not enough memory

[grivilla]

Trying the LV 7.1 examples

“Cont Acq&Graph Voltage-to File (Binary.vi)”
and the corresponding read binary data VI:

“Graph Acquired Binary Data.vi”

I’ve got the “not enough memory” problem while reading the binary data file.

The binary files are “only” 90MB big, however,  I’m running the examples on a Windows server 2003, double processor Xeon 3GHz PC with 2GB of RAM. I used the read VI to get the wave form and to perform an FFT with the “FFT Spectrum (Mag-Phase).vi.

After some failures to read the whole file (Error: not enough memory) I’ve complemented the “Graph Acquired Binary Data.vi” with the “Request Deallocation” function without success. The FFT vi produces the memory error.

How can I further reduce the memory usage?
Or alternatively
How can I read just a part of the binary data file?

Thank you out there!

You can read part of the file with the functions under "File I/O>Advanced File Functions" (Open File, Seek, Scan From File, etc.).
