LINX 3.0 on the Raspberry Pi 2, 3 and 4 running Raspbian Buster

[AndyLB]

Hi everyone,
LINX can be installed on the Raspberry Pi 4.  The LINX 3.0 Target Manual Install Process (https://www.labviewmakerhub.com/doku.php?id=learn:libraries:linx:misc:target-manual-install) did not work due to changes in the latest version of Raspbian. 

Here is the procedure that I used to install LINX. The procedure also works on the Raspberry Pi 2B, Pi 3A+, Pi 3B and Pi 3B+ running Raspbian Buster.

1. Setup the Raspberry Pi using a new installation of Raspbian Buster. 
2. Change the default password for the Pi account on the Raspberry Pi.
3. Setup a WiFi or Ethernet connection from the Raspberry Pi to your router.
4. Enable SSH on the Raspberry Pi.
5. SSH into the Raspberry Pi or open a terminal window on the Raspberry Pi desktop.
6. Check that the Raspberry Pi can access the Internet by entering the command

ping -c 4 raspberrypi.org

7. Enter the commands shown in the code block below.
Note: The text may wrap due to the web browser window size. I recommend copying the text into a text editor to see the original formatting. 

# Enable i2c and spi
sudo raspi-config nonint do_i2c 0
sudo raspi-config nonint do_spi 0
# Update Raspbian
sudo apt-get update
sudo apt-get dist-upgrade -y
# Add the LINX repository
sudo sh -c 'echo "deb [trusted=yes] http://feeds.labviewmakerhub.com/debian/ binary/" >> /etc/apt/sources.list'
sudo apt-get update
# Install the LINX package. Error messages will be displayed for the
# nisysserver.service and labview.service
sudo apt-get install -y lvrt-schroot
# Move the nisysserver.service and labview.service files to the systemctl folder
sudo mv /etc/systemd/system/multi-user.target.wants/nisysserver.service /lib/systemd/system
sudo mv /etc/systemd/system/multi-user.target.wants/labview.service /lib/systemd/system
# link liblinxdevice.so to the Raspberry PI device driver file liblinxdevice_rpi2.so
sudo schroot -c labview -d /usr/lib -- ln -s liblinxdevice_rpi2.so liblinxdevice.so
# Enable the nisysserver.service and labview.service to start on boot
sudo systemctl enable nisysserver.service
sudo systemctl enable labview.service
# Start the nisysserver.service and labview.service
sudo systemctl start nisysserver.service
sudo systemctl start labview.service

You should now be able to connect to the Raspberry Pi from the LabVIEW Project Explorer.

Cheers,
Andy.

Thanks for posting this - but I've followed it exactly and can't get past the line:

sudo sh -c 'echo "deb http://feeds.labviewmakerhub.com/debian/ binary/" >> /etc/apt/sources.list'

When I run the next line to search the list it keeps coming up with the error:

"Malformed entry 4 in list file /etc/apt/sources.list ([option] unparseable)"

"The list of sources could not be read"

Is there a workaround for this? I'm using a Raspberry Pi 3B with the latest Buster OS.

Thanks

This is great information could you post it on the LabVIEW Makershub LINX forum too.

Target Configuration wizard NEVER worked for me and always returns the error "The unknown is not a supported device" on a R-pi 2,3,and 4 

I have only ever been able to use LINX on an Arduino

Hi Ross,

Thank you for running the installation procedure.
The command you mentioned was from the Makerhub LINX 3.0 Target Manual Install Process.

Have you already tried it on this installation of the OS? 

I had to change the command slightly for Raspbian Buster. It is 

sudo sh -c 'echo "deb [trusted=yes] http://feeds.labviewmakerhub.com/debian/ binary/" >> /etc/apt/sources.list'

I recommend that you start from a new installation of Raspbian Buster on the Raspberry Pi.

Here is a log of the LINX install on the Raspberry Pi 3B and the contents of the /etc/apt/sources.list file.

Hope this helps to get LINX running on your Raspberry Pi.
Thanks,

Hi RTSLVU,
Thank you for your comments and the Kudos.

I posted the information on the LabVIEW Makerhub LINX forum a few weeks ago. Hopefully it will get approved soon!

Cheers,

Andy.
