Continuous Wavelet Transform on a Real Time Target

Hello,

 

I´m trying to perform a continuous wavelet transform on a cRIO real time target. It should be possible, because the advanced signal processing toolkit is supported by LabVIEW RT, but I cannot figure out a way to do it correctly.

 

The problem is that I´m getting an empty output array (CWT coef) from the WA Continuous Wavelet Transform.vi. I have uploaded the required LVASPT_WA.dll to the real time target and changed the calling convention in the "Call Library Function Node" in the SubVIs "WA Continuous Wavelet Transform (Array).vi" and "wa polyphase filter.vi" from stdcall to C (vxWorks operating system), but still get an empty CWT coef array. Everything works fine in a Windows environment with stdcall calling convention turned on.

 

What am I doing wrong here?

 

Greetings
