Using Your Device with a LabVIEW FPGA Example VI
Note
You must install the NI FlexRIO Adapter Module Support software before running this
example. Refer to the NI FlexRIO FPGA Module Installation Guide and Specifications for more
information about installing your software.
The NI FlexRIO Adapter Module Support software includes a variety of example projects to help get
you started creating your LabVIEW FPGA application. This section explains how to use an existing
LabVIEW FPGA example project to generate and acquire samples with the NI 5731/5732/5733/5734R.
This example requires at least one BNC cable for connecting signals to your device.
Note
The examples available for your device are dependent on the version of the software and driver
you are using. For more information about which software versions are compatible with your device,

Each NI 5731/5732/5733/5734R example project includes the following components:
•
A LabVIEW FPGA VI that can be compiled and run on the FPGA embedded in the hardware
•
A VI that runs on Windows that interacts with the LabVIEW FPGA VI
Note
In the LabVIEW FPGA Module software, NI FlexRIO adapter modules are referred to as
IO Modules.
Complete the following steps to run an example that acquires a waveform on AI 0 of the
NI 5731/5732/5733/5734.
1.
Connect one end of an BNC cable to AI 0 on the front panel of the NI 5731/5732/5733/5734 and
the other end of the cable to your device under test (DUT).
2.
Launch LabVIEW.
3.
In the Getting Started window, click Find Examples to display the NI Example Finder.
In the NI Example Finder window, select Hardware Input and Output»FlexRIO»IO Modules»
4.
NI 573X»NI 573y (where y represents the device number you are using).
5.
Select NI 573y - Getting Started.lvproj. Wait for the project to finish opening.
6.
In the Project Explorer window, open NI 573y - Getting Started (Host).vi under My Computer.
The host VI opens. The Open FPGA VI Reference function in this VI uses the NI 7952R as the
FPGA target by default. If you are using an NI FlexRIO FPGA module other than the NI 7952R,
complete the following steps to change to the FPGA VI to support your target.
a.
Select Window»Show Block Diagram to open the VI block diagram.
b.
On the block diagram, right-click the Open FPGA VI Reference (PXI-7952R) function and
select Configure Open FPGA VI Reference.
c.
In the Configure Open FPGA VI Reference dialog box, click the Browse button next to the
Bitfile button.
d.
In the Select Bitfile dialog box that opens, select the bitfile for your desired target. The bitfile
name is based on the adapter module, example type, and FPGA module.
e.
Click the Select button.
f.
Click OK in the Configure Open FPGA VI Reference dialog box.
g.
Save the VI.
7.
On the front panel, in the RIO Resource pull-down menu, select a resource that corresponds with
the target configured in step 6.
8.
Select AI 0 in the AI Channel control.
