Incubator Nuttx
NuttX est un système d'exploitation temps réel (RTOS) conforme POSIX conçu pour les environnements embarqués aux ressources limitées. Il fonctionne comme un OS de microcontrôleur évolutif qui fournit un environnement de type Unix pour gérer le matériel et exécuter des applications à travers des architectures allant de 8 bits à 64 bits.
Le système assure une haute portabilité logicielle en implémentant un noyau qui suit les standards POSIX et ANSI. Cela permet aux développeurs de créer des applications embarquées portables en utilisant des appels API standardisés à travers diverses architectures matérielles.
Le projet inclut une architecture de noyau modulaire et une couche d'abstraction matérielle pour découpler le système des périphériques de puce spécifiques. Il utilise une planification préemptive basée sur la priorité pour des réponses déterministes et fournit des outils pour simuler des environnements matériels pour tester le firmware sans cartes physiques.
