Serial VISA Read: read buffer string to table of recorded data values? (First Post)

[ZohaibRamzane]

Yes I have control in my hands but I don't know how to add termination character and how it will affect the data.Give some example to do this and the modification possibility....

What's doing the sending? If it's an arduino, you just use the pntln command. Read the help for it. It automatically append a LF.

No its Texas instruments based microcontroller tm4c... Series.All I have configured the UART and sending an array in while loop that I mentioned above.

You need a different forum if you don't know how to program the micro.

So thank you by adding termination character "\n", it is working right.

Hi I am successful in getting data and display it on waveform chart. But now I want to calculata some parameters like waveform amplitude,DC value,frequency etc. But the vi of signal analysis can not be connected with data that is comming in waveform chart . Tell how can I modify the above vi to calculate parameters?

[Dennis_Knutson]

You've got the point-by-point functions. You've got the chart history array, you can use the build array and a shift register. Experiment with the different options and pick the one you want. Please take some of the LabVIEW tutorials.

I don't know how to cancatenate the time with coming value to generate 2D array.how can I do this? Give me some direction. Which function I should use to calculate time wrt coming value?

I would take a look at the build array function, like Dennis had mentioned. There are several other array functions as well that will probably help you do what you need to do. If you’re not as familiar with a particular function, use Context Help to bring yourself up to speed!
