Qt Project first stable release , a version of the Qt framework 5 for microcontrollers and low-power devices. The package allows for the creation of graphical applications that interact with users in a style similar to smartphone interfaces, suitable for various consumer electronics, wearables, industrial equipment, and smart home systems.
Development is carried out using the familiar API and standard developer tools used to create full-fledged GUIs for desktop systems. The interface for microcontrollers is created not only using the C++ API but also utilizing QML with Qt Quick Controls widgets, redesigned for small screens.
To achieve high performance, QML scripts are translated into C++ code, and rendering is performed using a separate graphics engine, Qt Quick Ultralite (QUL), optimized for creating graphical interfaces in conditions of limited RAM and CPU resources.
The engine has been developed with an eye toward ARM Cortex-M microcontrollers and supports 2D graphics accelerators such as PxP on NXP i.MX RT1050 chips, Chrom-Art on STM32F769i chips, and RGL on Renesas RH850 chips.
