Oct 03, 2014  In today’s tutorial, I will explain in detail How to get continuous data from COM Port in LabView software. LabView is a very handy tool for the engineers. One can easily plot graphs and can work on different hardware modules with it. One of the best feature of LabView is its extensive help desk. Using LabVIEW to Send Commands via RS232 to ADR Interfaces: LM335 Temperature Measurement. The following application demonstrates how LabVIEW can be used with ADR interfaces, or any ASCII based serial data acquisition and control interface.

Q: How to use the Virtual COM Ports in LabVIEW? A: Follow the procedure described below: Step 1: Run VxComm Utility program to configure Virtual COM Ports of your device (e.g. PPDS-755D-MTCP), refer to user’s manual of the VxComm Driver for the detailed information.

LabVIEW Serial Program Using NI-VISA NI-VISA provides built in serial examples to assist users with application design and development. Serial examples for LabVIEW can be found the in LabVIEW Example Finder by navigating to Help Find Examples Hardware Input and Output Serial. It then performs a serial port read, a serial port write, or both based on the options (read or write) that the user selects on the front panel. If both are selected, the VI will first write data, then read data, and finally close the VISA session that is opened to the port. Dec 18, 2017  If a read is performed, this VI will wait until the specified number of bytes is received at the port. Only the number of bytes specified will be read. For more Serial examples please see the related resources or the LabVIEW Example Finder. To navigate to the LabVIEW example finder open LabVIEW and select HelpFind Examples.

Hello ,

I am simply trying to read serial data in the form of string and simply writing again in the form of string. Their is serial write data into string function but not for reading. How can I convert data into string. I have tried something by my own of which I am attaching the screenshot. Please guide me further.

Thanks

Hello Vikas,

You should use convert byte array to string. to convert the data to string. But wait for serial data & read it as it receives.

Beware of memory management technique else u will ran out of memory.

Thanks for your reply . but as you can see in the screenshot I have already used byte array to string converter and I am simply taking analog data from pin A0 but in the output serial monitor I am just getting some random numbers which is positively not the reading of the sensor which is connected. Even if I try to take the digital reading as true or false and changing it into 0 or 1 using comparison function 'select' and converting it into string I am getting again random numbers.

Hello Vikas

Just me your VI i'll test it here & reply on that

Regards

Here is the vi..

from the serial monitor for getting analog data we need to send 'Get_A00' similarly A02,A03.. so on for other pins.. and for digital 'Get_D02' , D03,D04..D13

I am able to receive and send data through serial. But when I am getting correct data then why program runs default case always in the case structure.

I'm not sure how to best help you remotely as this will requires some debugging. I would start the debugging processing by trying to understand what the read VI is outputting from the serial communication. Maybe you will need to tweak some parameters based on what you are getting.

can i get the arduino code for receiving string data from labview. ?

i have completed labview part for writing string data on com port. but failed to receive it on arduino serial monitor
