1. Basic Concepts Stream buffers are a type of memory buffer specifically designed for FreeRTOS to transmit byte stream data. It is a FIFO (First In, First Out) buffer, but unlike message queues, stream buffers transmit data continuously in bytes rather than as discrete “messages”. Design Purpose To solve the problem of passing variable-length byte … Read more
Comprehensive Report by Electronic Enthusiasts , EtherCAT slave control chips are specialized chips for implementing the EtherCAT data link layer protocol, primarily used for processing EtherCAT data frames and providing data interfaces for slave control devices. In industrial automation scenarios such as servo control, variable frequency drives, industrial PLCs, and industrial robots, EtherCAT offers real-time … Read more
‖ System Learning Life is like a marathon; occasionally stopping to fish allows you to go further. In the field of industrial automation, real-time communication protocols act as the neural center, determining the response speed and synchronization accuracy of the entire system. Among them, EtherCAT and Profinet are two major technical standards that occupy a … Read more
When developing chat applications, stock market updates, or game servers, real-time performance is a crucial requirement. Traditional HTTP requests are one request and one response, which cannot meet the needs of real-time bidirectional communication. At this point, WebSocket shines. WebSocket is a TCP-based network protocol that allows for persistent connections between clients and servers, enabling … Read more
Introduction With the development of robotics, autonomous driving, and industrial control, the demand for real-time and low-latency systems has become increasingly prominent. ROS2 (Robot Operating System 2), as the next generation of robot operating systems, provides better support for real-time performance, especially based on the DDS (Data Distribution Service) communication mechanism. However, ROS2 itself is … Read more
Detailed Explanation of SSE (Server-Sent Events) 🧠 What is SSE? SSE (Server-Sent Events) is a communication mechanism defined in the HTML5 standard that allows the server to actively push events to the client (browser). Unlike traditional HTTP request-response, SSE is a unidirectional streaming communication protocol based on HTTP. 📌 Core Features Feature Description Communication Method … Read more
“I previously wrote a paid column on the architecture of SaaS products for Xiaobaotong, but due to starting a business, I didn’t have time to continue improving it, so it was put on hold. Now I will share the content of the column on the public account, with an expected update once a month. If … Read more
With the rapid development of renewable energy generation, smart grids, and distributed energy systems, the importance of Energy Storage Systems (ESS) is becoming increasingly prominent. ESS requires high-precision, real-time, and reliable communication technologies to support its complex operational demands. The industrial EtherCAT (Ethernet for Control Automation Technology) bus, with its unique advantages, is becoming an … Read more
The high-precision collaborative control and real-time communication capabilities between devices have become performance indicators that cannot be ignored in the manufacturing industry. Recently, the Haptic Intelligence RK3506 core board introduced EtherCAT bus technology, combining a low cost of 59 yuan, a multi-core heterogeneous architecture, and industrial-grade reliability to provide high-performance and cost-effective solutions for the … Read more
In the wave of embodied intelligence, robots are evolving from “programmed mechanical arms” in laboratories to integrated agents of “perception-decision-execution”. In this process, communication protocols act as the robot’s “nervous system”, determining its action precision, collaboration efficiency, and adaptability to various scenarios. The EtherCAT technology represents a core breakthrough in this evolution. Guoxun Chip Micro … Read more
