Library for Linux GPIB

Download the source files and extract them. First go to the kernel sources like :

cd /home/stephane/Téléchargements/linux-gpib-kernel-4.3.3/

1 - install packages to compile the kernel file :

sudo apt-get install gcc
sudo apt-get install build-essential

2 - install linux-headers-generic to compile in C:

sudo apt-get install linux-headers-generic
sudo apt-get install autoconf
sudo apt-get install automake
sudo apt-get install libcrypto++-dev

3 - compile:

make all
sudo make install

5 - check Gpib-usb support by typing:

lsmod

6 - install packages to compile the user file :

sudo apt-get install flex
sudo apt-get install bison
sudo apt-get install guile-2.2-dev

7 - modify command links to launch python under /bin

sudo rm python python3 python3M
sudo ln -s python3.X python
sudo ln -s python3.X python3
sudo ln -s python3.X python3m

8 - install python 3.X-dev, pip, pyvisa and pyvisa-py

sudo apt-get install python3.6-dev
sudo apt-get install pip3
pip3 install pyvisa
pip3 install pyvisa-py

9 - Compile the user file :

./bootstrap
./configure
make all
sudo make install
sudo ldconfig
sudo gpib_config --minor0

9bis - edit the Gpib_config file located /usr/local/etc

the existing board-type value must be replaced by Ni_usb_b for NI compatible instrument or agilent_82357a for Keysight instruments or any other compatible string for your interface.

10 - For Specific Interface Keysight 82357 follow the help @: https://gist.github.com/turingbirds/6eb05c9267a6437183a9567700e8581a

Get the firmware : https://linux-gpib.sourceforge.io/doc_html/supported-hardware.html#AGILENT-82357A

and do the following instructions:

sudo cp ./gpib_firmware-2008-08-10/agilent_82357a/measat_releaseX1.8.hex /usr/local/lib/udev/

Insert the command line to enable everyone to access to the GPIB

sudo nano /usr/local/lib/udev/udev....script

chmod 666 /dev/gpib0

Dans le fichier script/bash /usr/local/lib/udev/gpib_udev_fxloader il est spécifié comme répertoire de travail /usr/local/share puis pour le Agilent le répertoire ou doit se situer le firmware est /usr/local/share/usb/agilent_82357a/.

Il faut donc y copier le fichier firmware mesat_releasex1.8.hex

sudo cp ./gpib_firmware-2008-08-10/agilent_82357a/measat_releaseX1.8.hex /usr/local/share/usb/agilent_82357a/

Add specific rules tu udev

Vous trouverez une configuration de rules operationnelle dans le répertoire ./linux-gpib-4.3.3/linux-gpib-user-4.3.3/usb/agilent_82357a qui a le nom 99-agilent_82357a.rules

Copiez le fichier rules dans /etc/udev/rules.d puis redémarrez le service udev

cd ./linux-gpib-4.3.3/linux-gpib-user-4.3.3/usb/agilent_82357a
  sudo cp 99-agilent_82357a.rules /etc/udev/rules.d
  sudo service udev restart

Attention : il faut gérer les droits d'accès aux périphériques dans un premier temps seul le root a accès au /dev/gpib0
