Building future-proof, hardware-agnostic, embedded applications can be a challenge. This challenge is even more significant in IoT scenarios, where multiple processes such as sensor data collection and processing, server communication graphical user interfaces, etc. need to work together seamlessly. Soon enough, the limitations of single-threaded applications become apparent.
Fortunately, real-time operating systems (RTOS) provide a powerful solution. Among them, the Zephyr Project is a notable RTOS offering an open-source solution targeting various hardware architectures including Cortex-M (like SAMD21, Arduino Uno Minima, STM32), Tensilica Xtensa (such as ESP32), and RISC-V. Designed for devices with limited resources, Zephyr is also developed with a strong focus on security.
Dive into the world of ‪@ZephyrProject‬ RTOS with our detailed guide, designed for developers of all skill levels. This tutorial takes you from the basics of setting up your Zephyr development environment, through running your first "Hello World" application, to more advanced examples like LED blinking on various devices.
