Qt Project gepresenteerd<\/a><\/noindex> bewerkte framework voor microcontrollers en low-power apparaten \u2014 Qt voor MCUs<\/a><\/noindex>. De voordelen van het project zijn de mogelijkheid om grafische toepassingen te cre\u00ebren voor microcontrollers, met gebruik van de vertrouwde API en ontwikkelaarstools, die ook worden gebruikt voor het maken van volledige GUI's voor desktopsystemen. De interface voor microcontrollers wordt gemaakt met niet alleen de C++ API, maar ook door gebruik te maken van QML met widgets van Qt Quick Controls, aangepast voor kleine schermen die gewoonlijk in consumentenelektronica, wearables, industri\u00eble apparatuur en slimme huissystemen worden gebruikt. <\/p>\n

Om hoge prestaties te bereiken, worden QML-scripts omgezet in C++-code, en de rendering gebeurt met behulp van een aparte grafische engine, die is geoptimaliseerd voor het maken van grafische interfaces onder omstandigheden van beperkte RAM- en processorbronnen. De engine is ontwikkeld met het oog op ARM Cortex-M microcontrollers en ondersteunt 2D-grafische versnellers, zoals PxP op NXP i.MX RT chips, Chrom-Art op STM32 chips en RGL op Renesas RH850 chips. Voor testing is momenteel alleen beschikbaar een demonstratiebuild<\/a><\/noindex>.<\/p>\n

\"De<\/a><\/noindex><\/center><\/p>\n

Daarnaast kan worden vermeld creatie<\/a><\/noindex> onafhankelijke enthousiastelingen van de Qt5-poort voor het besturingssysteem OS\/2. De poort omvat alle essenti\u00eble onderdelen van de QtBase-module en is al geschikt voor compilatie en uitvoering van een groot aantal bestaande Qt5-toepassingen in OS\/2. Van de beperkingen wordt opgemerkt dat er geen ondersteuning is voor OpenGL, IPv6 en Drag & drop, de mogelijkheid om de cursorafbeelding te wijzigen ontbreekt, en er is onvoldoende integratie met de desktop. <\/p>\n
