Nowadays development on pure Assembler is not very popular, because modern compilers can generate “good” code. On the other hand this is a very good exercise, which helps to understand a calling conventions and how it work in very low details.
When calling external code in LabVIEW, we need very often to pass arrays into external DLL. This small “step by step” tutorial walks you through two possible ways of calling C/C++ DLLs manipulating LabVIEW arrays inside.
Calling external code from different languages is great feature of LabVIEW. In general you can wrap almost anything into DLL, then call it by Call Library Function Node. This time we will mix Rust code with LabVIEW.
This is a question, raised again and again on the forums about third-party DLLs: “…whatever I do I cannot get the library to work in LabVIEW. I get the error “The library for this node cannot be found or cannot be loaded….”. Below short “check list” with some explanations.
Two command lines which I often forgot and googling again and again. If you have dynamic link library, but haven’t according *.lib file, then use
dumpbin /EXPORTS yourfile.dll > yourfile.exports
lib /def:yourfile.def /out:yourfile.lib
