IntroductionIn the previous article (Getting Started with Zephyr: Saving Data to Files), I demonstrated how to create an application using the Zephyr project RTOS to store data on a microSD card. A microSD card allows embedded systems to store large amounts of data. When there is no internet connection or the cost of frequent data … Read more
The article on Zephyr device drivers and their implementation explains that device drivers are general and reusable code modules. For the same type of device, regardless of how many instances there are, the driver code is the same. For example, on the ESP32, there are multiple ADC devices, and these ADCs are identical in hardware, … Read more
Introduction In the previous two articles (Getting Started with Zephyr: Devicetrees and Getting Started with Zephyr: Devicetree Bindings), I demonstrated the “Devicetree” in the Zephyr Project real-time operating system. Through the Devicetree, we can describe the hardware in the system to the operating system. As mentioned in the first article, Zephyr supports many popular System-on-Chip … Read more
