because you forgot to edit /usr/local/etc/nf then it's possible that fixing your mistake and trying again will not be enough. Your GPIB card will appear as /dev/gpib0 unless you further modified the nf file. In dmesg you should now see something like: agilent_82350b: HP/Agilent 82350A board found Go ahead and cd into the linux_gpib_firmware/hp_82350a/ directory, then: sudo gpib-config -I. If you have a card that requires firmware then you should look at the README in the relevant directory of the linux_gpib_firmware directory you downloaded earlier. ![]() If you have a card that doesn't require firmware, you can now just run sudo gpib_config. ko) so even for a 82350 A card this will be "agilent_82350b". The board type here will be the same as the kernel module name (without the. You need to use the gpib_config utility to actually initialize your card,įirst we need to modify the config file used by gpib_config.Įdit /usr/local/etc/nf changing the board_type = line to: board_type = "agilent_82350b" gpib: registered agilent_82350b interface You should see something like this in dmesg: gpib: registered agilent_82350b_unaccel interface ![]() Initializing the cardįirst load the kernel module: sudo modprobe agilent_82350b #AGILENT TECHNOLOGIES 82350B PCI GPIB DRIVERS DRIVER#The driver is the same but you need to load the firmware for this card after loading the kernel module (you do not need to load any firmware for the Agilent 82350 B cards). Note that the boards labeled "HP 82350-66501 Rev B" are actually Agilent 82350 A cards. If using an Agilent 8350A card then you should still use the agilent_8350b module. #AGILENT TECHNOLOGIES 82350B PCI GPIB DRIVERS INSTALL#It's probably a good idea to do a quick compile and install of the kernel modules to test things out: cd. #AGILENT TECHNOLOGIES 82350B PCI GPIB DRIVERS CODE#If you have an A card download the latest stable GPIB firmware: sudo apt install gitĮxtracting the source code tar xvzf linux-gpib-4.3.4.tar.gzĬompile and install userland utilities sudo apt install build-essential This version works for newer kernels like 5.8.x as well. ![]() Downloading the source codeĭownload latest stable source code from hereĭon't worry about the "for 3.x.x and 2.6.x kernels" part. #AGILENT TECHNOLOGIES 82350B PCI GPIB DRIVERS DRIVERS#Interestingly it looks like the latest version of the GPIB drivers support GPIB on the Raspberry Pi via bitbanging. Don't buy a "UGPlus" adapter as there is still no Linux support. The slightly more expensive option is the Agilent/Keysight 82357B USB adapter which usually goes for around $80. If you don't have a PCI slot then you can find PCI-E to PCI adapters for around $10 to $15 on ebay or aliexpress by searching for "PCI-E PCI 32bit adapter". I've seen these go for $50 on ebay including shipping. These are A cards despite the "Rev B" in their name. The cheapest way to get a working GPIB adapter might be to find a "HP 82350-66501 Rev B PCI Card". The biggest difference between the A and B models is that the A cards require loading a proprietary firmware (which someone has kindly hosted on github). The project maintaining drivers for various GPIB adapters appears at first glance to be outdated and unmaintained due to being hosted on sourceforge and labeling their latest version as working for "3.x.x and 2.6.x kernels" but don't worry: It is actively maintained and works for 5.8.x kernels. ![]() Even more unfortunate is that neither Ubuntu nor Debian appear to have packages for the kernel modules nor do any third-party apt repos appear to exist that are remotely up to date. Unfortunately the mainline Linux kernel does not have any GPIB support. There are other guides made by other people for a couple of other GPIB adapters here: This is a guide for getting the HP/Agilent 82350 A or B GPIB cards working on Linux. ![]()
