</pre>
The root file system also provides a lot of pre-built demos and examples (with the related source code and project files), contained in the following directories:
* /home/dvdk/delk/rfs/tisdk/usr/bin/qtopia/demos
* /home/dvdk/delk/rfs/tisdk/usr/bin/qtopia/examples
The Matrix-Gui application (http://processors.wiki.ti.com/index.php/Matrix_Users_Guide) that launched automatically after DIVELK startup is based on QT and can directly show some demos (simply touching the QT icon). Moreover, additional examples can be launched, for example the "calculator" QML demo:
<pre>
/etc/init.d/matrix-gui-2.0 stop
cd /usr/bin/qtopia/demos/declarative/calculator
./calculator -qws
</pre>
