NuttX

NuttX is a real-time operating system (RTOS) with an emphasis on standards compliance and small footprint. Scalable from 8-bit to 32-bit microcontroller environments, the primary governing standards in NuttX are Posix and ANSI standards.

Features

  • Standards Compliant.
  • Core Task Management.
  • Modular, micro-kernel.
  • Fully pre-emptible.
  • Naturally scalable.
  • Highly configurable.
  • Easily extensible to new processor architectures, SoC architecture, or board architectures. See Porting Guide.
  • FIFO and round-robin scheduling.
  • Realtime, deterministic, with support for priority inheritance.
  • POSIX/ANSI-like task controls, named message queues, counting semaphores, clocks/timers, signals, pthreads, environment variables, filesystem.
  • VxWorks-like task management and watchdog timers.
  • BSD socket interface.
  • Extensions to manage pre-emption.
  • Optional tasks with address environments (Processes).
  • Inheritable
