How does Mjølner use Zephyr?

Mjølner is committed to being the preferred supplier for physical digital prototypes, with a strong focus on rapid prototyping, multi-source design, and security. To deliver on this commitment, we use the Zephyr platform for: 

  • Supporting our Multi Source Design strategy and to strive to deliver solutions that are as vendor- and hardware-agnostic. 
  • It allows us to provide our clients with the flexibility and adaptability needed in today’s fast-paced tech environment.
  • Enabling us to offer robust solutions that align perfectly with our customers’ diverse needs, ensuring rapid prototyping and enhanced security in every project we undertake.

Converting virtual to real products


Why limit ourselves to the real world, where things breaking is costly, and everything has to be done in real time, if we can recreate our stuff virtually, where it can break a million times at a thousand times the speed, at only the cost of a few joules?
This presentation presents one way to develop a zephyr application for a virtual device in a virtual environment, which we then deploy to a real device in the real world.

How to Build Stunning Embedded UIs with Zephyr


Explore the integration of Qt for MCUs with the Zephyr RTOS, showcasing how to build a connected product from a constrained embedded environment. This session demonstrates the addition of a graphical user interface (GUI) on top of MQTT, Bluetooth, and Wi-Fi connectivity.

Finally, it highlights the use of Squish automated testing to ensure reproducible and reliable validation of embedded graphical interfaces.

CANnectivity: Zephyr-based USB to CAN adapter firmware


A key element in developing firmware with Controller Area Network (CAN) communication is a host-connected CAN adapter. Existing commercial and open-source options have limitations. The Zephyr-based open-source CANnectivity firmware for USB-to-CAN adapters aims to overcome these.

This presentation covers the motivation for its development, intended use cases, benefits over current solutions, its architecture, validation through automated testing, and future enhancements.

CANnectivity is available here.

The Transformative Power of Free Software


The idea of “Free Software” has reshaped software development for decades. Once mainly visible to developers, it now influences broader society by challenging monopolies and siloed systems controlled by big tech.

Looking at the rise of GNU/Linux, I will discuss how these transformations extend to everyday devices through the Zephyr OS for microcontrollers, and speculate on future developments. The talk balances technical detail with accessibility for all audiences.

A deep dive into Zephyr’s Bluetooth LE controller and the ULL/LLL layers.


The Bluetooth controller is one part of the Bluetooth stack in Zephyr that handles some of the most complex parts of the Bluetooth Core Specification, and serves as a bridge between the physical layer and the Bluetooth Host layer. This talk consists of the architecture, constraints, and some use cases to better understand how it all works.
