what is Zephyr? Zephyr RTOS is a game-changing technology developed by experts with decades of collective experience in the embedded world. Originally created as Rocket by Wind River Systems in 2015 and later rebranded as Zephyr, this open-source project has gained immense popularity since its inception. As an open-source project, anyone can access the source code and understand its internal workings. Over the years, Zephyr has garnered a lot of attention from major tech giants like Google, Meta, Intel, and many more, resulting in significant investments in the project. The depth of contributions by multiple companies can be seen in the commits. Zephyr is not just an RTOS; it’s an ecosystem of a fully-fledged open-source project with strong foundations. ...
