[SOLVED] Waveshare DSI 7.9 Touch display on Moode 9

[glosolich]

Hi everyone,

Thanks @felix1024 for the wonderful hints on display configuration


just used a slightly altered version of these settings to successfully configure and use a Waveshare 4inch 480 x 800 HMDI display in landscape mode (the display is by standard in portrait mode!). I use Moode on a Raspberry Pi 5, the display is attached via the HDMI port right beside of the USB C port.

I used in cmdline.txt the following code at the end of the line to shape the boot messages/ command line:

Code:

video=HDMI-A-1:480x800@60,rotate=90

And in .xinitrc I added the following lines:

Code:

#somewhere in the beginning before the browser commands are executed and before screensize is set
DISPLAY=:0 xrandr --output HDMI-1 --rotate left
fbset --geometry 800 480 800 480 16

#after the already present SCREENSIZE line
SCREENSIZE="800,480"

Remark:

• all other attempts to set/rotate the screen via config.txt did not work (apparently this cannot be done in bookworm anymore)
  
• I did not setup the touchscreen so far since I do not have the GPIO connections made yet
  

Cheers
