Qt Project first stable release , editions of the Qt 5 framework for microcontrollers and low-power devices. The package allows you to create graphical applications that interact with the user in the style of interfaces for smartphones, for various consumer electronics, wearable devices, 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 using not only the C ++ API, but also using QML with Qt Quick Controls widgets redesigned for small screens.
To achieve high performance, QML scripts are translated into C ++ code, and rendering is carried out using a separate Qt Quick Ultralite (QUL) graphics engine, optimized for creating graphical interfaces in conditions of a small amount of RAM and processor resources.
The engine is designed with ARM Cortex-M microcontrollers in mind 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.
