann will give a brief introduction to Arm Serial Wire Debug and its support in Zephyr. The presentation will provide an overview of the driver API, the GPIO bitbang driver, and USB DAP backend. Johann will also provide guidelines on how to build a debug probe firmware and share insights about future development.
7:55 pm – 8:25 pm: Zephyr in Practice: Mapping Functional Architectures to Zephyr – Tobias Kaestner, Solution Architect Medical IoT, inovex GmbH
Tobias will show how to map from a functional design into Zephyr’s diverse and rich set of components, turning an architectural blueprint into an efficient, real-world implementation. The presented approach puts Zephyr’s strengths front and center: quicker development and faster feedback without compromising on code quality and maintainability. For this he will explore how to
- Use KConfig and the Devicetree to model your system’s features effectively
- Master Zephyr’s core system services for your design
- Build your own services by applying Zephyr’s native design patterns
8:35 pm – 8:55 pm – Quiz and board giveaways
8:55 pm – 9:00pm: Closing Remarks, Zephyr Project team
9:00 pm onwards – Networking time
