Labview uses Big-Endian format (most significant byte MSB first).
On the PC the format is Little-Endian (LSB first).
In order to read a binary file created by something other than labview
you will need to use the "Swap Bytes" and / or "Swap Words" functions
Found in Functions->Advanced->Data Manipulation.
for the above example LV reads '0100', send to swap bytes
it becomes '0001', now the integer is correct '1'.
For larger datatypes I belie
ve that you must also use the "Swap Words"
Be aware that if you change the data and write it back to a file you must
swap again before the write if another application will read the file.
