Displaying two signals using LabVIEW from Arduino board

[maazqaiser]

Thanks for your videos. Yes exactly i want to make a test bench like you but in my case i want to see the voltage and current through the sensors.The Sensors output are given to analog pins of Arduino through where i get the both values at the COM ports. I can show you in my video now the code and working just wait please. As u see my VI already. Thanks for sharing with me the videos.

Thanks

In my case, I didn't use time setting in my lab view, but I let the data displays in LabView due to data sending freq from Arduino by setting millis value (since I wrote the code for rotation sensor). 

You may take a look at mine here:

As Master @RavensFan suggested,  you need to use string to set the output data from Arduino. You may take a look at our discussion above. The code in Arduino can you see in one of my video above. And you may use a match pattern in LabView Block Diagram for parting the data.

Videos are not really helpful.  It is shaky, hard to read, and quick distracting.  Just post the code so we can analyze what we need to.

Please check the files i have upload it. 

Where can i find this Scan from string to break message into two values. I upload all the files which i have. 

Thanks

Can you adjust my VI. I upload it in thread please. I really donot know much about the match pattern.

Please

Thanks

In your Arduino code,   do a single

Println(voltage&","&current)

In LabVIEW, it will look like this:

Is it ok i make a single line now ?

is it fine

and can you tell me where i find that type of string which you put after VISA read block. 

Thanks

PS: I think i m close to my success.

I upload the both picture of VI and the results at COM port of Arduino as u said me. 

I get this error which is in PNG.

Thanks

That is because you are not meeting the format being sent.  Change the format string to be "V:%fV I:%fA".  Of course, I am assuming you used a space in between your values and not a tab.
