Installing/using PyVISA-py on Raspberry Pi up vote 0 down vote favorite I am trying to install PyVISA-py on my Raspberry Pi 3 Model B because I understand that the normal PyVISA needs the NI backend that is not supported on the Pi. Pyvisa has an optional query parameter for list_resources(), which you can use to narrow the scope of your search to just your device.The syntax for this is like a regular expression. PyVISA Documentation, Release 1.10.0.dev0 PyVISA is a Python package that enables you to control all kinds of measurement devices independently of the interface (e.g. GPIB, RS232, USB, Ethernet).

Python 2.7.5, Mac pc OS 10.7.4, PyVISA 1.4, NI-VISA 5.4 If I realize properly, the main cause that PyVISA includes lots of mistakes when imported on a 64-little bit Mac is definitely because PyVISA compiles as 32-bit, while Python will run by default as 64-bit. This needs that the Mac pc user tell Python to operate in 32-little bit, via the command word: defaults compose com.apple.versioner.python Prefer-32-Little bit -bool yes !

(see here, fór example: - there aré MANY online discussións where this soIution is required tó run PyVISA ón the Mác) (This turns óut to be moré difficult for á MacPorts and/ór Spyder python - l still dón't know hów to get PyVlSA usable within Spydér because óf this 32-bit issue). Teen 19yo rate the ride. One eventually finds out that some some other Python component they use was put together as 64-little bit just (not really common), and offers to eventually revert to normal 64-little bit Python - thus PyVISA can be inadvertently mutually exceptional with some some other Python segments on the Macintosh OS. As mentioned as a sidé-note ón this GitHub problem: PyVISA should identify this and compile as 64-bit if necessary. Only now I feel able to start rolling out the adjustments for PyVISA and searching into problems. Sorry for the hold off. It is usually in fact a little little bit more complex because PyVISA does not put together anything. It will be simply a wrapper and it is dependent on the VISA collection you have got downloaded and installed.

As significantly as I know, there is usually no way to call a 32 little bit library from a 64 little bit python. The only way is certainly to operate python in 32 pieces. You can perform it as defined in the hyperlink you have submitted or using a virtualenv. I will create this in the Common questions. Only now I am capable to start moving out the modifications for PyVISA and looking into issues.

Sorry for the delay. It is definitely really a little little bit more complicated because PyVISA does not compile anything. It can be simply a wrapper and it depends on the VISA library you possess downloaded and installed. As considerably as I know, there will be no way to call a 32 bit collection from a 64 bit python. The just way can be to operate python in 32 bits. You can perform it as referred to in the link you have got submitted or making use of a virtualenv.

I will create this in the FAQ.

I authored a information acquisition program/script that works with a device developed by our cooperation. The issue will be that I can only go through from this device. No composing is possible, so it's not really possible to use a serial '?IDN.' order to understand what gadget this can be. The just thing that defines this device will be its 'Design' that can be seen in 'Products and Computer printers' in Handle Screen of Windows. The adhering to figure shows it: The guy who made the gadget was capable to generate a labview basic system that concentrated amounts this name from the gadget through NI-VlSA through something called 'Intf Inst Name', which can be known as 'Interface Information:Interface Explanation'.

If I obtain this model name and compare it with the pyvisa gadget title, I'll become capable to instantly identify the presence of our gadget, which is usually an essential matter to have, in case a USB detachment occurs. This is certainly because VISA starts the gadget through a name that can end up being various on every computer, but this name 'Gps navigation DATA LOGGER' can be the exact same everywhere and always. I require this remedy to be cross-platform.

That'h why I need to use pyvisa or pyseriaI. Though any cróss-platform option is Okay. Therefore my query in brief: How can I make use of pyvisa/pyserial to find the design title corresponding to the device model (in my situation 'Gps navigation Information LOGGER')? Please talk to for any additional information you may need. Update I discovered that there'beds an 'attribute' pyvisa with the name 'VIATTRINTFINSTNAME' that would get this name, but I don't know how to use it. Will anyone know how to go through these characteristics?

I found the method to perform it. Unfortunately it entails starting every VISA device you have got in your personal computer. I published a little pyvisa functionality that will perform the job for you with remarks.
