Example code for NI-8451?

[New LBU]

I'm brand new to the world of LabView, and I was looking at the:

Using the National Instruments USB-8451 I2C and SPI Interface to Evaluate a Texas Instruments Analog...

link to gain a little understanding on how to go about testing (reading/writing) my device.  I am currently stuck on the area where I need to

use the Advanced API for the USB-8451 and provide scripting functionality to effectively create the custom transactions of the serial

operations I wish to perform.  In the Example found in the link above, the example code they provided at this juncture is not linked, it's

broken.  Is it possible to fix this link? And if not is there a link to another sample code that I can use to inspire me on how to go

about programming the interface between the NI-845 and my device?

P.S. Yes, I paraphrased some of my question from somewhere else...

Hi there,

As long as you have the 845x driver installed, you can also find example programs for I2C and SPI in the LabVIEW example finder.  You can go to Help  > Find Examples, then Browse to Hardware Input and Output > I2C and SPI.  There you will find both Basic and Advanced examples for I2C and SPI. 

You might also want to check out the Software User Manual for more information.

Hope this helps!

So there's no way to revive the code for this example project??? 😞

Hey,

What exactly do you mean by "revive the code" for this example?  When you click on an example program (as Adam mentioned above), the front panel opens.  From there you can go to the block diagram by going to "Window">>>"Show Block Diagram".  This will take you to the block diagram for the program, which contains the graphical source code for the example program.  Let me know if you have anymore questions.

Hi,

i am using USB-8451 and trying to communicate with GUI.

i don't see any communication between them, how to check the USB-8451 is working ? i can see the LED is blinking.

is there any standard GUI from NI to test USB-8451 is working or not ?

if there any GUI like that ? please send me the link.

and where can i find example programs ? 

Thanks,

Pavan

Unfortunately, there is no test GUI for the USB-845x.  But there are plenty of examples in the LabVIEW Example Finder (Help->Find Examples).
