Requirements: View

This NI LabVIEW example demonstrates how to extract data from an HWS (Hierarchical Waveform Storage) file that contains a single waveform. The data is read in chunks, formatted into a spreadsheet string, and then written to a text file.

NOTE: For this example, the data in the HWS file must be saved as Digital U8 data type. An error will occur if the HWS file contains the U16, U32, or WDT (Waveform Data Type) data types. To make the example support these data types, you need to adjust the two instances of the polymorphic function niHWS Read.vi.

requires additional software
The web page introducing this example code does not indicate that any additional software is required when in fact niHWS software is needed to run it
