USB communication

Hi,

Is it possible to read and write a text file using a regular usb flash drive in labview? If so, please suggest the ways to accomplish this.

Thanks

Can you be more specific as to what you mean? A USB flash drive looks, at least on my machines, like pretty much any other R/W drive space, so reading and writing to it isn't any different (other than possible considerations of max R/W cycles a flash drive has in its lifetime, or possibly R/W speed compared to a fast hard drive). What difficulty are you having?

It is exactly just like writing to your hard drive.  You just have to make sure your path is going to the correct drive.

Hi I12,

Does Windows detect the USB drive? Does it get a drive name (like E: or similar)?

Can you show a screenshot of the standard WindowsExplorer showing all drives connected to your computer?

LabVIEW does not need to detect.  It just needs Windows to create a path to the drive (D:, E:, G:, etc.).  Then you just use the standard file IO.
