Hi Rajesh,

is it correct now ?

Atleast you built the same code as I have shown in my message.

You still need to wire the VISA reference, include some error handling, and so on…

i am new to labview.

There is a Training section in the header of this LabVIEW board!

(You should learn to spell LabVIEW the right way. 😄 Apart from spelling you also should learn to use the AutoCleanup tool…)

thank you so much 🙂 

i will go through the classes.

need suggestion:

my VI should perform first WRITE then READ . how to control flow.

how to implement .

Hi Rajesh,

i will go through the classes.

In those lessons you should get notified about the ExampleFinder in LabVIEW!

need suggestion:

To learn THINK  DATAFLOW you could use any example VI in the ExampleFinder!

Everything provided to you this far is correct and good.

however.....

USB control of devices which don't correspond to one of the standard USB device types (Mass Storage, Audio, HID etc) is challenging.  I've written posts on this in the past and it's actually very complicated if your device isn't one of the standard device types.

Do you have a VID and PID of your device so that I can do a quick check. If it's a custom USB device, this will not be a task for a beginner.

My device has VID & PID.

i followed "http://www.ni.com/tutorial/4478/en/" procedure to detect my device as USB.
