How to display each value inside a string on an indicator?

[Bob_Schor · Accepted solution]

Why are you sending your Arduino code, which is text, as a picture?  What if we want to suggest changes -- do you want us to retype your code?  Think, and be considerate!

I see that I misled you (for which I apologize).  The Snippet I sent you for reading data from a VISA Stream assumed that you were using a "Terminated" String (since you configured your VISA that way).  But you clearly are not doing this -- you are just sending data, with no separators and no terminators.

I don't know Arduino code, so I may get some of this wrong, but here are the changes you should make:

• Make a routine called "Send a Line" that takes, as parameters, the values (x, y) that you want to send.
• Have the code do something like the following:
  • Serial.print(x); Serial.print(tab); Serial.print(y); Serial.print(lf);
  • "tab" is the control character for a tab, 0x9, and "lf" is line feed, 0xA.

This handles the "separation" (since "print" seems to give as many characters as its argument requires, so you can't tell where "x" ends and "y" begins without it) and also correctly implements the "Termination" protocol that you are using (by default), telling LabVIEW when Arduino has sent all the data.

It is (almost always) a good idea to give us as much information "up front" as possible, particularly if you don't really know what you are doing.

I apologize that i had some concepts about sending data serially to labview confused so i didn't know exactly what information to provide. 

I tested the changes that you suggested (written in a little different manner) and they worked. I also used the Spreadsheet String to Array function as @RavensFan suggested ,alongside Index Array function to separate the elements and displayed them on indicators.

So my problem is solved now. Thanks to you all for the help, much appreciated.

Hello, @promanaid Now, are you able to display data continuously on dial ? Can you please help us if you get it
