A Visual Approach to Devicetree Configuration // Zephyr Tech Talk #030
2025-12-17 15:00 - 16:00 UTC
Devicetree is a powerful way to describe hardware, but things can quickly turn into a maze of DTS files and overlays. Keeping track of pins, buses, interrupts, and board-level constraints by hand is error-prone and hard to review.
In this new Tech Talk episode with Maxim Gorinov (Embedd.it) , we’ll look at a graphical approach to building Devicetree configurations. We’ll walk through a structured component model and visual editor that help you navigate peripherals, pins, interrupts, buses, and dependencies, while keeping the generated Devicetree clear and maintainable. Whether you’re regularly wrestling with complex Devicetree setups or just curious about more visual workflows for Zephyr-based designs, this session should give you practical ideas and patterns you can bring back to your projects.
Zephyr Tech Talks are live streams organized by and for the Zephyr community. Join us live to ask your questions directly to our guests, or catch the recording anytime afterward.

Edge AI on Constrained Devices with Edge Impulse & Zephyr // Zephyr Tech Talk #031
2026-01-14 15:00 - 16:00 (Europe/Paris)
Adding machine learning capabilities into a firmware project can be tedious as one needs to not only enable and configure an inference SDK (e.g., LiteRT for Microcontrollers) but also import (and keep in-sync!) their trained model every time the dataset changes or the model architecture evolves.
In this Tech Talk, Benjamin will be joined by Eoin Jordan and Francesco Varani from Edge Impulse to discuss how to streamline this workflow using dedicated West commands, effectively turning the AI pipeline into a native part of your regular Zephyr build process. As always, expect many live demos and hardly any slides!

Zephyr Project Meetup (March 18, 2026) - Jena, Germany
2026-03-18 17:30 - 21:00 UTC
Meet Zephyr – Moderne MCU-Applikationen am Beispiel des CAN Bus
Von Zephyr zu CANnectivity – eine Safari durch moderne Werkzeugketten.
Im Rahmen unseres nächsten Meetups in Jena – einem weiteren Hands-on-Workshop – nehmen wir dich mit auf eine Reise durch Beispiele, Tests und fertige Applikationen aus dem Makrokosmos rund um das „Zephyr RTOS Project“. Aus den unzähligen Zephyr Treiber APIs und Subsystemen werden wir uns an diesem Abend intensiver mit der bestehenden CAN-Bus Implementierung beschäftigen. Fokus wird dabei auf der konsequenten Nutzung der vorhandenen Hardware-gnostischen Software und deren Architektur liegen – nicht nur von Zephyr, sondern auch der noch jungen, aber durchaus schon sehr prominenten Zephyr Downstream Applikation „CANnectivity”.
Auch dieses Mal arbeiten wir nur minimal im Editor. Stattdessen analysieren wir „guten” und „schlechten” Zephyr-Applikationscode, diskutieren bewährte Architektur- und Vorgehensmodelle und grenzen diese von weniger geeigneten Ansätzen ab. Darüber hinaus zeigen wir, wie Zephyr als Technologie zur Kostenoptimierung im Entwicklungsalltag beiträgt und wie mithilfe moderner Entwicklungswerkzeuge MCU-Software vollständig ohne konkrete Zielhardware entwickelt werden kann.
Tobias Kästner von der inovex GmbH aus Karlsruhe wird uns mit seinem Impulsvortrag das Konzept von „Zephyr Downstream” vorstellen und daran reflektiert einige freie Zephyr Applikationsprojekte (Produkte) bewerten – unter anderem auch „CANnectivity”.
Stephan Linz von der Navimatix GmbH aus Jena führt euch dann durch den praktischen Workshop. Ihr integriert dabei „CANnectivity” auf ein FRDM-MCXN947 Entwicklungsboard von NXP, baut dieses mit zusätzlichen Aufsteck-Boards um weitere CAN-Schnittstellen aus und lernt die einzelnen Integrationsschritte mit den bestehenden und immer gleichen Zephyr Werkzeugen, Beispielen und Tests abzusichern.
Der Abend wird mit einer kleinen Live-Demonstration enden. Dabei wird gezeigt, wie die am Abend genutzte Applikationssoftware in geeignete Simulations- und Emulationsumgebungen integriert und, zusammen mit realer Elektronik, diese auch zu Hybridaufbauten überführt werden kann.
