Waveshare 3.5inch LCD RPI (B) rev2.0 on RPI3B+ for Volumio

Hi,

I tried for days to install a Waveshare 3.5inch RPI LCD (B) rev2.0 on a RPI3B+, now with success.
Don´t find any guide here nor the web to install and set this hardware. So, as an absolutely Linux noob,
I wrote a script, don´t know if all commands in it are needed, but it works for me, hope it helps anyone.
Please report if I have to change anything.

ws-35b-v2.sh

Complete Volumio + RPI3B+ + Waveshare 3.5inch RPI LCD (B) Rev2.0 installation guide:

  1. Download (sorry no links because of forum newbie restriction max 2 links :roll_eyes:)
  • Volumio image
  • W32 Disk Imager
  • PuTTY SSH
  • ws-35b-v2.sh
  1. Prepare SD-Card:
  • Write Volumio image using W32 Disk Imager,
  • Copy ws-35b-v2.sh on base directory of SD-Card.
  • Put prepared SD into RPI and power it up, headless: wait stop blinking green LED.
  1. Access WEB UI:
  • a) If LAN connection: type volumio.local in web browser. >> Go to step 4.

  • b) If WIFI connection only: take your smartphone, go to WIFI settings, disconnect from actual Network.

  • Connect to "Volumio"s own Hotspot, you are automatically forwarded to Volumios Web Interface.

  • If not, type Volumio initial IP 192.168.211.1 in smartphone web browser, perform Network/WIFI settings.

  • RPI reboots automatically, smartphone loose volumio Network connection, reconnect phone to your home network.

  • Go to modem router, find out and pick up volumios new IP address.

  • Type IP address in Smartphone or PC web browser, in example 192.168.178.32

  1. Prepare LCD Touch
  • with smartphone or PC web browser, go to Volumios WEB UI
  • Go to Settings > Plugins Manager > Miscellanea, install “Touch Display Plugin” it takes about 5 minutes
  • Activate plugin, the display is not working for now.
  1. Run ws-35b-v2.sh script
  • type /dev at th end of volumios address, for LAN: volumio.local/dev, WIFI: in this example 192.160.178.32/dev
  • For SSH rights click on SSH “ENABLE” button, nothing happens but you have already SSH
  • Run PuTTY, login as: volumio, password: volumio. Type (or copy and right click in PuTTY window) following command:

sudo sh /boot/ws-35b-v2.sh,

  • password: volumio

If succes, RPI is rebooting itself, after reboot the display is now working, enjoy.

Yves.

Thanks for this,
This guide might work also with rpi4?
Thanks

Hi Lintbf,
can´t say because I don´t have RPI4 for testing it.
But I think it´s the same install procedure.
Do You want to try it out and report here?
Greetings.

I will be glad to do so but I do not have a lcd…
Thanks

The guide from waveshare is quite complete…
https://www.waveshare.com/wiki/3.5inch_RPi_LCD_(B)
Anyway nice work. It works with Pi4 like a charm…
I have the same screen and did another project…

Hi noiro, thanks for testing it on RPI4

I know this site but waveshare only offers 2 installation methods,

  • first, to run LCD35B-show-V2 script that is killing your volumio installation,
    I tried it a few time,
  • second, a 7.9 Gig. ready-to-use-image.

calibration.conf file from waveshare git hub, especially for 3.5 B V2,
needs a little modification that works for volumio, userconfig.txt too,
no indication of this on this website, quite frustrating for a beginner like me.

Nice projects, want get a closer look…

Hi!
ws-35b-v2.sh is not avalible now (
Can U make a new link please?
Thank you!

Hi, sorry,

here it is >> ws-35b-v2.sh <<

I tried to get my Waveshare display running but unfortunately it doesn’t…
Don’t know why.

In case you are not just reporting but looking for help, some more details would be required :wink:

  1. What Pi model are you using?
  2. What is the exact model name of the screen?
  3. What steps have been taken in detail in order to install the screen (hardware connections and software installation)?
  4. Is the display lit or at least its backlight?

Also connect to Volumio via SSH and post the results of

cat /boot/config.txt

cat /boot/userconfig.txt
and
systemctl status -l volumio-kiosk.service

Hi,

More or less Igave up😊
But I will sent you the information this weekend.

It’s a 4’’ wave screen. Raspi 3b+, latest volimio image.
Already tried it a dozen time, all kinds of scripts, internet manuals. But maybe you can help.
The sreen is lit. Yes sometimes I see Volumio shattered.

Will be back,
Ad.

I started all over again and did exacty the steps from your topic.
Latest Volumio image, lit is on.
thers is something on the screen but shattered.

Looks strange, but could be wrong overlay here:

I would need the exact model name of the screen please.

Additionally please post the result of

chromium-browser version

From your picture the screen looks like a Waveshare 4inch HDMI LCD.

If that should be correct remove

dtoverlay=waveshare35b-v2-overlay

from “/boot/userconfig.txt” but add the following lines:

hdmi_group=2
hdmi_mode=1
hdmi_mode=87
hdmi_timings=480 0 40 10 80 800 0 13 3 32 0 0 0 60 0 32000000 3

dtparam=swapxy=0
dtparam=pmax=255
dtparam=xohms=150
dtparam=xmin=200
dtparam=xmax=3900
dtparam=ymin=200
dtparam=ymax=3900

Edit “/etc/X11/xorg.conf.d/99-calibration.conf”:

sudo nano /etc/X11/xorg.conf.d/99-calibration.conf

Substitute its content with

Section "InputClass"
        Identifier      "calibration"
        MatchProduct    "ADS7846 Touchscreen"
        Option  "Calibration"   "172 3950 3871 194"
        Option  "SwapAxes"      "0"
EndSection

Save the file with Ctrl+x, y and Enter.

Reboot.

The steps above will have no impact on your second issue that the UI is not shown. So after rebooting you will only see the command line login again.

After we have managed the UI to start you need to check if touch is misaligned to the (visual) display. If so “99-calibration.conf” will need changes.

Thanks, yes it is working.
I almost got this myself but I made a typo somewhere.

I have the command line, how do I get Volumio starting ?
Is this somewhere discussed?

Many, many thanks!!

Please post the result of

That’s what I suspected: chromium has not been installed (properly). Easiest to try would be uninstalling the touch display plugin and re-installing it. You might watch the installing process for errors in a terminal with

journalctl -f --no-tail

Installing respectively downloading chromium fails from time to time for various reasons. One reason could be too less space on your SD card. After setting up Volumio did you wait so the file system could expand?

If that should not have been the case and disk space should be too low you could create a file “boot/resize-volumio-datapart” with

touch /boot/resize-volumio-datapart

and reboot before re-installing the plugin. Then the data partition will get expanded to its maximum size.

Before re-installing I did touch /boot/resize-volumio-datapart
Now reinstall.

Also saw short: error connecting XserverScreen Shot 05-14-21 at 08.01 PM

Did you reboot after that and before re-installing?

Did you watch the log during re-installing?
