Image Processing for Microcontrollers with libmpix // Zephyr Tech Talk #027
2025-07-16 15:00 - 16:00 UTC
Tune in on Wednesday, July 16 (9:00 AM EDT / 3:00 PM CEST) for a new Zephyr Tech Talk live stream!
The Zephyr video subsystem has seen a flurry of improvements recently, but processing image data efficiently on resource-constrained devices remains a real challenge.
libmpix is a lightweight open-source library that brings common imaging operations—like pixel format conversion, debayering, blurring, sharpening, resizing, and color correction—to microcontrollers. It’s designed to reduce memory overhead and has Zephyr support out-of-the-box 🪁. In this new Zephyr Tech Talk episode, Benjamin Cabé will be joined by Josuah Demangeon, co-maintainer of the Video subsystem in Zephyr and author of libmpix, to discuss video support in Zephyr and how to add libmpix to the mix for advanced image processing.

Zephyr on Arduino? Arduino on Zephyr? // Zephyr Tech Talk #028
2025-11-20 15:00 - 16:00 UTC
Tune in on Thursday, Nov. 20 (9:00 AM EST / 3:00 PM CET) for a new Zephyr Tech Talk live stream!
Arduino has been around for over two decades and its simple programming model has been helping countless makers and developers bring their ideas to life. But what happens when you want the ease of Arduino alongside the power and flexibility of a real-time operating system?
In this new Tech Talk episode, we will be chatting with Martino Facchin and Leonardo Cavagnis from Arduino about the bridges that exist between Zephyr and Arduino, from being able to use Arduino APIs and libraries with any Zephyr-supported board, to how the official Arduino cores are leveraging features such as Linkable Loadable Extension (LLEXT). Whether you’re an Arduino veteran curious about real-time applications or a Zephyr user excited by Arduino community and hardware ecosystem, join us live and ask your questions to our speakers.

Zephyr 4.3 - Live Community Q&A // Zephyr Tech Talk #029
2025-11-26 15:00 - 16:00 UTC
Zephyr 4.3 is out and, as always, this release is packed with lots of new features and enhancements. We are offering you a chance to learn about some of the highlights of the release and to directly ask any questions you might have about the release to our release managers Chris Friedt, P.Eng. and Johan Hedberg. Tune in on Wednesday, November 26th!

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.

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!

Cellular IoT Projects with Zephyr and the nRF9151 MicroMod Processor // Zephyr Tech Talk #032
2026-03-25 15:00 - 16:00 UTC
The nRF9151 MicroMod Processor is a board that brings LTE-M, NB-IoT, and GNSS to SparkFun’s MicroMod ecosystem… and it runs Zephyr! In this Tech Talk, Benjamin Cabé will be joined by its creator, Christian Hirsch, to explore how open hardware and Zephyr’s connectivity stack can dramatically lower the barrier to building real-world cellular IoT applications.
As always, we’ll skip the slides and dive straight into a discussion and live demos (and traffic lights might be involved!). Since the board is also about to launch on Crowd Supply, we’ll get a chance to discuss the journey from prototype to open hardware campaign, and what’s next for the project.

JavaScript for Embedded with Moddable & Zephyr // Zephyr Tech Talk #033
2026-04-08 15:00 - 16:00 UTC
Moddable is an open source SDK for building embedded applications in JavaScript. In this new Zephyr Tech Talk episode, Benjamin Cabé will be joined by Peter Hoddie to discuss how Moddable brings JavaScript to embedded systems, and how its recent Zephyr port exposes standard lightweight JavaScript APIs on top of a solid RTOS foundation.
As always, we’ll skip the slides and go straight to discussion and live demos! We’ll even show what Blinky looks like in JavaScript, along with a broader look at the features already supported, including display controllers, networking, GPIO, and more.
