Newbie Question: Reading, Converting and Displaying ASCII Hex file data...

[Dundorf]

I have a ASCII Hex file with data formated as shown.  (The real file has hundres of lines)

$00FCBA005C00003F363A352D386E

$00FCB7005900003F393938FE3B7A

$00FCBD005A00003F3B793A853E8A

$00FCBA005A00003F3F383F194195

$00FCC3005B00003F42F74227450A

$00FCF6005D00003F46B644714815

$00FD04005900003F483648424B1C

I need to seperate each line into groups of bytes like this:

$  00  FD04  0059  00003F  4836  4842  4B1C

Then convert each group into decimal and display in charts, gauges, etc.

Any help and/or examples would be appreciated.  Also where can I find more info (and examples) on this process in the Help section of Labview?

Thanks,

Chris

Try the Scan from String function like in the attached. (LV 8.5)  This would be part of a loop after each line is read from the file.

Ravens Fan, With a little tweeking that worked. Thanks for your help. Chris

I am trying to read a binary file that contains hex data. As far as I can tell, the Read From Binary File function does not support a data type specifically to read hex data. I can read it in as a text file but it simply spits out the ASCII junk. Format Into String and Scan From File does not seem to work either. Any suggestions? I am working in LabVIEW 8.0. Thanks in advance.

While fundamentally an ASCII file and a binary file are essentially the same (they're both just a series of bytes), an ASCII file contains characters that can be interpreted as numbers, while a binary file contains pure values. Thus, "hex" values has no meaning, and that's why there's no special hex data type for the Read from Binary File. You read in a set of numbers (integers in your case). They can be 8-bit, 16-bit, 32-bit, or 64-bit, depending on what was written. A number is a number is a number, whether you look at it as decimal, hex, octal, binary, whatever. Thus, you need to read in the binary file as a set (array) of integers and set the display format of your indicator to whatever format you want.

smercurio, Thanks for the Hex, ASCII, binary description. I aprreciate the help. Chris
