Best practices for real-time LabVIEW ↔ Julia data exchange

@Jake

Sigview reportedly can acquire data from NI hardware and can call Julia natively. It is inexpensive with a free trial available.

Intriguing:

• Julia Language embedded scripting for adding new analysis functions or input/output formats

Is this the first commercial software to use Julia as a scripting language (even exclusively seemingly; I do not see e.g. Python listed)?

[I mean there’s more commercial Julia software, like Dyad/JuliaSim (closely tied to JuliaHub), no other that I know of using Julia, from otherwise non-Julia software.]

Am I right in assuming that Sigview can only handle data acquisition in terms of analyzing and plotting measurement data recorded with some kind of DAQ hardware but not able to fully control the DAQ hardware in terms of sending signals out (e.g. to adjust currents through coils, etc.)?

The author of this software @gobrad is in a better position to answer this question.

Some more information is at Embedded Julia scripting in SIGVIEW, request for comments , SIGVIEW - interface with DAQ via JULIA , and @cmtasso may have some knowledge based on Extract rpm from tachometer signal .

Thanks, I contacted @gobrad and he confirmed that Sigview’s focus is lying on analyzing measured data. However, the output part might be handled via the Julia scripting function. Therefore, my first shot will be a combination of Sigview for data visualization and analysis (plus Julia scripts for more complex analysis on the receive side) as well as Julia plus NIDAQ.jl or the Python library nidaqmx (via PyCall.jl) to handle signal output.
