#include <zephyr/sys/util.h> Concatenate input arguments. Concatenate provided tokens into a combined token during the preprocessor pass. This can be used to, for ex., build an identifier out of multiple parts, where one of those parts may be, for ex, a number, another macro, or a macro argument.

A thread is a set of commands to be executed by the CPU. The while(1) loop that runs inside of the main function of your application is a thread. But Zephyr allows you to create multiple threads. Each thread operates independently, with Zephyr’s built-in scheduler deciding when to run each thread. For example, the Golioth Blue Demo run animations o...
A Zephyr workqueueis a thread with extra features bolted on. It also requires less setup and management than threads. The work queue has a built-in buffer to store pending work (functions you want to run). Each item you add will be executed in the order you submitted it, like a “to-do list” for your processor. This is a perfect place for something ...
A Zephyr Message Queueis a collection of fixed-sized data that is safe to access from multiple threads. You decide what the data is (a variable, a struct, a pointer, etc.) and how many of those objects the queue can contain (limited by your available RAM). Zephyr handles all of the logic necessary for adding to and removing from the queue. Continui...
We often focus on the “ecosystem” aspect of Zephyr, because we like that so many silicon vendors contribute to the code base. But it’s important to remember that Zephyr is a Real Time Operating System and has a fully featured scheduler. We’ve only just scraped the surface of what you can do with it. Hopefully the above explanations helped you to be...

Jan 24, 2024 · Introduction. The Zephyr kernel supports a variety of device drivers. Whether a driver is available depends on the board and the driver. The Zephyr device model provides a consistent device model for configuring the drivers that are part of a system. The device model is responsible for initializing all the drivers configured into the system.
