Embedded World, Nuremberg, 24-26 February 2015, Hall 4, Stand 308
The Qt Company showcased the extended functionality of Qt 5.4 for embedded device creation at Embedded World and also demonstrated Qt in action in a range of automotive, industrial automation and IoT applications. Qt was shown as part of a highly configurable SCADA system; as a rapid prototyping platform for intelligent, low-power servo drive systems; and as a backend and frontend component of an industrial communications network that allows user selection via NFC. A highly integrated touchscreen infotainment system demonstrated the power and versatility of Qt in automotive applications; and a weather station proof-of-concept revealed the scalability and flexibility of Qt when deployed across a range of Cloud connected devices in an IoT model. Visitors were also treated to a preview of Qt 5 applications running on Wind River’s VxWorks 7, featuring one-click embedded deployment directly from the Qt Creator IDE.
Qt 5.4 is the latest version of the leading cross-platform application and user interface (UI) development framework. It enables the creation of connected devices and applications with native C++ performance regardless of platform. As the Internet of Things grows, this allows companies to future proof their product development strategy and preserve software engineering investment.
Qt 5.4 introduces significant advances for device creation crucial for a variety of industries most notably automotive, STB/DTV, medical and industrial. The addition of a new Chromium-based browser engine, Qt WebEngine, supports HTML5 hybrid development, future-proofing the integration of web technologies. There are improvements to device creation development with several updates and new features, most notably the Qt Quick 2D Renderer plugin, which enables Qt Quick graphics to run without OpenGL allowing Qt Quick to run on low-end devices without a GPU, as well as the Qt Quick Compiler 2.0 reducing device boot-up time and securing against reverse engineering. Reflecting the growth in development of wearable devices and the Internet of Things, a technology preview of Bluetooth Low Energy support is included. Qt 5.4 also includes an update to its Qt Creator IDE to version 3.3, which introduces an all-new Qt Quick Designer and many other productivity enhancing features.
Qt combines simplicity of development and efficient performance – even on platforms with constrained processing capabilities – with fluid modern UIs. The framework delivers these benefits not only on the initial target platform or device but on all other supported platforms too. Developers can work secure in the knowledge that their investment will be repaid when they wish to support other operating systems or deploy on additional device hardware.
Qt 5.4 further enhances Qt’s ability to bring elegance, functionality and power to the creation of connected devices. Qt’s existing support for creating applications for devices includes powerful C++ libraries, a full embedded tool chain and a pre-built software stack for instant prototyping. Qt 5.4 also introduces a completely new professionally designed “Flat Light” style for Qt Quick Controls that covers traditional and industrial enterprise controls and provides a more polished look-and-feel for application and device UIs.
