Visa read error

Hello,

 

I am trying to create a simple serial communication between labview and an Arduino board using its USB interface. The communication works when I use the serial monitor of the Arduino IDE. I used VISA read/write functions to implement it in Labview. The writing seems to work but I get an error -1073807339 during the reading operation. I double checked the baud rate and the ending character. I have no idea what could cause this error.

 

Thanks,

Thomas

Instead of using the Auto Detect Arduino VI, have you tried to open the visa connection with the VISA Configure Serial Port? It is in the Instrumentation -> Serial

I have tried the VISA Configuration Serial Port but the result is the same.
