KDAB at Embedded World 2025

Rust for Embedded

As new regulatory frameworks like the CRA are demanding more safety and security in embedded systems, the interest in Rust is rising. Rust empowers embedded systems with memory safety and performance. Explore how to get started with Rust and how to create Rust applications from scratch or add Rust to existing C or C++ applications.

CXX-Qt - Safe Rust Bindings for Qt

Integration for C++ and Rust applications

KDAB supports and maintains CXX-Qt. A set of Rust crates for creating bidirectional Rust ⇄ C++ bindings with Qt. It can be used to integrate Rust into C++ applications using CMake or used to build Rust applications with Cargo.

Watch our YouTube series "Mixing C++ and Rust" to learn more.

• Enables Rust and C++ ecosystems to be used in the same application
• Allows for idiomatic Rust and C++ code
• Integrates easily into existing applications

Servo WebView for Qt

Servo is a web rendering engine written in Rust

KDAB has built a demo of using CXX-Qt to expose a web rendering engine written in Rust as a component to Qt.

• Uses CXX-Qt to bridge between Qt and Servo
• User interface built with Qt and QML
• Servo renders safely in Rust

Augmenting 3D Support for Machine Control

Interactive 3D rendering using Qt3D

KDAB helped iDig, a provider of excavator machine controls, implement 3D-related work: loading CAD files, mesh data structures and algorithms, and rendering.

Developing Next Generation UI for an EV Charger

High-quality touch-based interface based on Slint

KDAB and tQCS used Slint, a UI toolkit built with Rust, to overhaul the user interface of SK Signet's flagship Electric Vehicle charger. Read more on our website.

Modernizing an Embedded Charge Amplifier UI with Qt

Multi Value Measurements device brought to market readiness

Starting from a legacy codebase, KDAB implemented a multi-measurement channel architecture, extended the UI, and improved stability and performance to reach production quality. The device helps with verification and quality control processes with sensitive measurements in cramped spaces.

Flutter on Texas Instruments AM6254

Improve graphics performance on low power consumption hardware

To optimize graphics performance from 10fps up to 60fps, KDAB enabled Flutter on Texas Instrument hardware using meta-flutter and flutter-pi.

• Image built with Yocto (meta-flutter)
• Optimized graphics performance from 10 to 60fps
• Flutter Embedder (Flutter-pi) for Texas Instruments AM6254
• Quad core Arm Cortex-A53 with GPU

LUMA Vision VERAFEYE

Medical tool for interventional cardiac imaging

LUMA Vision and KDAB developed a fully software-defined, end-to-end imaging system that could adapt to market and clinical needs.
