Waveshare DSI LCD displays

I mean with Volumio, did you verify the issue with the touch-panel on Pi5, Pi3B or both?

Fixed previous message. No test with Rpi3b yet.

Ok, it you have time it would be great, because there is always the chance of problems related to the Pi5 only, due to the new HW internal architecture

Sure, I’m going to run a test.

@Darmur test completed with Pi3, display output is working fine but still same issue with touchscreen. It’s definitely an issue with drivers again.I’ve tried all combinations with swapxy, invx and invy, also specifying 0 or 1 value with no luck.

Hello all, I’m in the same situation using the 11.9" DSI screen with an RPi 4 and, after tried every solution I found in this thread, what I’m actually able to obtain is what you can see in those two screenshots:

Volumio is the latest version.
Touch Display is version 3.3.5 (the only one I was able to install without getting an installation error about chromium)
Screen and RPi are powered by two different power supply.
This is what I get if I run the RPi with the standard o.s.:

So RPi, screen and power supply seems to be ok.
Any idea about what’s wrong with my setup?
Thank you in advance.

@AngeloMM please enable test mode and do an OTA update, there is a fixed driver for this display

please be aware that touchscreen does not work yet

@Darmur Dario I really do not how to thank you, your suggestion was absolutely right the screen now works absolutely fine!!!
No problem for the touch not yet working as I can manage Volumio from the smartphone, the big problem was about the display I was almost sure that I did an absolutely wrong purchase but now is fixed thanks to you!!!
Thank you thank you thank you!!!

Yes, @Darmur has his moments of thunder :joy:

Hello. I need help. My card died and I had to install Volumio again. I have an 11.9 inch DSI screen. Volumio has been rebuilt and the Touch Display 3.3.5 plug-in is the only one that can be installed.
Please help me run this display. Step by step. He’s scheming and nothing. I have downloaded the waveshare V1 driver.

As first reflash your SD and DON’T install drivers.
When you’ve setup Volumio enable teat and perform an OTA.
Please read through this topic, I believe the solutions is posted by @Darnur 4 posts back.

I recommend to install version 3.3.8 or you will have serious problems if you should update the plugin somewhen - basically, you will have to be prepared to reinstall Volumio then.

If you can’t install newer versions of the plugin than 3.3.5 this indicates that not all software package the plugin requires succeeded to download - just that versions younger than 3.3.5 detect such failures and abort their installation. Most often a network issue is the reason for failing downloads and changing the repository mirror as described here may help.

I think it is very likely that currently there are software packages missing and the plugin can’t work because of that.

Should you continue to have problems please provide infomation on the Volumio version and the Pi model you use.

I installed the latest Touch Display plug-in, but the screen is still black? The latest system 3.616 and Touch Display 3.3.8

What is your Pi model?

Please post the output of

cat /boot/userconfig.txt

Pi4

Touch Display rotation setting below: do not alter

display_lcd_rotate=1
display_hdmi_rotate=1volumio@volumio:~$

Add

dtoverlay=vc4-kms-v3d
dtoverlay=vc4-kms-dsi-waveshare-panel,11_9_inch

to “/boot/userconfig.txt” and reboot.

The userconfig file looks like this:

Touch Display rotation setting below: do not alter

display_lcd_rotate=3
display_hdmi_rotate=3
dtoverlay=vc4-kms-v3d
dtoverlay=vc4-kms-dsi-waveshare-panel,11_9_inch

The screen now displays a blurry image. What else can I do?

Like this? If so, solution should be in post #261.

I don’t understand? Any additional registry entry?
