After several years of trying to get drivers for my Agilent Technologies 82357B USB to GPIB Interface to work with a rPi I Googled up a cook book procedure that works.

The discussion is on the EEVBlog discussing a script on GitHub that is what I used. OK, it kinda worked on an old rPi 3 I had in the cupboard, but could not get the back end stull to load. Tried one final time on a rPi 4 and success! Mind you, I have not tried anything beyond an *IDN but I did get the correct ID back.

Just wanted to share this.

 

That will be a useful addition to the Pi interface capability.
It reminds me of the IEEE-488 (GPIB) interface I implemented on my VIC-20 parallel I/O port in the early 1980s. I wrote the driver on the 6502 4-bit single pass assembler. It was great being able to make automatic measurements at home with my HP 3437A voltmeter.
P.S. I worked for HP for 33 years.

 

KeithWalker: Making GPIB interfaces can be interestingly fun. At one point when I was using Microchip PICs to a great extent I made a serial to GPIB interface dedicating a PIC and the TI interface chips to the task. I too got a voltmeter to cough up it's secret measurements.

The project never went anywhere (neither did the company) but I enjoyed the task.
