Your block diagram should now resemble the block diagram in Figure 6.
Figure 6.
5731/5732/5733/5734SampleAcq (FPGA).vi Block Diagram
Tip
Click the
Clean Up Diagram
button on the toolbar to cleanly organize the VI block diagrams.
20. Save the VI as
573xSampleAcq (FPGA).vi
.
21. Click the
Run
button. LabVIEW creates a default build specification and begins compiling the VI.
The
Generating Intermediate Files
window opens and displays the code generation progress.
Next, the
Compilation Status
window opens and displays the progress of the compilation. The
compilation takes several minutes.
22. Click
Close
in the
Compilation Status
window.
23. Save and close the VI.
24. Save the project.
Creating a Host VI
1.
In the
Project Explorer
window, right-click
My Computer
and select
New»VI
. A blank VI opens.
2.
Select
Window»Show Block Diagram
to open the VI block diagram.
3.
Place the Open FPGA VI Reference
function, located on the
FPGA Interface
palette, on the block
diagram.
4.
Right-click the Open FPGA VI Reference function and select
Configure Open FPGA VI
Reference
.
5.
In the
Configure Open FPGA VI Reference
dialog box, select VI in the
Open
section.
6.
In the
Select VI
dialog box that opens, select
573xSampleAcq (FPGA).vi
under your device and
click
OK
.
7.
Click
OK
in the
Configure Open FPGA VI Reference
dialog box. The target name appears under
the Open FPGA VI Reference function in the block diagram.
8.
Add a While Loop to the block diagram. Place it to the right of the Open FPGA VI Reference
function.
9.
Right-click the conditional terminal inside the While Loop and select
Create Control
to create a
STOP button on the VI front panel window.
10. Add the Read/Write Control function, located on the
FPGA Interface
palette, inside the
While Loop.
11. Wire the
FPGA VI Reference Out
output terminal of the Open FPGA VI Reference
function
to
the
FPGA VI Reference In
input terminal on the Read/Write Control
function.
12. Wire the
error out
terminal of the Open FPGA VI Reference function
to the
error in
control of
the Read/Write Control
function.
13. Configure the Read/Write Control function by clicking the terminal section labeled
Unselected
, and
selecting
IO Module/AI 0 Data N
.
