This post guides developers on setting up Visual Studio Code for Zephyr RTOS application development, starting with installing VS Code and creating an isolated development environment using profiles to avoid conflicts with other extensions. It covers essential extensions like C/C++, CMake Tools, and Serial Monitor, and provides step-by-step instructions for project setup, including creating necessary files and configuring CMake. The author explores different configuration methods, including using `settings.json` for automating build processes and debugging, `CMakePresets.json` for managing multiple build configurations, and `.code-workspace` for a more integrated environment. The post also includes practical examples, such as blinking PWM LEDs and implementing a custom device driver, demonstrating how to leverage VS Code for Zephyr development. By the end, readers will understand how to configure VS Code for efficient Zephyr application development, including building, flashing, and debugging.

This post provides a streamlined guide to setting up a Zephyr real-time operating system (RTOS) development environment, offering an alternative approach to the official documentation. It begins with installing West, Zephyr's meta CLI tool, within a Python virtual environment, followed by downloading the kernel, SDKs, and necessary tools like CMake and the devicetree compiler. The guide then details the manual installation of the Zephyr SDK and building OpenOCD from source for debugging purposes. To ensure everything is set up correctly, the post walks through building and flashing a sample "blinky" application using CMake and OpenOCD. By offering a practical, hands-on approach, this guide helps developers quickly get started with Zephyr RTOS development.

This post introduces Juan Jin, a programmer from South Korea with expertise in C, C++, Python, C#, and TypeScript. Jin's skills extend to platforms, libraries, and frameworks such as STM32CubeMX, ESP-IDF, FreeRTOS, Zephyr RTOS, and more. The author showcases personal projects like "Black Magic," a C macro metaprogramming research endeavor, and contributions to open-source projects like "Net for Dumbass" and "zpmgr." The post also details Jin's extensive work history, including roles at Bitbus, People-i, and other companies, where he developed diverse applications ranging from agricultural smart waterstream projects to military defense systems and IoT solutions. This overview highlights Jin's broad experience and technical capabilities, making it a valuable resource for those interested in embedded systems, IoT, and software development.
