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
