LabVIEW with Tiva C Series TM4C1294

Hello,

 

I'm trying to interface Tiva C Series TI Launchpad TM4c1294 board with LabVIEW.

I setup the interface using USB, COM6. I also setup the VISA open, close, read and write. 

But, when I run the VI, my read buffer and count displays 0. I'm wondering if there is any communication between LabVIEW and the TI board.

I know the board and the interface is working. I'm able to communicate through C++ IDE. But I'm not sure how to go about doing it from LabVIEW.

I'm able to turn the LED on/off from C++, I'd like to be able to do the same task from LabVIEW. Can anyone give me some directions? Or references?

I came across a similar article:

http://e2e.ti.com/group/launchyourdesign/m/tivaarmmicrocontrollerprojects/665977

But I'm not able to figure out how to do it. Any help would be greatly appreciated.

I have attached my VI. 

Here's the link to the code I'm using:

Thank you,

Hi GKlab,

 

Just out of curiosity are you working on a FIRST robotics project?  Just wondering since they use Launchpad.

 

Anyways, I would suggest that you take a look at all of the examples that come prepackaged with LabVIEW.  You can find them by going to Help>>Find examples in any LabVIEW window.  In particular I would have  you look at the Hardware Input and Output>>Serial>>Simple Serial.VI It gives a pretty good explination and example of how to check connection using the *IDN command.  Good luck!
