Kann nicht erfolgreich starten Kivy-Anwendungen auf Raspberry Pi 3 mit 3,5 in Touchscreen

Question

Ich folgte jeder Anleitung, die ich bei der Installation von Kivy Raspberry Pi finden konnte.

Mein Touchscreen funktioniert ganz gut, ich glaube nicht, dass Kivy nicht richtig startet, hat etwas damit zu tun.

Der Versuch, verschiedene Kivy-Demos zu starten, führt scheinbar zu einem teilweisen Start, aber dann hängt es einfach ... vielleicht ist meine config.ini nicht richtig konfiguriert?

Zum Beispiel: 'Python main.py' für Beispiele/demo/Bilder Laufen/gibt mir:

Und dann immer hängt er einfach. Kein Fenster erscheint, nichts.

Die gleiche Sache geschieht vom Touchscreen, läuft durch SSH, und läuft durch tightvncserver Remote Desktop.

Update: Keine guten Nachrichten, aber einige weitere Details. Laufen mit einer nackten Knochen Anwendung (https://kivy.org/docs/guide/basic.html#quickstart) mit einem Tastatur-Interrupt:

Meine beste Vermutung ist, dass es entweder das fehlende ffpyplayer Modul oder etwas mit EGL zu tun.

Update 2: Nun, ich wiederholte die grundlegende Anwendung in meinem Windows Kivy, um das Protokoll zu vergleichen (die Anwendung wird erfolgreich in meinem Windows Kivy gestartet). Der ffplayer-Fehler existiert immer noch und lässt mich glauben, dass es sich um eine Art EGL-Problem handelt.

Answer 1

Vielleicht hilft Ihnen das tutorial. Es verwendet denselben Controller wie Sie (ADS7846). Überspringen Sie einfach den GPIO-Teil. Es gibt einen Teil, wo der [Eingabe] Abschnitt in der Datei ~/.kivy/config.ini geändert wird:

mouse = mouse 
mtdev_%(name)s = probesysfs,provider=mtdev 
hid_%(name)s = probesysfs,provider=hidinput 

Answer 2

i zur Zeit das gleiche Problem mit einem Eleduino 10,1 Zoll kapazitiven Touchscreen mit Blick auf bin. Ich habe es geschafft, das Problem zu lösen, die Datei zu konfigurieren: ~/.kivy/config.ini Gehen Sie zum Abschnitt [Eingabe] und kommentieren Sie alles. Dann fügen Sie die folgenden Zeilen hinzu:

test = mtdev,/dev/input/event3 
    ntrig = mtdev,/dev/input/event1
