In the previous articles, we used freestanding applications and relied on a global Zephyr installation. In this article, we’ll see how we can use West to resolve global dependencies by using workspace applications. We first explore West without even including Zephyr and then recreate the modified Blinky application from the previous article in a West workspace.

Installation on Linux has been greatly simplified in the upcoming Tracealyzer v4.9. The installation package now includes everything needed to run the software. Linux users no longer need to install dependencies like Mono or libgconf. Instead, a native Linux binary is provided (for x86-64) with the Mono runtime integrated. Most other dependencies have been replaced or removed. You are up and running in a few minutes. We have also spent a lot of time improving the overall user experience on Linux.

The Internet of Things (IoT) is all the rage these days, and for good reason. It lets us connect all sorts of devices to the internet, opening up a world of possibilities. However, managing all those devices and the data they generate can be a challenge. That's where AWS and MetricFire come in. AWS offers a robust suite of cloud services called AWS IoT that makes it easy to develop and manage IoT applications. MetricFire is a platform that helps you monitor your AWS services, including your IoT devices.

After a long pause, I had the pleasure to once again walk the show floors of Embedded World in Nuremberg. It was nice to meet both old and new faces, and to get a thorough update on where the industry is heading.

April marked the return of the Embedded Open-Source Summit, this year in Seattle. I was lucky enough to be able to attend and split my time between the Memfault booth in the exposition hall and many of the captivating presentations. Since the videos have just been published on the the Linux Foundation’s YouTube account, we thought it would be a good time to highlight some of the talks and give you a quick summary which will, hopefully, inspire you to go watch them!

Earlier this month, I had the pleasure of traveling to Nuremberg, Germany to attend Embedded World. If you have not heard about it before, Embedded World1 is the largest trade show in the embedded systems industry. This year, over 35,000 people attended and 1,100 businesses exhibited at the Nuremberg Messe.

In the previous articles, we covered Devicetree in great detail: We’ve seen how we can create our own nodes, we’ve seen the supported property types, we know what bindings are, and we’ve seen how to access the Devicetree using Zephyr’s devicetree.h API. In this fifth article of the Practical Zephyr series, we’ll look at how Devicetree is used in practice by dissecting the Blinky application.
