USB vi

[Bertrand Jacquet]

Hello,

I'm searching a way to use the usb port with labview (5.1). Do you know
where could I find exemples V.I. ? I can't find it on the ni.com website.

Thanks in advance,

BJA

It all depends on the driver for that particular usb unit...In many cases the driver will emulate e.g. a serial port and then you can use the standard serial functions...Otherwise you will need to interface using accompanying dll/activeX drivers if such is provided.

I am using LabVIEW 6.1 for Linux together with a few CIN's and libusb (
http://libusb.sourceforge.net ) and it works well.

Hi Stefan,

I am interested in using a USB device with labview + libusb library.

I tried to use the DLL import function for test with the usb_init, usb_find_busses and usb_get_busses however got error messages. The structure of usb_bus and usb_device seems to be to complex for labview. Is it necessary to write a CIN for this? Is there any sample code on the web or application examples?

Thanks for your time,

Andreas
