This blog post is a continuation of our series of blog posts on Zephyr, in which we already discussed Getting started with Zephyr, Understanding Zephyr’s Blinky Sample, and Zephyr: implementing a device driver for a sensor.
In this fourth blog post in our series, we will see how to add support in Zephyr for the display panel available on the STM32L562E-DK board.
This post is our third blog post in our series about Zephyr. You can check our previous episodes: Getting started with Zephyr and Understanding Zephyr’s Blinky Sample. In this third blog post, we will see how to implement a device driver for Zephyr, from the configuration of the build system, the code of the driver itself, to contributing the driver upstream.

After our initial blog post on Zephyr in which we discovered how to download, build and flash Zephyr on two different boards, in this second blog post, we will dive into the code of Zephyr to understand how exactly the Blinky example works. To illustrate this, we will use the same boards as in our last blog post: an Arduino Nano 33 BLE, and a STM32L562E-DK.
We will first look at how the example application determines which LED to blink and where it’s plugged in, and then we will look at the code responsible for blinking the LED.
Zephyr is an open-source real-time operating system, used mainly in embedded devices, with a focus on small systems, thanks to its very small footprint.
This post is a quick startup guide to show how to run Zephyr on two different boards, from two different vendors:
In this post, we will show how to install all the tools needed to build and run Zephyr, then run some samples, until we get access to the Zephyr shell over USB.
