Arduino+ZigBee+LabView

[lolamask]

Hi Everybody.

I need help with my program in LabView. I always got an error when I read the USB port using VISA vi. I am using Arduino to red three analog signals. I need to processed and graph. But I can't because I always have the error reading the port.

I am posting the program code and the pictures of the error.

Please help me! it is my senior project and I don't know how to solve it.

The error that you are seeing is because you are getting a buffer overflow error. In other terms you are not reading your data from the hardware before the next set of data comes in. However, there are many reasons that this could occur.

I would suggest looking at the below knowledgebase article which talks about some of the reasons you could be getting this error and possible ways to resolve this issue.

Try this for Windows 7:

Device Manager -> Right click - select Properties -> Select Port Settings tab - Advanced button
