On May 23, 2024, Zephyr Project enthusiasts gathered at the inovex GmbH office in Karlsruhe, Germany, for an insightful meetup focused on the latest advancements and insights within the Zephyr ecosystem.

Here’s a recap of the sessions that took place:

From Concept to Prototype: Building the inoCube with Zephyr RTOS

David Zerulla from inovex GmbH started the evening by detailing the journey of developing the inoCube using Zephyr RTOS. The inoCube, based on the Thingy52 development board, showcases various functionalities including temperature sensing, motion data collection using the MPU9250 sensor, and Bluetooth Low Energy (BLE) data transmission to a mobile app. David highlighted the integration of drivers and example code, along with the challenges and straightforward aspects encountered during the development process.

Zephyr’s New Hardware Model

Christian Kurz from Nordic Semiconductor introduced attendees to Zephyr’s latest hardware model, introduced shortly after the release of Zephyr 3.6.0. This presentation provided valuable insights into the new features and enhancements of the hardware model, emphasizing its significance for developers working with Zephyr.

How I Fell in Love with Zephyr – A System Architect’s Tale

Tobias Kästner, from UL Methodpark, shared his decade-long journey and experiences with system and software architectures for medical devices. Tobias emphasized the transformative impact of technologies like Kconfig and Devicetree on hardware and software collaboration. He illustrated real-world examples where system models and Devicetree have streamlined development processes, offering a glimpse into the future possibilities for Zephyr in industries like medical devices.

Device Trees in Zephyr – Navigating Hardware Diversity

Stefan Kratochwil, also from inovex GmbH, delved into the concept of device trees within Zephyr. Drawing parallels with the Linux kernel, Stefan explained how device trees facilitate the decoupling of operating systems from hardware specifics, enhancing portability and scalability across different platforms. He showcased practical implementations and highlighted their role in a Zephyr showcase developed at inovex.

Step up with Zephyr

Jilay Pandya and Dipak Shetty from Zeiss Medical Technology presented on the ongoing development of a motor controller API within the Zephyr ecosystem. They discussed the collaborative efforts within the Zephyr community to refine and enhance the API, making it more scalable and maintainable for future applications.


During the meetup, participants actively discussed topics, shared ideas, and dived into innovative Zephyr community projects. The event also included a table where attendees could explore and interact with the newest evaluation boards presented by Nordic Semiconductor.
