Have this 3.5 LCD. Working very well. It stands with the connector facing down (lower right corner).
MPI3501.zip (15.3 KB)
All files from goodtft/LCD-show

[nadirfly]

ok… thankyou! i’ll try

[Edrian_Lois_Villanue]

Hi mate! How do i execute this on command shell? After transfer this, file to /home/volumio via filezilla?

[VictorDUA]

Unzip first. Then copy LCD folder and:

cd LCD
sudo ./install.sh

Most likely you can use the waveshare35a overlay.
The tft35 has very bad performance (5fps)

cd~
wget https://files.waveshare.com/upload/1/1e/Waveshare35a.zip
miniunzip Waveshare35a.zip
mv /home/volumio/waveshare35a.dtbo /boot/overlay/waveshare35a.dtbo

nano /boot/userconfig.txt
dtoverlay=waveshare35a:rotate=90,speed=41000000,fps=50

Public Alpha Test: Audio Without Compromise - Volumio on Bookworm Begins

The Legend of TFT the Stubborn Screen Deep in the heart of the Developer’s Lab, there existed a screen unlike any other. It was TFT35A, a rebellious 3.5-inch trickster with a resolution of 480x320 pixels—small in size but monumental in attitude. TFT had one mission in life: to frustrate, baffle, and occasionally humor those who dared to configure it. It had watched other screens boot up smoothly, flaunting their splash logos and crisp animations. But not TFT. No, TFT had higher standards for c…

Touch Display and Peppy Meter Basic working just fine. That’s enough for me.

@Wheaten

No. I can not. The color depth and resolution indicate that the driver is not suitable. I better stay on 5 fps.

[Wheaten]

Strange your screenshot is exactly what I had using the TFT35 overlay, hence moved to the Waveshare one.

[VictorDUA]

The wiki says that this is (MPI3501) not a Waveshare display and provides a link to goodtft. Maybe you have a Waveshare. Maybe something in the air…

[Wheaten]

Guess the air it is, for sure not a Waveshare screen.

Perhaps both copies of the same file are required?

waveshare35a-overlay.dtb & waveshare35a.dtbo

tft35a-overlay.dtb & tft35a.dtbo

We have very different screens:

I have install a fresh Volumio 3.378, on my Rasp 3B+ because on that version Tidal works fine
and install Touch Display version 3.5.2 but i have an Error

Removing plugin directory /data/plugins/user_interface/touch_display
An error occurred while installing the plugin Error
Removing temporary directory /tmp/touch_display-S07jIx90DC

[gvolt]

This indicates that not all software packages the plugin requires succeeded to download. Most often either sytem time ist not set correctly or a network issue is the reason for failing downloads.

So at first check and set the date and time on your system. If they are already correct, changing the repository mirror as described here may help.

If you should be using something like pi-hole or special DNS settings in your network, make sure to rule them out as a possible cause, too.

Hi again @gvolt

I have tried 10 different mirrors still with the same result unfortunately…
Time is also set.

Is the really nothing else to do?

Would a reinstall of Volumio on a clean SD work?

Thanks in advance

@miklau

Would a reinstall of Volumio on a clean SD work?

It is at least worth a try. If possible, also try a different SD card.

[miklau]

Thanks @gvolt

Fresh install at a brand new SD card and I was able to install the Touch display plugin.
I have set my HDMI screen settings in the userconfig.txt file in the boot folder and the screen works and with the Volumio logo at startup.
Unfortunately there is no image at the screen once booted into Volumio and this error appears when I try to change any settings:

Any thought please?

My screen is a 8.9" 1920x480 HDMI screen and I am using the following settings:

#Control of 1920x480 8.8" screen
hdmi_timings=480 0 30 30 30 1920 0 6 6 6 0 0 0 60 0 55296000 8
hdmi_group=2
hdmi_mode=87
#hdmi_drive=2
display_rotate=1
hdmi_force_mode=1
hdmi_blanking=1
framebuffer_width=1920
framebuffer_height=480
max_framebuffer_width=1920
max_framebuffer_height=1920

Thanks in advance

What are make and model of the display?

What is your Pi model?
