RT-Thread/rt-thread
Rt Thread
RT-Thread is an IoT real-time operating system and embedded device kernel. It provides a lightweight execution environment for microcontrollers, combining a real-time kernel with a hardware abstraction layer to manage multi-threaded task scheduling and hardware resource allocation.
The project is built as a modular framework that utilizes a package-based ecosystem. This allows for the integration of reusable software libraries and high-level services through a loosely coupled architecture.
The system covers real-time task scheduling, resource-constrained memory management, and embedded hardware abstraction. It includes a unified device driver framework for peripheral access across different CPU architectures and supports hardware execution simulation for testing firmware logic without physical hardware.
