I have a problem with the communication between arduino board and Labview.

Somebody can help me?.

I run the simple LED example on arduino for the first time and works very well, but when I stop the program and run it again, my board doesn't run the program, the RX led of the board keep blinking and it stay like that forever, somebody can tell me what it's wrong there?.

Try running a VI which closes a reference to your Arduino resource. I did this often while I was testing, as I would have a similar problem when restarting the program. Another way to do this would be to kill your LabVIEW process and restart the whole thing. Are you getting any errors? Try a high light execution with a few probes on your wires to see if any are spitting out errors. Hope this helps.

Hi peter-R, well I realized that my mistake was to stop the program by using the abort execution button, instead of using the stop button to get out of the while loop and close the connection between arduino and labview. I had not realized. But anyways, I apreciate your help.
