In high-end HiFi decoders, the digital-to-analog converter (DAC) chip is undoubtedly the “heart”. It determines how cold binary code is transformed into beautiful sound waves. Currently, the competition between Japan’s Asahi Kasei (AKM) and America’s ESS Technology has been ongoing for nearly a decade, with each having its unique advantages. This is far from a … Read more
Click the blue text to follow us In today’s digital age, traditional access control systems can no longer meet the dual demands for security and convenience. This article will introduce a face recognition access control system developed based on MATLAB, which utilizes advanced PCA algorithms and SVM classification technology to achieve an intelligent experience of … Read more
Hello everyone, I am Awei from Mako Control. Some fans have asked me to talk about the scanning cycle of PLCs. The scanning cycle is not as simple as most people think, which involves writing outputs, reading inputs, and executing programs. Most people overlook the core logic hidden behind this, which often leads to writing … Read more
This year, the AI computing hardware sector is booming — leading companies like Cambricon and Foxconn Industrial Internet are frequently hitting new highs, with daily transaction volumes in sub-sectors like optical modules and liquid cooling exceeding 10 billion. The underlying “blood vessels” supporting this computing power revolution — high-speed transmission cables such as AOC, DAC, … Read more
When you wake up in the morning and see the hour and minute hands of the alarm clock stopped between “7” and “12”, you immediately know it is exactly 7 o’clock; you touch your forehead, pick up the thermometer, and see the mercury column stopped at the “38” mark, and you instantly realize you have … Read more

01 Introduction This PWM 360 motor is controlled by PWM signals. Compared to ordinary DC motors, it can control the rotation speed without additional drivers, has high torque, and features stall protection, but its rotation speed is not as fast. 02 Principle The introduction and usage of PWM principles can be referenced in my previous … Read more
One of the three main characteristics of Object-Oriented Programming (OOP) is encapsulation, which C++ implements through access control modifiers <span>public</span>、<span>private</span> and <span>protected</span>. This article will delve into the usage, differences, and practical application scenarios of these three access control modifiers. 1. Basic Concepts of Access Control Access control modifiers determine the visibility and accessibility of … Read more
Abstract Traditional access control integration relies on third-party software interfacing with backend access management systems. Yichuang Technology has innovatively launched a new integration solution: third-party software can directly interface with the front-end deployed HTTP/HTTPS access controllers. This method significantly reduces system coupling and technical implementation difficulty, providing strong support for users to achieve refined management … Read more
