Qt for MCUs offers extensive support for various pixel formats—8-bit, 16-bit, 24-bit, and 32-bit—and efficient PNG and RLE compression for optimized image storage and transmission.

Powerful Animation Capabilities

Create an interactive, dynamic, smartphone-like UX on any low-end device with a rich set of animation tools. Qt for MCUs supports keyframe animation, built-in animation effects, property animation, and different interpolation methods and easing curves to bring your UI to life.

Long-term Support and Maintenance

Enjoy API stability and a steady roadmap committed to fulfilling our customers' needs. Qt for MCUs' long-term support and backward compatibility ensure your product's market permanence over the years.

Developer Tooling

Boost your software development experience with Qt Creator, a complete and intuitive cross-platform IDE featuring WYSIWYG design, code editor with syntax completion, debugging & profiling tools, and more!

Additionally, Qt for MCUs' tools and workflow integrate seamlessly with the most popular embedded third-party IDEs—such as IAR, Green Hills, and others.

Development Tools

From PC to Target Device

Enjoy the freedom to develop your application on PC even before the actual hardware is ready for deployment. By decoupling UI app development from deployment and testing on target, Qt for MCUs allows great flexibility and major time savings.

Design Tooling

Boost your productivity by importing designs straight from Figma, Photoshop, and other content authoring tools and automatically converting them into functional code. Qt Design Studio allows UI/UX designers to bring their designs to life with compelling animations, simulation tools, and web sharing capabilities.
