I recently published here a short post about TwoMusic, an open source music player for ownCloud. As I got interested in embedded systems and embedded development the last few weeks, I turned the player into a project for the Raspberry and other boards that run Linux. My first goal was to boot directly into a minimal Linux system that supports Qt and its multimedia module. The book “Embedded Linux lernen mit dem Raspberry Pi” was a very helpful introduction about the whole procedure, and I recommend it to anyone who reads German.
In the end I came up with my first embedded Linux system that boots the Qt music player with touch screen support. To reflect the focus on embedded platforms and especially the Raspberry I changed the project name to “Die Brummbeere”. The documentation of the project on GitHub now contains a longer description about how to build your own embedded system that boots Die Brummbeere, so I won’t go into details here. As a summary, with all the work that is done around Linux, the Raspberry, Qt and buildroot, it was amazingly easy to build your own embedded device. I really felt like on the shoulders of giants during the development of the project and hope to be able to give back in the future…
Die Brummbeere still runs on desktop computers (and probably mobile phones), but the user interface does not really integrate into anything existing. My goal over the next weeks is to understand the cross-platform opportunities of Qt regarding user interfaces better. Maybe develop some kind of responsive approach to Qt GUIs that allows to share most of the QML code. I really like what Microsoft presented as their Continuum approach, I am very curious how you could mimic that with Qt.
