Raspberry Pi 3 + Display Rotation

Benze8 · Oct 30th 2017

Hallo,

ich habe ein Problem mit dem Display von kedei und deren Imagedatei.

Ich möchte gerne die Anzeige um 90° drehen.

Die Befehle die ich aus dem Internet gefudnen habe funktionieren nicht.

in der setting Datei habe ich folgende Zeile ganz unten, wie in mehreren Foren beschrieben eingefügt:

lcd_rotation = 1 // 90° Drehung der Anzeige

leider ohne Erfolg. Ist da bei der Pi3 etwas anders?

Bitte um Hilfe

Hallo Benze8,

lcd_rotation = 1 oder lcd_rotate = 1 ? Ich habe beide Schreibweisen im Netz gefunden.

Übrigens habe ich hierauch gelesen, dass lcd_rotate = nur bei Displays funktioniert, die per DSI angeschlossen sind. Ob das nun für Dich zutrifft, kann ich sagen. Dafür bist Du zu geizig mit Deinen Infos...

Hallo Hyle,

vielen Dank für die Antwort.

Ich habe beide Schreibweisen ausprobiert.

kedei Screens werden über die GPIO Pins betrieben, somit ist es wohl der falsche Befehl.

Vielleicht weiß noch jemand einen Rat?

Moin Benzo8,

wenn du dir mal deine /boot/config.txt mit einem Editor ansiehst, dann solltest du sowas finden

Code

hdmi_force_hotplug=1
                      <-- Hier bitte display_rotate=1 einfügen
hdmi_drive=2
hdmi_group=2
hdmi_mode=87
hdmi_cvt 480 320 60 6 0 0 0

Es kann auch sein das "1" nichts ändert. Dann bitte mal 2 oder 3 probieren.

Gruss Bernd

Hallo DG8BR,

vielen Dank für den Hinweis.

bei mir sieht das ganze bisschen anders aus..

ich habe in meiner setting datei nicht die Reihenfolge wie bei dir gelistet. Zudem ist vor den Befehlen immer noch ein #-Zeichen vorangestellt.

2 #-Zeichen bedeuten wohl Kommentar`?

So sieht das bei mir aus -->

Code

#hdmi_force_hotplug=1
#display_rotate=2

## hdmi_ignore_hotplug
##     Pretends HDMI hotplug signal is not asserted so it appears a HDMI
##     display is not attached
##
##     Value    Description
##     -------------------------------------------------------------------------
##     0        Disabled (Default)
##     1        Use composite mode even if HDMI monitor is detected
##
#hdmi_ignore_hotplug=1

## hdmi_drive
##     chooses between HDMI and DVI modes
##
##     Value    Description
##     -------------------------------------------------------------------------
##     1        Normal DVI mode (No sound)
##     2        Normal HDMI mode (Sound will be sent if supported and enabled)
##
#hdmi_drive=2

## hdmi_ignore_edid
##     Enables the ignoring of EDID/display data
##
#hdmi_ignore_edid=0xa5000080

## hdmi_edid_file
##     Read the EDID data from the edid.dat file instead of from the attached
##     device

##     1        Read EDID data from edid.txt file
##
#hdmi_edid_file=1

## hdmi_ignore_edid_audio
##     Pretends all audio formats are unsupported by display. This means ALSA
##     will default to analogue.

##     Value    Description
##     -------------------------------------------------------------------------
##     0        Use EDID provided values (Default)

Lösch da einfach die Raute (#) vor display_rotate=2, dann sollte auch was passieren.

Achso und ja, eine oder mehrere "#" zum Zeilenanfang macht die Zeile zu einem Kommentar, deshalb sagt man auch "auskommentieren" dazu.

Hallo Hyle,

die komplette config.txt Datei hat #-Zeichen vorangestellt.

Ich habe es auch ohne #-Zeichen nun probiert, aber es hatte keine Auswirkung.

Hier mal die komplette Config-Datei:

##  Overclocking Settings
##
##  ARM, SDRAM and GPU each have their own PLLs and can have unrelated
##  frequencies.
##

##  frequencies.
##  pll_freq = floor(2400 / (2 * core_freq)) * (2 * core_freq)
##  gpu_freq = pll_freq / [even number]
##
##  The effective gpu_freq is automatically rounded to nearest even integer, so
##  asking for core_freq = 500 and gpu_freq = 300 will result in divisor of
##  2000/300 = 6.666 => 6 and so 333.33MHz.

Hallo Benze8,

bist Du sicher, dass das die richtige Datei ist? Eine "normale" /boot/config.txt würde in etwa so aussehen:

Code

# For more options and information see
# http://rpf.io/configtxt
# Some settings may impact device functionality. See link above for details

# uncomment if you get no picture on HDMI for a default "safe" mode
#hdmi_safe=1

# uncomment this if your display has a black border of unused pixels visible
# and your display can output without overscan
#disable_overscan=1

# uncomment the following to adjust overscan. Use positive numbers if console
# goes off screen, and negative if there is too much border
#overscan_left=16
#overscan_right=16
#overscan_top=16
#overscan_bottom=16

# uncomment to force a console size. By default it will be display's size minus
# overscan.
#framebuffer_width=1280
#framebuffer_height=720

# uncomment if hdmi display is not detected and composite is being output
#hdmi_force_hotplug=1

# uncomment to force a specific HDMI mode (this will force VGA)
#hdmi_group=1
#hdmi_mode=1

# uncomment to force a HDMI mode rather than DVI. This can make audio work in
# DMT (computer monitor) modes
#hdmi_drive=2

# uncomment to increase signal to HDMI, if you have interference, blanking, or
# no display
#config_hdmi_boost=4

# uncomment for composite PAL
#sdtv_mode=2

#uncomment to overclock the arm. 700 MHz is the default.
#arm_freq=800

# Uncomment some or all of these to enable the optional hardware interfaces
#dtparam=i2c_arm=on
#dtparam=i2s=on
#dtparam=spi=on

# Uncomment this to enable the lirc-rpi module
#dtoverlay=lirc-rpi

# Additional overlays and parameters are documented /boot/overlays/README

# Enable audio (loads snd_bcm2835)
dtparam=audio=on

Deine Datei hat zwar 1190 Zeilen, aber nur zwei "freigeschaltete" Konfigurationen und zwar in den Zeilen 399 und 409. Gibt es von der Herstellerseite (kedei) keine Infos zur Konfiguration ihrer Images bzw. Displays?

BTW: Um was für ein Display handelt sich's denn überhaupt und wie wird es am RPi angeschlossen? Und welches OS (Betriebssystem) ist das Image?

Hallo Hyle,

ich habe bei meinem Händler nachgefragt, leider konnten die mir nicht weiterhelfen..

Zu deinem Code, da ist ja auch das meiste auskommentiert mit einem #. Erst in Zeile 56 ist ein wirksamer Befehl?!

Das Display ist von KEDEI anbei alle Informationen.

bestell link: ebay

Software link: kedei

Gerade gesehen, dass es für die Vertkale Ausrichtung auch eine Image-Datei gibt. Allerdings steht da HDMI?!, geht ja nicht über HDMI.. ich teste es heute abend mal..

Hallo Benze8,

Quote from Benze8

das stimmt, ich wollte Dir nur eine config.txt zeigen, wie sie normalerweise bei einem Raspbian aussieht. Der Hersteller hat sich da offenbar bei eLinux bedient.

Apropos kedei, da liest man im Netz ja die wildesten Sachen ... Auf der Suche nach "kedei+SPI+rotate" bin ich hierauf gestossen: https://github.com/saper-2/rpi-spi-lcd35-kedei Hoffentlich hilft Dir das irgendwie weiter, denn ich habe leider auch keine bessere Antwort.
