Hello

I trying to circular buffer for csv file.

but I can't imaging structure.

2D array, it must be saved to 1D for each in CSV file.

for WHIlE loop repeation speed, leaving to only one 1D array, others must be deleted

 

CSV file should be nesting 1D array.

 

How can I make ?

Your image didn't show how the file is being saved.

Please attach your entire code.

I realize that English is not your native language, but from your Post, I don't know what you are trying to do.  Here are two suggestions:

  • Reply using your native language (we can ask a Search Engine or AI to translate it for us).  Tell us as clearly as you can what you are trying to do.  Don't tell us "how" you want to do it (so don't mention "circular buffers", but let us figure out "how" to accomplish your task).
  • Tell us as much as you can about the background of the Project (in English or your native language).  Try to answer these questions:
    • What are the "inputs" -- describe the structure and nature of the "data" you are processing.  If it comes from data the program is acquiring, tell us such things as how many channels, what data rate, how it is stored, etc.
    • What are the "outputs" -- what happens when the program is finished?  Are new files created from the input data?  Describe the processing, including the format of the output.

You might also tell us about your LabVIEW environment, including your experience with using LabVIEW.  What version(s) of LabVIEW have you used?  For how many days, or weeks, or months, or years have you been using LabVIEW?

 

As the top two suggestions explain, we need to understand the "problem" better.  What is the nature of the data you are processing?  What are you trying to do with these data?

In the block diagram…

 

Did you notice those Training resources offered at the top of the LabVIEW board?

Technically in the Structures pallet, but as i like quick-drop i'd say Ctrl+space, type 'whi' and click on the While loop.
