NXP's Zephyr OS - Summary Page (Japanese Blog)

There's a relatively new RTOS that's been attracting attention recently. It's called "Zephyr ® OS," pronounced "Zephyr."

Zephyr OS is an open-source RTOS that has seen a surge in development cooperation and support from world-renowned companies, and NXP has been a platinum member since Zephyr's inception.

This page compiles helpful information for using Zephyr OS, so please make use of it.

Zephyr ® Series (Steps to get started with Zephyr OS)

Step	article
1	[Zephyr ® Series] Part 1: What kind of OS is the recently popular Zephyr OS? (Japanese Blog) →First, let's learn about the features of Zephyr OS itself.
2	[Zephyr ® Series] Part 2: First Build and Testing (Japanese Blog) →Let's actually build and run Zephyr OS. We'll use FRDM-MCXA153 as an example, but the same procedure can be used with other boards.
3	[Zephyr ® Series] Part 3: First Steps in Blinking an LED and Software Reusability (Japanese Blog) →Using an LED blinking program as an example, experience the difference between "traditional hardware-dependent coding" and "Zephyr's recommended hardware-independent (scalable) coding."
4	[Zephyr ® Series] Part 4: Overview and Practical Applications of Kconfig and Device Trees (Japanese ... →For traditional MCU software engineers, "Kconfig" and "device tree" are unfamiliar aspects of Zephyr OS. These will be explained with practical examples.
