Raspberry Pi Picture Frame Bilderrahmen mit Cloud-Anbindung

Endlich habe ich einen Digitalen Bilderrahmen mit Anbindung an die Nextcloud zusammengestellt. Im Folgenden die Anleitung zum durchlesen.

Rpi vorbereiten

Raspbian full (aktuell Debian 10 / buster Base) ohne empfohlene Apps per image auf die SD-Karte spielen. Karte auswefen, wieder einstecken und folgende dateien anpassen:

ssh.txt erstellen – dadurch ist ssh beim boot automatisch aktiviert

Je nach Bildschirm muss dieser gedreht werden. Folgenden Befehl in die config.txt einfach am Ende eintragen. Bei 2 sind es 180 Grad Drehung. Weiterhin ist es sinnvoll, gleich overscan zu deaktivieren.

lcd_rotate=2
disable_overscan=1

WLAN automatischen Connect einrichten. wpa_supplicant.conf auf dem Laufwerk erstellen und mit folgenden Daten füttern:

update_config=1
ctrl_interface=/var/run/wpa_supplicant
network={
  scan_ssid=1
  ssid="<YOURWLANNAMEHERE>"
  psk="<YOURWIFIPASSHERE>"
}

Jetzt speichern und Karte in den rpi stecken. Booten und per ssh verbinden. Standard-Passwort ändern.

Updates aus dem Internet holen und durchführen

sudo apt update && sudo apt upgrade -y

Raspi Grundkonfiguration

sudo reboot
sudo raspi-config
  • advanced – expand filesystem
  • Hostnamen
  • Locale
  • Timezone
sudo reboot

Cloud-anbindung

rclone installieren

sudo apt install rclone -y

rclone konfigurieren

rclone config

Hier eine „new remote“ erstellen – ich wählte den namen „bilderrahmen“ – mit 22 – webdav und den notwendigen Einstellungen. Achtung, bei Nextcloud den richtigen Pfad angeben (bswp. https://xyz.example/nextcloud/remote.php/dav/files/bilderrahmen/ ).

Script „rclone-cron.sh“ für automatische synchronisation erstellen:

nano rclone-cron.sh

Und folgenden Text füttern (Pfade ggf. anpassen):

#!/bin/bash
if pidof -o %PPID -x “rclone-cron.sh”; then
 exit 1
fi

rclone sync bilderrahmen:Pictures-bilderrahmen/ /home/pi/Pictures/
exit

Das ganze ausführbar machen

chmod +x rclone-cron.sh

Cronjob erstellen – edit Cronjob Liste

crontab -e

Folgende Zeile ergänzen (Zeiten selber definieren). In dieser Ausgestaltung alle 15 Minuten Sync mit Cloud.

*/15 * * * * sh /home/pi/rclone-cron.sh

Bilderrahmen

Hier müssen zwei unterschiedliche Vorbereitungen je nach RAM Menge umgesetzt werden.

Raspberry Pi 4

sudo raspi-config nonint do_boot_behaviour B2 && sudo raspi-config nonint do_memory_split 256 && sudo raspi-config

7 Advanced Options > A8 GL Driver > Choose G2 GL Fake KMS

Raspberry Pi 2 und 3

sudo raspi-config nonint do_boot_behaviour B4 && sudo raspi-config nonint do_memory_split 128 && sudo raspi-config 

6 Advanced Options > A2 GL Driver > Choose G1 (Legacy)

Für beide Varianten geht es nun weiter.

pip3 install picframe
sudo reboot
picframe -i .

Per Enter alles bestätigen

Applikation testen mit der Ausführung des folgenden Befehls. Dadurch erscheint das erste Bild auf dem Screen.

picframe ~/picframe_data/config/configuration.yaml

Mit Strg+C beenden

Die config kann hier angepasst werden:

nano ./picframe_data/config/configuration.yaml

Meine Start-Konfiguration sieht folgendermaßen aus:

viewer:
  blur_amount: 10                          # default=12,  larger values than 12 will increase processing load quite a bit
  blur_zoom: 1.0                          # default=1.0, must be >= 1.0 which expands the backgorund to just fill the space around the image
  blur_edges: True                        # default=False, use blurred version of image to fill edges - will override FIT = False
  edge_alpha: 0.7                         # default=0.5, background colour at edge. 1.0 would show reflection of image
  fps: 20.0                               # default=20.0
  background: [0.2, 0.2, 0.3, 1.0]        # default=[0.2, 0.2, 0.3, 1.0], RGBA to fill edges when fitting

  fit: True                              # default=False, True => scale image so all visible and leave 'gaps'
                                          #                False => crop image so no 'gaps'
  auto_resize: True                       # default=True, set this to False if you want to use 4K resolution on Raspberry Pi 4.

  display_y: 0                            # offset from top of screen (can be negative)
  display_w: null                         # width of display surface (null->None will use max returned by hardware)

  outer_mat_color: null                   # default=null, Color of the outer mat as an RGB list. null will auto-select a reasonable color based on the image.
  inner_mat_color: null                   # default=null, Color of the inner mat as an RGB list. null will auto-select a reasonable color based on the image.

  outer_mat_use_texture: True             # default=True, True uses a texture for the outer mat. False creates a solid-color outer mat.

Autostart und fixes

Unclutter installieren, dadurch lässt sich er Mauszeiger deaktivieren:

sudo apt install unclutter -y

Die Autostart Datei des Benutzers „pi“ anpassen:

sudo nano /etc/xdg/lxsession/LXDE-pi/autostart

Folgenden Inhalt einfügen:

#Disable screensaver:
@xset s noblank 
@xset s off 
@xset -dpms
#Disable old settings:
#@lxpanel --profile LXDE-pi #
#@pcmanfm --desktop --profile LXDE-pi
#@xscreensaver -no-splash
#@point-rpi

#Mauszeiger Ausblenden
@unclutter

#Autostart picframe
picframe ~/picframe_data/config/configuration.yaml

Das ganze speichern und die Datei schließen. Reboot und testen.

sudo reboot

Bildschirmschoner ausschalten via:

sudo raspi-config

Display options -> Screen Blanking -> Enable -> No —-> Reboot required

sudo nano /boot/cmdline.txt

Ändern des Eintrags von console=tty1 hin zu console=tty3 Dann speichern und wieder raus in die Console.

echo hide boot messages
sudo sed -i "1 s|$| quiet splash|" /boot/cmdline.txt

echo disable login prompt
sudo systemctl disable getty@tty1.service

echo hide undervoltage message
sudo sed -i "1 s|$| loglevel=1|" /boot/cmdline.txt

sudo sed -i "1 s|$| vt.global_cursor_default=0|" /boot/cmdline.txt

echo hide undervoltage lightning bolt icon
sudo sed -i -e '$aavoid_warnings=1' /boot/config.txt

echo disable splash screen
sudo sed -i -e '$adisable_splash=1' /boot/config.txt

Und jetzt noch den Welcome Wizard entfernen

sudo rm /etc/xdg/autostart/piwiz.desktop
sudo reboot
