Read from HEX file error....expecting D(hex) but output A(hex)

[FredFred]

Hello to all....

I am reading a hex file by just using the read from file vi and showing the data on a string indicator. The problem that I am seeing is that when I change the view to hexadecimal, where ever I am expecting a Dhex the read from file vi outputs an Ahex.

I open the file using multiedit and the Dhex is present. Is there a reason why LabVIEW is doing this?

Thanks in advance...

Your attached text file looks like hex 0A 's to me through out.  (which would be the new line character).  I don't see any 0D's (carriage return).

How was this file created?  Are you sure that program was outputting 0D's?

Are you using a raw hex editor to check the file?

When I look at the file I find both characters \0A and \0D in the file. The first few characters as shown in a '\' Codes Display are:

\00\00\00\00\EE\CC\00\00\00\00\00\01\00\00\00\03\07\D8\n\1B\t\f\r\00\00\00\00\00

This was done in LabVIEW. Perhaps you should post your code so that we can see what you are doing that gives you results you do not understand.

All I am doing is using the read from file vi and outputing the string to an indicator. I am not manipulating the data. Just opening up to read the file.

Thanks N advance

I counted 49 0A's, but no 0D's

Thanks for your help....

I attached the following screen shots for my hex viewer and the LabVIEW output.

If you would look at the 23rd hex pair, the hex viewer sees a 0D

but with labview in the same location (23rd pair) the result is a 0A.

I am simply using the read from text file vi and opening the previously posted text file.

Thanks N advance

here's the other file...

First, even though you posted an attachment that has a .jpg extension, it is actually a bitmap.  Please only post .jpg's or preferably .png files to the forum.

Looking at your screenshot, I only see 0A's in it.  Your two screenshots seem to match.

To answer your question about being sure that I output that value...

I used a scope with digital read and validataed that I am outputing a 0D hex....

Thanks for your help
