Opal Kelly does not officially support LabVIEW for FrontPanel, but I hope someone cam offer some suggestions.
Running under Windows XP, I have an XEM3010-1500P attached via USB, and can successfully configure and control it from the FrontPanel GUI.
From LabVIEW (2010), I started with Counter.vi from the LABVIEW samples.
That failed, without much in the way of information.
Since it was written for an older API revision, I decided to import the libraries and incrementally build a simple VI, paralleling its calls.
I followed the import steps in the 12-28-2010 Forum postings, LabView FrontPanel DLL Import and all the okFrontPanel User Library Vis imported, apparently with no problems, but I have not gotten even a very simple initialization VI working.
Construct.vi returns a handle, apparently time based, differing with each call
Open By Serial.vi returns a decimal string, equal to FFFF FFFF (-1, Int32), and the same handle out as was passed in, regardless of the device number string passed to it (0, 1, 2, 1IW [sticker on the module], etc.).
Get Device Major Version.vi returns -1, as does Get Device Minor Version.vi
It appears that Open By Serial is failing, but I don?t have a clue as to why!
I would be very grateful for any help!
