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

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.

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

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
