Raspberry pi zero w and LCD display 20x4 i2c

I do not speak English fluently. I would like to install the LCD display after the i2c 20x4 rail. Is it possible on raspberry zero w and how to do it?
If there was such a topic, please give some link because I am looking for a few days and every plugin are some complications - none works.

Anyone?

volumio@volumio:~$ sudo apt-get install lcdproc Reading package lists... Done Building dependency tree Reading state information... Done You might want to run 'apt-get -f install' to correct these: The following packages have unmet dependencies: lcdproc : Depends: libconfig-model-lcdproc-perl (>= 2.042-2) but it is not going to be installed Depends: libconfig-model-perl (>= 2.059) but it is not going to be installed Recommends: lcdproc-extra-drivers but it is not going to be installed libpam-systemd : Depends: systemd (= 215-17+deb8u8) but it is not going to be installed radiod : Depends: python-mpd but it is not going to be installed systemd-sysv : Depends: systemd (= 215-17+deb8u7) but it is not going to be installed PreDepends: systemd but it is not going to be installed E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
I have no idea how to bite it

Hi dj_e,

Try the PydPiper or the hd44780 plugin.
Just do a google search for “volumio pydpiper” or “volumio hd44780”.

ok
I have installed volumio again and updated it.
I uploaded the plugin and launched it.

When you start voumio, this effect:

When you turn on play such:

The i2c line test showed address 3F:

volumio@volumio:~$ sudo i2cdetect -y 1 0 1 2 3 4 5 6 7 8 9 a b c d e f 00: -- -- -- -- -- -- -- -- -- -- -- -- -- 10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 3f 40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 70: -- -- -- -- -- -- -- --

Anyone?
I can’t interpret it. On the one hand, he gets the result that the display is addressed correctly, on the other hand, no communication.
I don’t know how well the I2C line works and whether this operation is correct.

So at least I know that initiation is missing.
Someone something?

I disabled the plugin in Volumio and run the pydPiper service in a docker container.
Instructions can be found here: github.com/dhrone/pydPiper

Runs (almost) out of the box…just run the install_docker.sh followed by install_volumio.sh

sorry, but I’m not fluent in the Linux world.
That’s why it takes me so long to run it. Sorry, but the tutorial she sent is not complete.
In point 2 it is written to edit the service - unfortunately it is not written and it causes me a problem. Thanks for the help.

  1. disable (or uninstall) the pydpiper plugin in Volumio
  2. enable ssh to your volumio player in volumio.local/dev
    (click enable ssh button)
  3. login with ssh to your volumio player: ssh volumio@volumio.local
    username=volumio
    password=volumio
  4. run the following commands:
    git clone https://github.com/dhrone/pydPiper.git
    cd pydPiper
    ./install_docker.sh
    ./install_volumio.sh

follow the instructions on your screen.

Thanks. I may not be an eagle, but I can do something, that’s why I started from point 4. It quickly turned out that you need to uninstall the plugin. I started with the correct installation and it turned out that when running the plugin there were such complications, of course, it was not installed:

[code]UPDATING pydPiper.cfg
Creating pydpiper.service file

cp: not writing through dangling symlink ‘/etc/systemd/system/pydpiper.service’
Failed to execute operation: No such file or directory
Failed to start pydpiper.service: Unit pydpiper.service failed to load: No such file or directory.[/code]

I wonder if it will do with a clean volumio installation.

:frowning:
