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

reboot now

Connection to 192.168.178.63 closed.
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.
Thank you @gvolt ,
Quimat 3,5’’ Zoll
I uploaded a picture, maybe that will help too.
love greetings leon

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.
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🙂

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

The version is the volumio-2.834-2020-09-24-pi.
As far as I could see, there were no errors installing the plugin.

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?
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

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.
Thank you very much, it is actually working now.
Only the touchscreen is not properly calibrated, are there any possibilities?

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.
I think the top and bottom are swapped with left and right.
Thanks for all of your help, you know that really well.

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

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.

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

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”.
