Incubator Nuttx
NuttX es un sistema operativo en tiempo real compatible con POSIX diseñado para entornos embebidos con recursos limitados. Funciona como un SO de microcontrolador escalable que proporciona un entorno similar a Unix para gestionar hardware y ejecutar aplicaciones en arquitecturas que van desde 8 bits hasta 64 bits.
El sistema garantiza una alta portabilidad del software al implementar un kernel que sigue los estándares POSIX y ANSI. Esto permite a los desarrolladores crear aplicaciones embebidas portátiles utilizando llamadas a la API estandarizadas en diversas arquitecturas de hardware.
El proyecto incluye una arquitectura de kernel modular y una capa de abstracción de hardware para desacoplar el sistema de periféricos de chip específicos. Utiliza programación preventiva basada en prioridad para respuestas deterministas y proporciona herramientas para simular entornos de hardware para probar firmware sin placas físicas.
