Best practices for real-time LabVIEW ↔ Julia data exchange

[fraukenbl]

Hi everyone,

I am currently working on a project where I want to integrate LabVIEW with Julia. The basic idea is that LabVIEW acquires some signals from hardware, Julia processes the data (e.g., simple computations like scaling or filtering), and then LabVIEW receives the results back.

I am considering using TCP/IP Sockets or ZeroMQ since there are toolkits in LabVIEW for it.

Before I commit to building everything on one of these approaches, I wanted to ask the community:

• Are there other practical ways to exchange data between LabVIEW and Julia, especially for real-time or near-real-time applications?
• Any experiences with using shared memory, memory-mapped files, or other IPC mechanisms in this context?
• Any advice on pitfalls or best practices for continuous signal streams between LabVIEW and Julia?

Thanks in advance for any suggestions! Frauke

Why Julia, what is special that LabVIEW cannot achieve or is it very large implementation that investing to bridge LabVIEW and Julia is beneficial compared to reinvent it in LabVIEW?

Since bandwidth, data size and, timing requirements are not mentioned, just use TCP/IP. Its easy to code, easy to debug and there are no external libraries required.

Heck, just write the data to a text file and have Julia write a new one next to it. Even easier to debug than straight TCP/IP!
