Analog Discovery 2, LABVIEW, LINX, Raspberry pi

[Torau]

Hi everyone,

I intended use this example VI to run the analog discovery 2 (AD2) in Labview. It was running well in my laptop but, however, I would like to run these VI on Raspberry pi 4. I have tried to use LINX as a interface but still showing error after deployment. Could anybody give suggestions or showing the best way? Thank you.

Best regards

Hi @Torau,

I apologize for the long delay. Unfortunately, LINX was only tested to work with the Raspberry Pi 3; no work that I am aware of has been done to test it and get LINX working with the Raspberry Pi 4. Similarly, the Analog Discovery 2 VIs, like the ones described in this tutorial here, were done on a Windows machine, so we don't have a lot of resources for getting this working properly on a Raspberry Pi.

Thanks,
JColvin

Hi, the instructions for use on the Pi4 are found here.

However, the Waveforms download link is broken.

It appears to be available here: I guess we use the .deb version? Also isn't the Pi4 64 bit? I guess 32-bit version will still work?

Hi @JeremySCook,

Those instructions for the Pi4 are just for WaveForms, not LabVIEW.

The link does still work correctly, but it looks like it was missing the last forward slash at the end, which then correctly re-directs to the https site: https://store.digilentinc.com/waveforms-download-only/

You will want to use the 32 bit debian version yes. The official OS for Raspberry Pi 4 is 32-bit, though I know there are some 64-bit OS's available, so there are some 64-bit versions available in the WaveForms beta downloads: https://forum.digilentinc.com/topic/8908-waveforms-beta-download/. I will see about making the download options more clear about which version is correct since the download page was updated and had some verbage changes but the tutorials were not changed to reflect this.

Thanks,
JColvin

Looks like I posted in the wrong place, but thanks for answering my question!

Sounds good, thanks - that points me in the right direction.

Hi JColvin,

Perhaps you can answer this for me as well: What is the hole pattern for the BNC adapter found here?

Also, what kind of standoffs are you using? Screws/pitch would be especially helpful.

Thanks!

Hi @JeremySCook,

I don't know which specific hold pattern you are referring to, but I'll point you to the mechanical drawing that we have available on the BNC Adapter Resource Center, ,https://reference.digilentinc.com/reference/instrumentation/bnc-adapter-board/start on the right hand side side under Documentation. As for the standoffs and screws this is what I found:

- Machine screw, 6-32 x 0.250
- Standoff, Hex, 8mm x 6-32 

Let me know if you have any other questions.

Thanks,
JColvin

The holes for the standoff screws. That answers my question.

Thanks so much! ?
