Hi!

It sounds like your system is displaying a battery indicator overlay. To remove it, try the following based on your setup:

If Using EmuELEC or Batocera:
Go to Main Menu > UI Settings and look for an option related to battery display.
Some themes have battery indicators enabled by default—switching to a different theme may remove it. If Using RetroPie on a Handheld Device:
If you have a script generating the overlay, check your /opt/retropie/configs/all/autostart.sh file for any battery-related commands.
You can disable any script running cat /sys/class/power_supply/BAT0/capacity or similar. If Using a Custom Theme in EmulationStation:
Some themes hardcode battery icons. Try switching to a different theme under UI Settings > Theme.
If the icon is part of the theme, you may need to edit the theme’s XML files (located in /etc/emulationstation/themes/your_theme).
Let me know what system you're using, and I can give more specific steps! 😊

Hello @mtd

Yep, one needs to modify its /boot/recalbox-user-config.txt by adding:

dtoverlay=vc4-kms-dsi-7inch

and /boot/cmdline.txt with:

video=DSI-1:800x480@60,rotate=180

at the end of the existing line.

I think I will create a new "case" to automate those 2 settings.

@lexx0006
Danke für die Rückmeldung !
Schön das es jetzt funktioniert 😌

Vielleicht hilft das:

Ansonsten vielleicht einfach hier

mal nachsehen ob sich eine Lösung findet

I may have misunderstood some of the translation. I mixed the files and this worked for me.

Thank you for the help

@conan Erstens haben Sie nicht das richtige Modell des Bildschirms angegeben, den Sie verbinden möchten, daher kann ich nicht einmal behaupten, dass er mit Recalbox kompatibel ist.

Wenn es ein Bildschirm ist, wenn er über HDMI angeschlossen wird, sollte es funktionieren, es sollte höchstens notwendig sein, den Videomode in der Datei recalbox.conf zu bearbeiten oder in der Datei config.txt zu konfigurieren, der Link, den ich Ihnen gegeben habe, führt Sie dorthin Tutorials.

Das einzige mir bekannte Tutorial, das einen Bildschirm dieser Größe erwähnt, ist dieses:
https://recalbox.gitbook.io/documentation/tutorials/video/tft/setting-up-your-small-tft-screen-on-the-spi-bus#pourquoi-lecran-tft-capacitif-resistif-de-3-5-de-waveshare-nest-il-pas-utilisable-avec-recalbox

Aber wie gesagt, es besteht die Möglichkeit, dass dieser Bildschirm nicht kompatibel ist. Wenn kein Treiber dafür vorhanden ist, funktioniert er unabhängig von der Konfiguration nicht.

@zing thanks for the links but I already read them. And doesn't explain how to activate the screen throu DSI port.
