Read From I16 File in LV 8.0.1

[jochynator]

I can't find this VI on palette. I used them in 7.1 but in LV 8.0...there isn't.
Strange is that I found it in: c:\Program Files\National Instruments\LabVIEW 8.0\vi.lib\Utility\file.llb.
What am I doing wrong? Why isn't on the palette?


Other thing I am looking for is "error constant" or "error ring" - I'm not sure with the correct name. It was ring with desciption of errors. It wasn't necessary to know the error number, only wire this "error constant".

Thanks all

Just use "read from Binary File" and wire an empty I16 array to the datatype input. 😄

Hi Altenbach,
I already tried, but failed...
Whats wrong?

Thanks again

Read it as a 1D I16 array. LabVIEW has no way of knowing how the rows and columns are arranged, it's just one linear stream of data in the file. You can also get rid of the byte swapping and set the byte order directly.

After reading, reshape the 1D array to a 2D array of desired size. You need to know at least one of the dimension sizes.

I haven't tried, but you might possibly also define the 2D size by wiring a cluster of the row and column numbers to the "count" input. The online help is a bit vague here.

(Check deep inside the old "Read from I16" for an example).

Hi,
I'm still having problems. I know the data file consist of 2columns and 3600rows, but always error occurs.
