How to read map file ?

[krishna_ak]

Hi,

   I have a linker map file having some data like below

   File name :Load.map

     2000b598   ABC

     20009672   bbb

  My requirement is to read  hex value when  an input is given.

  Inuts are "ABC" or "bbb" .

  Example: when input "bbb" is given then 20009672 needs to be displayed in  indicator.

  please let me know the solution as this is very urgent.

Thanks in advance,

krishna

Read the file into an array, index out column 2, do a Search 1D Array for the input value, use the index of the found value to get the value in column 1.

Hi,

   Nice to see your reply. The thing is there is no provision to read *.map file using File operations. So how to read *.map file ?.

There's no provision to read any specific file extension beyond the NI files such as lvm. Your original post specified a data format and I got the impression it was a text file. It's it's not really that, you will have to do some extra work.

Use the Read from Text File or Read From Binary File. If it's binary, you will have to know the format. If this .map file is something you created, you already have the information.

In my orginal post I mentioned as linker file and file name too. nyways sorry to say this I didn't understood below line

"If this .map file is something you created, you already have the information."

I hope you understood my question. If no please let me know I'll try to give more clarity.

Thanks,

Yeah, missed the fact that it was a linker file.

What generated the .map file? The only .map files on my system are xml. What does yours look like when you open it with notepad?

[krishna_ak]

:-).

Linker file generated by Multi.

Assuming my linker file having the following data

File name : Load_3.0.map

2000b598    Switch1
2000b590    Switch2

Now I want to read Switch2 address. When I read using match pattern I got the output as

 2000b598    Switch1

 2000b590

But I am expecting output as  2000b590.

Please find the attached vi and map file for your reference. I know I need to work around something but I'm snot sure what need to be done.

Please modify Load_3.0.txt to "Load_3.0.map" due to an attachment error.

Awaiting for your positive reply.

It's just a tab-delimited text file. The .map extension is irrelevant. Just do what Dennis said in his initial reply. You can use Read From Spreadsheet File to read in the file.

I am sorry to ask you that can you modify the attached vi  and reply please ?.

This is really basic stuff - both with LabVIEW and file reads/array manipulation in general. check into the tutorials.
