Volumio 3.5 inch display (Quimat 3,5’’ Zoll) cannot be installed

S-Informatik · November 16, 2020, 2:06pm

Hello dear community,

I’m new to the forum and have a problem with Volumio. I got it to work on my Rpi3b + and tried to install the drivers for my 3.5 inch display using SSH.

According to the manufacturer’s instructions, I should do the following:

sudo rm -rf LCD-show
git clone https://github.com/goodtft/LCD-show.git
chmod -R 755 LCD-show
cd LCD-show
sudo ./LCD35-show

But when I try to do this, the following errors appear:

volumio@netzwerkplayer:~$ sudo rm -rf LCD-show
volumio@netzwerkplayer:~$ git clone https://github.com/goodtft/LCD-show.git

Since the reboot, my Volumio image doesn’t want to boot either. I tried several options, websites and Google, but got no further. I am really desperate.

One more note: I downloaded and activated the plug-in for the Volumio touch display first!

It would be extremely nice if someone could help me.

Greetings Leon

Hi @S-Informatik,

what is the brand and exact model name of the display?

Flash the Volumio image again. Then don’t run the LCD-show script. We can do the necessary steps one by one.

S-Informatik · November 16, 2020, 7:48pm

Thank you @gvolt ,

Quimat 3,5’’ Zoll

I uploaded a picture, maybe that will help too.

love greetings leon

gvolt · November 16, 2020, 8:39pm

Thanks for the info

Please flash a fresh Volumio image if not already done.

After Volumio has started and settled down open /boot/userconfig.txt, add

dtparam=spi=on
dtoverlay=tft35a:rotate=90

and save the file.

Reboot.

Then install the Touch Display plugin and enable it. Report back if the display and possibly touch already work.

S-Informatik · November 16, 2020, 9:14pm

I did it exactly according to your instructions but unfortunately no success. The display shines black with background lighting. I restarted it after activating the plugin, but now it stays white. However, Volumio continues to boot.

LG Leon🙂
thank you for your help

gvolt · November 16, 2020, 9:24pm

What Volumio version did you flash?

Did you see any error messages after enabling the plugin?

Please post the results of

cat /boot/config.txt

cat /boot/userconfig.txt

cat /usr/share/X11/xorg.conf.d/99-fbturbo.conf

ls -al /dev/fb*

and

systemctl status -l volumio-kiosk.service

S-Informatik · November 16, 2020, 9:56pm

The version is the volumio-2.834-2020-09-24-pi.

As far as I could see, there were no errors installing the plugin.

Thanks for your Help @gvolt

I forgot to mention it in post #3: You need to download “tft35a-overlay.dtb” and copy it to “/boot/overlays/tft35a.dtbo”, e.g. (if you downloaded to Volumio’s home directory) with

sudo cp ~/tft35a-overlay.dtb /boot/overlays/tft35a.dtbo

Did you do that or is “tft35a.dtbo” possibly missing?

S-Informatik · November 16, 2020, 10:31pm

In fact, I was missing the file. After all, the display is black and glowing within a few seconds after starting the Pi. But there is still no logo or font displayed.

Thanks for your many tips

gvolt · November 16, 2020, 10:33pm

Ok, please repeat

ls -al /dev/fb*

gvolt · November 16, 2020, 10:37pm

Open “/usr/share/X11/xorg.conf.d/99-fbturbo.conf” and try changing the line

Option "fbdev" "/dev/fb0"

to

Option "fbdev" "/dev/fb1"

Then reboot.

S-Informatik · November 16, 2020, 10:50pm

Thank you very much, it is actually working now.

Only the touchscreen is not properly calibrated, are there any possibilities?

LG Leon

gvolt · November 16, 2020, 10:55pm

Create (or edit) “99-calibration.conf” in “/etc/X11/xorg.conf.d/” so it has the following content:

Section "InputClass"
        Identifier      "calibration"
        MatchProduct    "ADS7846 Touchscreen"
        Option  "Calibration"   "268 3880 227 3936"
        Option  "SwapAxes"      "0"
EndSection

Reboot.

S-Informatik · November 16, 2020, 11:03pm

I think the top and bottom are swapped with left and right.

Thanks for all of your help, you know that really well.

gvolt · November 16, 2020, 11:07pm

I hope I got it right what is swapped

Try changing “99-calibration.conf” to

Section "InputClass"
        Identifier      "calibration"
        MatchProduct    "ADS7846 Touchscreen"
        Option  "Calibration"   "3700 115 155 3865"
        Option  "SwapAxes"      "1"
EndSection

S-Informatik · November 16, 2020, 11:17pm

Somehow the values are still wrong.

When I press top left, the pointer is bottom left.

If I press the top right, the pointer is at the top left.

If I press the bottom right, the pointer is at the top right.

If I press lower left, the pointer is lower right.

gvolt · November 16, 2020, 11:32pm

I am little tired, so I may be wrong, but I think you need to revert to the values from post #13 except for “SwapAxes” which would remain “1”.

S-Informatik · November 17, 2020, 11:16pm

Hey @gvolt ,

I tried different values myself, but without real success. It seems like the X and Y axes of the touchscreen are reversed.

LG Leon

gvolt · November 17, 2020, 11:19pm

Could you describe how the touch screen reacts (like in post #16) when you use the values from post #13 and set “SwapAxes” to “1”?

You may try adding

Option "InvertY" "true"
Option "InvertX" "true"

to “99-calibration.conf”.
