Projet Qt pr\u00e9sent\u00e9<\/a><\/noindex> \u00e9dition du framework pour microcontr\u00f4leurs et appareils \u00e0 faible puissance \u2014 Qt pour MCUs<\/a><\/noindex>. Parmi les avantages du projet, on note la possibilit\u00e9 de cr\u00e9er des applications graphiques pour microcontr\u00f4leurs, en utilisant l'API et les outils de d\u00e9veloppement familiers, \u00e9galement utilis\u00e9s pour cr\u00e9er des GUI compl\u00e8tes pour des syst\u00e8mes de bureau. L'interface pour microcontr\u00f4leurs est cr\u00e9\u00e9e en utilisant non seulement l'API C++, mais aussi en appliquant QML avec des widgets de Qt Quick Controls, repens\u00e9s pour les petits \u00e9crans, g\u00e9n\u00e9ralement utilis\u00e9s dans l'\u00e9lectronique grand public, les dispositifs portables, les \u00e9quipements industriels et les syst\u00e8mes de maison intelligente. <\/p>\n

Pour atteindre des performances \u00e9lev\u00e9es, les sc\u00e9narios QML sont traduits en code C++, et le rendu est effectu\u00e9 \u00e0 l'aide d'un moteur graphique distinct, optimis\u00e9 pour la cr\u00e9ation d'interfaces graphiques dans des conditions de faible m\u00e9moire vive et de ressources processeur. Le moteur a \u00e9t\u00e9 d\u00e9velopp\u00e9 en tenant compte des microcontr\u00f4leurs ARM Cortex-M et prend en charge les acc\u00e9l\u00e9rateurs de graphismes 2D, tels que PxP sur les puces NXP i.MX RT, Chrom-Art sur les puces STM32 et RGL sur les puces Renesas RH850. Actuellement, seule une version de d\u00e9monstration<\/a><\/noindex>.<\/p>\n

\"Pr\u00e9sentations<\/a><\/noindex><\/center><\/p>\n

Il convient \u00e9galement de noter la cr\u00e9ation<\/a><\/noindex> des passionn\u00e9s ind\u00e9pendants du port Qt5 pour le syst\u00e8me d'exploitation OS\/2. Le port comprend toutes les parties principales du module QtBase et est d\u00e9j\u00e0 pr\u00eat pour la compilation et l'ex\u00e9cution d'un grand nombre d'applications Qt5 existantes sur OS\/2. Parmi les limitations, on note l'absence de support d'OpenGL, d'IPv6 et de fonction de glisser-d\u00e9poser, l'impossibilit\u00e9 de changer l'image du curseur de la souris et une int\u00e9gration insuffisante avec le bureau. <\/p>\n
