RT-Thread, short for Real Time-Thread, is an embedded real-time multi-threaded operating system. It has been designed to support multi-tasking, allowing multiple tasks to run simultaneously. Although a processor core can only run one task at a time, RT-Thread executes every task quickly and switches between them rapidly according to priority, creating the illusion of simultaneous task execution. RT-Thread is mainly written in the C programming language, making it easy to understand and port. It applies object-oriented programming methods to real-time system design, resulting in elegant, structured, modular, and highly customizable code. The system comes in a few varieties. The NANO version is a minimal kernel that requires only 3KB of flash and 1.2KB of RAM. For resource-rich IoT devices, RT-Thread can use an online software package management tool, together with system configuration tools, to achieve an intuitive and rapid modular design.
