Lars Knoll, chief maintainer for the Qt Project, gives a presentation about Qt on embedded systems, including a demo with the Raspberry Pi at the Embedded Linux Conference Europe 2012 in Barcelona, Spain.
For well over 10 years, Qt has been used in many types of embedded devices, ranging from high-end medical systems, through mobile phones and smartphones, all the way to simple devices like coffee makers. This presentation will show some of the work that has been put in Qt throughout the years to support embedded devices, some of the challenges that the development team faced in order to bring a fully-featured desktop toolkit to resource-limited devices, along with solutions they came up with. Time permitting, the presenter will also show Qt demos running on an embedded device.
This session is intended for embedded application developers looking to make use of the capabilities of recent hardware, as well as decision makers looking for technology to enable their product solutions. The presenter is the Qt Chief Maintainer, having worked on and off embedded device development for a decade.
Here are the key sections of the talk:
- Qt Introduction
- A bit of Qt Embedded history – QWS, Qt Palmtop, Qtopia… used in industrial applications, VoIP phones,
- Qt Quick – QML language, easy to bind and extend with C++
- Project Lighthouse & Qt5
- EGLFS & Wayland – For graphics support. EGLFS: Great option for single process UIs if EGL and OpenGL is available. Wayland: Best solution for multi process environment, integrates with other frameworks
- Qt Raspberry Pi Demo
- Qt on Android
