In embedded system development, developing device drivers is a crucial task. As a bridge connecting hardware and software, the quality of device drivers directly impacts the correctness of system functionality and operational stability. In the rapidly evolving open-source ecosystem, Zephyr RTOS is favored by developers for its lightweight, modular, and highly scalable nature. However, in … Read more
1. Basic Mechanism of Driver Initialization Zephyr’s driver initialization is implemented through the following mechanisms: Device Tree : Hardware resources are defined through the device tree, and the driver relies on this information for initialization. Initialization Macros (DEVICE_DT_DEFINE and DEVICE_DEFINE) : The driver registers to Zephyr’s device model using these macros. Initialization Priority : The … Read more
Robots are not isolated systems; they are a set of distributed sensors and actuators, often running on resource-constrained small embedded devices (microcontrollers) that communicate via wired or wireless connections. However, mainstream robotic operating systems like ROS/ROS2 are too large and heavy, making them unsuitable for robotic scenarios based on microcontrollers with hard real-time requirements. Zephyr … Read more
