1. Design Concept For controlling the LED light, we can imagine the functions of the LED light. The first is the switch, brightness, and color, which are the main three functions. How can we abstract these three functions? Regardless of what the underlying LED device is, we can abstract it using this structure. As shown … Read more
1. What Sparks When C++ Meets Embedded Development? In our daily lives, electronic products come in various forms, from smartphones and smartwatches to electronic control systems in cars and automation equipment on industrial production lines. Embedded systems are truly ubiquitous. They act as the “hidden brain” of these devices, silently controlling everything, often with high … Read more
Real-time operating systems (RTOS) that meet real-time control requirements are introduced below. Here are 14 mainstream RTOS: μClinux, μC/OS-II, eCos, FreeRTOS, mbed OS, RTX, Vxworks, QNX, NuttX, and domestic embedded operating systems include Dujiangyan Operating System (djyos), AliOS Things, Huawei LiteOS, RT-Thread, and SylixOS. Below are the characteristics of these fourteen embedded operating systems. 1. … Read more

1. What is RTOS RTOS (Real-Time Operating System) is an operating system specifically designed to handle real-time tasks. It provides a way for embedded systems to manage tasks, schedule tasks, handle interrupts, and deliver real-time performance. Unlike general-purpose operating systems (like Windows or Linux), RTOS focuses on meeting the response time requirements of real-time systems. … Read more
