Volumio with 3.5" TFT Touch Screen (GPIO) RPi 3B+

jurkodj · June 14, 2022, 9:04am

My bad, I made a mistake while checking my aliexpress orders, sorry for that. After dismounting my player today I found display is different. It should be MPI3501 - 3.5inch RPi Display - LCD wiki.

gvolt · June 14, 2022, 11:04am

To adapt the configuration as it should exist after you already performed the steps from post 324 for the MPI3501:

Remove

config_hdmi_boost=7
hdmi_group=2
hdmi_mode=87
hdmi_drive=2
hdmi_cvt 480 320 60 6 0 0 0
dtoverlay=ads7846
dtparam=cs=1
dtparam=penirq=25
dtparam=penirq_pull=2
dtparam=speed=50000
dtparam=swapxy=0
dtparam=pmax=255
dtparam=xohms=150
dtparam=xmin=200
dtparam=xmax=3900
dtparam=ymin=200
dtparam=ymax=3900

from your “/boot/userconfig.txt” and instead add

dtoverlay=tft35a

Execute

sudo curl -L https://github.com/goodtft/LCD-show/raw/master/usr/tft35a-overlay.dtb -o /boot/overlays/tft35a.dtbo

sudo curl -L https://raw.githubusercontent.com/goodtft/LCD-show/master/usr/99-calibration.conf-35-90 -o /etc/X11/xorg.conf.d/99-calibration.conf

sudo curl -L https://raw.githubusercontent.com/goodtft/LCD-show/master/usr/99-fbturbo.conf -o /usr/share/X11/xorg.conf.d/99-fbturbo.conf

Reboot.

THANK YOU! I just needed to add :rotate=270 and it works like charm

AssFit · September 6, 2022, 3:33am

Thanks I did read all post from Nov 2019, get tips to work with my 3.5TFT Inland. I can’t remember how I make it work now because I also following some guides from the other. How to disable the display power saving mode?
edit: screen saver setting can be touch from plug in. Thanks

gvolt · September 6, 2022, 6:24am

If I understand your edit comment correctly, you have already found the solution, so just in case:

The screensaver can be switched off by setting the value “Screensaver Timeout” to 0 on the configuration page of the touch display plugin.

Hi All

So i have this 2.8" tft spi that i dug out from my bits and bobs box, forgot i even had it.

I got a rasp 4B with a fresh copy of volumio installed with the touch screen plugin installed.

I’m just having issues with it switching on and not sure if my connections are correct, i have followed the instructions on here just to try and get me started.

i followed the connections from here, guessing it must be the same tft:

Add a cheap ILI9341 LCD to your balena Raspberry Pi project

Power (Vcc 3.3V)| PIN1|
Ground (GND) PIN|6|
Chip Select (CS) PIN|24|
Reset (RST) PIN|13|
Command /Data (CD) PIN|15|
SPI MOSI PIN|19|
Clock (CLK)| PIN 23|
Backlight (LED) PIN|11|

i assume its ok? not sure this would allow touch function but cant seem to find any more info on how this particular tft connects up with touch function.

i found this post with gvolt helping, maybe this will help?

Ili9341 2.8 tft - Help and Support - Volumio

thanks all

gvolt · October 6, 2022, 10:56am

The connection scheme you posted looks ok IMHO.

IIRC there have been versions with (MSP2807) and without (MSP2806) touch screen. From your picture of the circuit board I would guess your display has a touch screen. So in principle touch function should be possible but would probably require additional connections between display and PI.

I would say: Try it

Before executing step 6 of the instructions additionally run

sudo apt-get -y install xserver-xorg-video-fbturbo

Rue · February 1, 2023, 10:20am

hello, i need help installing a 3.5 inch display.

Raspberry pi 3b+ volume 3
i have already tried all possible variants the result is always the same:
touch display error when connecting to the Xserver

gvolt · February 1, 2023, 10:26am

Please reveal brand and exact model name of the display.

Rue · February 1, 2023, 10:28am

my display

gvolt · February 1, 2023, 10:43am

Since I don’t know in what state your Volumio installation is now, I recommend to start with a fresh Volumio system, i.e. start from scratch.

Install the Touch Display plugin.
Execute

sudo apt-get -y install xserver-xorg-video-fbturbo

sudo apt-get -y install xserver-xorg-input-evdev

sudo cp /usr/share/X11/xorg.conf.d/10-evdev.conf /usr/share/X11/xorg.conf.d/45-evdev.conf

sudo curl -L https://github.com/goodtft/LCD-show/raw/master/usr/mhs35-overlay.dtb -o /boot/overlays/mhs35.dtbo

sudo curl -L https://raw.githubusercontent.com/goodtft/LCD-show/master/usr/99-calibration.conf-mhs35-90 -o /etc/X11/xorg.conf.d/99-calibration.conf

sudo curl -L https://raw.githubusercontent.com/goodtft/LCD-show/master/usr/99-fbturbo.conf -o /usr/share/X11/xorg.conf.d/99-fbturbo.conf
```
cat >> /boot/userconfig.txt <<EOL

dtparam=spi=on
dtoverlay=mhs35
EOL
```
Reboot.

Edit: Step 2 contains commands which are not correct for the display shown in Rue’s previous post. However, I’ll leave them here anyway so that the following communication with Rue remains comprehensible.

The correct commands for the display in question are:

sudo apt-get -y install xserver-xorg-video-fbturbo

sudo apt-get -y install xserver-xorg-input-evdev

sudo cp /usr/share/X11/xorg.conf.d/10-evdev.conf /usr/share/X11/xorg.conf.d/45-evdev.conf

sudo curl -L https://github.com/goodtft/LCD-show/raw/master/usr/tft35a-overlay.dtb -o /boot/overlays/tft35a.dtbo

sudo curl -L https://raw.githubusercontent.com/goodtft/LCD-show/master/usr/99-calibration.conf-35-90 -o /etc/X11/xorg.conf.d/99-calibration.conf

sudo curl -L https://raw.githubusercontent.com/goodtft/LCD-show/master/usr/99-fbturbo.conf -o /usr/share/X11/xorg.conf.d/99-fbturbo.conf

cat >> /boot/userconfig.txt <<EOL

dtparam=spi=on
dtoverlay=tft35a
EOL

Rue · February 1, 2023, 10:45am

Thanks I will do that

gvolt · February 1, 2023, 10:50am

Please note that I corrected the overlay in my previous post.

Rue · February 1, 2023, 11:05am

I now only have a white glowing display

gvolt · February 1, 2023, 11:10am

Please post the results of

systemctl status -l volumio-kiosk.service

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

and

cat /var/log/Xorg.0.log

Sorry, my bad. In post #345 I changed the overlay from the initially correct to the wrong type…

Now execute

sudo curl -L https://github.com/goodtft/LCD-show/raw/master/usr/tft35a-overlay.dtb -o /boot/overlays/tft35a.dtbo

sudo curl -L https://raw.githubusercontent.com/goodtft/LCD-show/master/usr/99-calibration.conf-35-90 -o /etc/X11/xorg.conf.d/99-calibration.conf

In “/boot/userconfig.txt” you also have to change

dtoverlay=mhs35

to

dtoverlay=tft35a

Then reboot.

thanks for the quick and uncomplicated help!
where do i enter the change for the rotation of the display

gvolt · February 1, 2023, 12:01pm

For rotating the display by 90 degrees change

dtoverlay=tft35a

to

dtoverlay=tft35a:rotate=90

and reboot.

Note that touch has to be rotated, too. If touch currently is correctly aligned to the display then run

sudo curl -L https://raw.githubusercontent.com/goodtft/LCD-show/master/usr/99-calibration.conf-35-180 -o /etc/X11/xorg.conf.d/99-calibration.conf

to follow a rotation of the display by 90 degrees.

Thanks, everything works
