Im Controller wird in der Init eine View erstellt und gestartet. Zudem wird der Acquisitionserver | |||||
gestartet, die shared Librarz geladen, die Konstanten Initialtisiert. | |||||
Mittels der Funktion Action Performed wird die jeweilige Reaktion auf die Benutyeraktion ausgeloest. | |||||
Hierfuer stehen die verschiedenen eigenen Funktionen die die Reaktion in der richtigen reihenfolge | |||||
an ein neu instanizieertes Modell weitergibt. | |||||
Zudem stehen einige Funktionen zur Informationsuebergabe an die View oder das Modell zur Verfuegung | |||||

In dem File wird eine Instany des Controllers erstellt. Der Controller ist die Schnittstelle | |||||
zwischen GUI und Modell und koordiniert den Ablauf und die Erstellung der GUI | |||||
''' | |||||

# OpenVibe_THN-p300-bci | |||||
Die Szenarien für das Taktile und das Visuelle BCI, basieren auf dem OpenVibeSzenrio p300-speller-xDAWN. | |||||
In die jeweiligen Ordner können die aktuellen OpenVibe-Dateien für das taktile und visuelle Buchstabieren eingefügt werden. Die Dateien können im EFI-Git gefunden werden. |
Bitte in dem Repository nur Code und keine EEG-Signaldaten hochladen. | |||||
<h1>Grafische Oberfläche:</h1> | |||||
Die grafische Oberfläche wurde in Python geschrieben. Die Pfade von den OpenVibe Programmen sind in einer Shared Library hinterlegt (dll.so, bzw. ddl.cpp). Alle Python Dateien wurden in der Datei "gui" in eine ausführbare Datei zusammengefasst. Die Oberfläche kann durch ausführen dieser gestartet werden. Hierfür werden die Dateien "gui", "dll.so" und "icon.png" benötigt. Diese in den Ordner über meta kopieren. | |||||
Falls zusätzlich eine Desktop Applikation erstellt worden ist, wird noch die "BCI.desktop" und die "start.sh" Datei benötigt. Mittels der "BCI.desktop" Datei kann die Applikation installiert werden. Anschließend wird mit klick auf das Icon die "start.sh" Datei ausgeführt. Diese startet die "gui" und schreibt die logs in eine Textdatei. | |||||
<h2>Nutzungsanleitung</h2> | |||||
* Installation von xdotool und python-tkinter, falls noch nicht installiert (siehe script.sh) | |||||
* Einfügen der taktilen und visuellen OpenVibe Programme | |||||
* Anpassen der Defaultpfade in der dll.cpp Datei (Default-Ordnerstruktur ist im Ordnerstruktur.PNG hinterlegt) | |||||
-> erstellen einer shared library mit g++ dll.cpp --shared -fPIC -o dll.so | |||||
* Fuer den Ablauf werden dann nur die Datei gui, dll.so und das icon (icon.png) benoetigt. Alle Dateien bitte im selben Ordner verschieben (Default im gleichen Ordner wie der Ordner meta). | |||||
* Das Programm kann nun mit den Kommandozeilenaufruf ./gui gestartet werden. (Hier darauf achten das die notwendigen Rechte vergeben wurden) | |||||
<h2>Zusätzlich für Desktop Applikation </h2> | |||||
Fuer den Aufruf ueber ein Desktop Icon werden die Dateien BCI.desktop und start.sh benoetigt: | |||||
* Ggf. die Pfade zur start.sh datei und zum Icon in der "BCI.desktop" - Datei angepassen | |||||
* Pfade in der start.sh Datei anpassen | |||||
* BCI.desktop in den home folder legen und installiert werden | |||||
(sudo desktop-file-install BCI.desktop) | |||||
* start.sh wird mit dem Icon aufgerufen | |||||
<h2>Bei Änderungen der Python Dateien </h2> | |||||
Wurde die Python Dateien verändert muss die "gui" Datei neu erstellt werden. Dies kann im Code Ordner mittels pyinstaller –onefile gui.py durchgeführt werden. | |||||
sudo apt-get install python-tk | |||||
sudo apt-get install xdotool | |||||
sudo apt-get install python-setuptools | |||||
sudo apt-get install python-pip | |||||
pip install pyinstaller==3.6 |
#!/bin/bash | |||||
cd ~/bci/ | |||||
> log.txt | |||||
chmod +rw log.txt | |||||
./gui >> log.txt | |||||
