Design and Control of a Quadruped Spider Robot Using ESP32
This article is a continuation of "Design and Control of a Quadruped Spider Robot Using ESP32 (Part 1)"
ESP32 Quadruped Spider Robot Circuit Diagram (8 Servos)
This circuit diagram illustrates the integration of 12 servos, allowing the robot to move in various directions.
The robot consists of four legs, with each leg connected to two servos. One servo is responsible for axial rotation (called pivot servo), while the other servo controls
Understanding CPU_FAN, SYS_FAN, CHA_FAN, and CPU_OPT Interfaces on Motherboards
During the process of assembling a computer, although the installation is simple, problems often arise with the connections. Many users mistakenly plug the CPU cooler power cable into the SYS_FAN port. Although the fan may spin, you might encounter an F1 error message "CPU Fan Error" when starting the computer, and it also prevents the CPU cooler from intelligently adjusting its speed. Below, we share knowledge about the CPU_FAN, SYS_FAN, CHA_FAN, and CPU_OPT interfaces on computer motherboards.

Getting Started with C# NanoFramework Development on ESP32
Last time we had a brief introduction to ESP32 and the official examples. For more in-depth understanding, you can visit the official website of Anxin Ke.
Of course, it has a clock speed of up to 240MHz, external FLASH of 4M, which is sufficient for use, and it also comes with WIFI and Bluetooth, along with about 40 IO ports.
The most important thing is that the ESP32S model development board is only 27 yuan, and it includes free shipping.
After buying it,

Understanding VxWorks Multitasking and Inter-Task Communication
Introduction to VxWorks
Before learning VxWorks, readers are expected to have a foundation in computer networks, operating systems, C/C++, and network communication. It is recommended to read CSAPP to build a solid foundation. VxWorks is a high-performance real-time operating system launched by Wind River Systems in the USA, which is now widely used in various large-scale projects. Companies like Tplink also use VxWorks as the operating system for certain routers. Real-time systems are divided into hard real-time and soft real-time, with
Arduino Launches 9-Core Portenta X8 and Portenta Max Carrier for Rapid Prototyping
Makers can quickly turn their ideas into real products.Exploring the Potential of Mini LED Display Solutions in Automotive Applications
With the rapid development of smart cars, in-vehicle displays, as an important window for human-computer interaction, have been evolving continuously with their unique technology applications. High resolution, high brightness, high contrast, high color saturation, low power consumption, fast response speed, thin thickness, and long lifespan have become the quality requirements for a new generation of high-quality in-vehicle displays.
From the perspective of display technology, OLED and Mini/Micro LED self-luminous direct display technology will become the ultimate display solution in the future.
Flagship Laptop with MiniLED Flip Screen
In the notebook screen field, the most common types are LCD and OLED screens, with the former being more prevalent and the latter being an emerging configuration.(For notebooks)
Today, our protagonist is the ROG Zephyrus 16 Flip version, which is rare in adopting a miniLED screen, its biggest advantage isbrightness, with a peak brightness of1100nit(typical value), suitable for watching HDR videos and playing large games that support HDR effects.
So how does this computer perform in real-world testing? Let’s do a brief
Common Embedded Operating Systems
In embedded system development, choosing the right operating system (OS) is crucial. Different embedded operating systems have different characteristics, resource usage, and applicable scenarios. Here are some commonly used embedded operating systems and their brief introductions:
1. Real-Time Operating Systems (RTOS)
1. FreeRTOS
• Introduction: FreeRTOS is an open-source real-time operating system widely used in microcontrollers and small embedded systems.
• Features:
• Lightweight, with minimal kernel resource usage.
• Provides basic RTOS functionalities such as task management, queues, semaphores, and
