RT-Thread is an open source real-time operating system for embedded devices. It is distributed under the GPLv2 +licence. RT-Thread is developed by the RT-Thread Development Team based in China, after ten years' fully concentrated development. It is aimed to change the current situation in China that there is no well used open source real-time operating system in the micro controller area.

Contents

RT-Thread kernel

  • Object oriented real-time core (while remaining the elegant and flexible style of C Programming Language);
  • 8, 32 or 256 priority scheduling multi-thread scheduling; Using the round-robin policy ensures that all threads having the same priority level will be scheduled equally;
  • Synchronization of threads: semaphore and mutual exclusion semaphore (mutex) to prevent priority inversion;
  • Complete and efficient support for communication between threads, including mailbox, message queues, event flag;
  • Static memory management supports thread suspend/resume when it allocates/frees a memory block and thread-safe dynamic heap management;
  • A device driver framework to provide standard interface to high level application;

    • FinSH shell

  • Command line that accepts C-like expression;
  • Access system core functions directly via command line like C Programming Language grammar;
  • Access system global variables directly via command line like C Programming Language grammar;
  • Command history records and automatic complete for the Command Prompt;

    • Device File System

  • Virtual File System optimised for small device
  • POSIX style API;
  • Support the different implementation of file systems
  • Wrapper for ELM Chan's FatFs filesystem.
