Also if you could post or PM me a screenshot of your test code, I might get a better idea of what could be causing the problem.

Its worth noting that I kept the VISA locks in place only to (possibly) support multiple applications trying to access the same VISA resource. I implemented my own locking mechanism using a single element queue as a mutex for locking within a single application instance because the behavior of VISA locks (at the time) was erratic. You might want to try removing the VISA lock/unlock calls from the MB_VISA_Lock library and see if that helps. Another culprit could be the VISA flush in the TX ADU.vi. I have once come across a serial device that didn't like the flush command. Try replacing it with a read all bytes at port.

It should work as long as you have NI VISA working on the cRIO and you are using the correct serial port name. You should be able to use serial ports named with the ASRL#::INSTR format.

Glad to hear that it was useful for your test. Thanks for the feedback!

They did say that maybe Unicode support is coming to LabVIEW. I would give LabVIEW a plus for that.
-
Thanks for bringing this to my attention. Not sure why the dlls and so files were stripped out of the source distribution's always included list. This is now fixed in v3.1.2.1

Thanks Rolf for the thorough analysis. I axed support because cross compiling for 32-bit Linux was another hassle, and I suspect that nobody will ever need it. I also noticed that the produced .so was 3MB which seems to be abnormally large and I don't have time to figure out how to get the size back down to a reasonable 300-500kB.

Done. New error code offset is 515000. I also compiled muParser for cRIO RT Linux. You need to manually copy the .so file to /usr/local/lib/ on the cRIO then run ldconfig. Linux 32-bit support has been axed. There is no 32-bit LabVIEW for linux since 2016 if I'm not mistaken.

I would just post it. You can plaster it with a 0-Clause BSD license and walk away. Zero-Clause BSD – Open Source Initiative That way if someone likes they can just take over development without bothering you. It looks like an interesting project but I have no experience with xControls so I wouldn't be the best person to maintain it.
-
Seems like the 500 000+ range would be a good place for these standard but non-NI certified error codes to go. I will make another release that will be focused on improved error handling/reporting. I can see a few VIs that should be touched up in this regard.
-
1) That is indeed the expected behavior. Variable values must be explicitly specified. Their default value is NaN. Note that you are defining x,y,Z as constants in the above example. 2) I was using 5000 range because this package is not NI Tools Network certified and therefore I have no reserved an error range to target. If there is a better starting number, I am open to suggestions. I would not propagate an error code offset input all the way to the top level though. Best to just pick a range and stick with it. But I do understand that 5000 is commonly used at the top level of user applications.

I have uploaded the new release to vipm.io We are now at release v3.0.0 since this is a breaking change. I also started some documentation: LV-muParser User Guide.pdf

Where do y'all get your (free) artwork for UI elements?

There is also Tango Desktop Project which is public domain. -

I finally got the 32-bit shared object built on Linux. After 3 hours of fiddling I simply re-installed gcc-multilib and it just worked. 😡 I have pushed the changes to github. After testing, this will be v3.0.0 because I expect the static linking to be a breaking change in some instances. The next step is to compile a large list of test cases to confirm that the new operators are behaving as expected under as many corner cases as we can think of.
