Description Deploying YOLOv8 on Wildfire RK3588, we use yolov8s.pt (downloaded from the YOLOv8 official website) as an example. 1. pt->onnx Do not use the official YOLOv8 code; instead, use the Rockchip YOLOv8 code, available at https://github.com/airockchip/ultralytics_yolov8 After downloading the code, execute the model conversion with the following code: from ultralytics import YOLO model = YOLO('yolov8s.pt') … Read more
A common high-speed PCB design rule is to track the return current path of signals. In reality, this is much easier said than done, as the return paths for fast digital signals and even medium-frequency analog signals are largely confined beneath the traces. At very low frequencies or under direct current (DC), the return path … Read more
In the context of intensifying global technological competition and the increasing importance of supply chain security, achieving a full domestic replacement of key software and hardware has become a national strategy and industrial consensus. Against this backdrop, Tactile Intelligence has launched the RK3576 core board, which is the first to adapt to the open-source Harmony … Read more

Introduction: In this revolution of micro-scale manufacturing, templates are discarded, magnetic fields are reinterpreted, and “amber” has become the source of inspiration for structural programming. Image credit: Shan-Gang Wei (Photographer: Wei Shangang) Micro-magnetic-driven flexible devices are crucial for the development and application of minimally invasive medical technology, flexible smart electronic devices, and microrobotics. Despite significant … Read more
UML includes various types of diagrams such as use case diagrams, class diagrams, object diagrams, state diagrams, activity diagrams, sequence diagrams, collaboration diagrams, component diagrams, and deployment diagrams, which are widely used in the stages of requirement analysis, design, implementation, testing, and maintenance in embedded development. The following is a detailed introduction: Requirement Analysis Stage … Read more

Recently, I used FreeRTOS in a project and became curious about idle tasks and hook functions, so I wanted to understand what these two are used for. Here, I will share some of my insights.1. Idle TaskThe idle task is a task that is created by default after the FreeRTOS system starts, and it has … Read more
