Hi @Wheaten No nothing appears on the screen. I’m wondering if the screen if faulty.

450

Hard to tell, you can try to flash Rasbian OS to see if the screen is working. If it is we can debug further what is needed for Volumio.

451

Thanks Wheaten. I’ll give that a go tomorrow. Again, thanks for your help.

Hello, I purchased the Waveshare 7.9-inch IPS DSI Display and tried various configurations with a Raspberry Pi 5, but without success. The screen does not turn on, and a green LED on the back of the screen keeps flashing. Has anyone managed to get it to work?

453

have you added to /boot/userconfig.txt the following lines?

display_auto_detect=1
dtoverlay=vc4-kms-v3d
#DSI1 Use
dtoverlay=vc4-kms-dsi-waveshare-panel,7_9_inch
#DSI0 Use
#dtoverlay=vc4-kms-dsi-waveshare-panel,7_9_inch,dsi0

Hi Fellow Tinkerers,

I have been using a 5" Waveshare with a CM4 for a long time and am wanting to step up to something larger and more functional, from a touch input point of view.

I have not seen a lot of references to the Waveshare 10.1" screen and wonder if any of you are using this, and/or if you see any issue with this version, connected by DSI like my current screen.

Cheers,
Soren

Try replacing your current entries in “/boot/userconfig.txt” with

dtoverlay=vc4-kms-v3d
dtoverlay=ads7846
dtparam=penirq=25
dtparam=penirq_pull=2
dtparam=speed=50000
dtparam=swapxy=0

dtparam=xohms=150
dtparam=xmin=150

bang on, works just needs rotating from portrait to landscape.

Thanks for your help. much appreciated. my experience is programming spectrums and visual basic…Newish to doing much with linux. what was wrong with setting i had originally and why did the ones you provided work? I can seen some of the settings are resolutions and i assume refresh rates?

Try rotating by using the “Display Orientation Settings” on the Touch Display plugin’s config page.

Solved it with …

dtoverlay=vc4-kms-v3d-pi4,nohdmi
dtoverlay=vc4-kms-dsi-waveshare-panel,7_9_inch

Hello everyone,

I’m experiencing an issue with my Waveshare 7" DSI LCD (C) (Product page) on my Raspberry Pi 4 running Volumio 3.785. The display stays black and does not show any output.

My setup:

  • Raspberry Pi 4 Model B
  • Volumio Version: 3.785
  • Display: Waveshare 7" DSI LCD (C)
  • Connected via: DSI interface

Modifications in userconfig.txt:

dtoverlay=vc4-kms-v3d
dtoverlay=vc4-kms-dsi-7inch

The display works fine on Raspberry Pi OS, but not on Volumio. Any help or suggestions would be greatly appreciated. Thanks in advance! :blush:

Try

dtoverlay=vc4-kms-dsi-waveshare-panel,7_0_inchC

instead of dtoverlay=vc4-kms-dsi-7inch.

467 
dtoverlay=vc4-kms-v3d
dtoverlay=vc4-kms-dsi-waveshare-panel,7_0_inchC

Unfortunately it doesn’t work either. Do I need to install drivers or are they already in the kernel?
