An introductory course to experience the entire flow of embedded development, from Linux installation to robot control. When starting with embedded systems, it can be overwhelming to know where to begin. This course is designed for those people, structured so you can experience the entire process—from a single PC to moving a robot—all at once. We cover everything from Linux installation, basic configuration, and Raspberry Pi preparation to reading schematics and datasheets, as well as hands-on practice with basic communication interfaces. The focus is on understanding the overall structure rather than deep technical complexity.

Through this lecture, you can systematically learn core concepts such as an overview of readv/writev, understanding struct iovec, utilizing readv, utilizing writev, and performance considerations.

You know what Linux is and have learned some basic usage methods, but do you want to use the Linux shell better? Do you need to write Linux shell scripts? Well, it's time to learn Linux shell scripts!

AI Tech DNA Series: Core Principles of Computer Basics from an AI Perspective is an introductory course designed to help you easily understand the fundamental computer concepts necessary for the AI era.
