25. Save and close the VI.
26. 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.
In the Configure Open FPGA VI Reference dialog box, select VI in the Open section.
5.
6.
In the Select VI dialog box that opens, select 5762SampleAcq (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.
Add a While Loop to the block diagram. Place it to the right of the Open FPGA VI Reference
8.
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.
14. Add the IO Module/AI 0 Data N-1 I/O item to the Read/Write Control function by clicking the
handle on the bottom of the control node with the Positioning tool and dragging the edge down.
15. Wire indicators to the output terminals of the IO Module\AI 0 Data N and
IO Module\AI 0 Data N-1 nodes.
16. Add the Close FPGA VI Reference function, located on the FPGA Interface palette, to the right
of the While Loop on the block diagram.
17. Wire the FPGA VI Reference Out terminal of the Read/Write Control function to the FPGA VI
Reference In terminal of the Close FPGA VI Reference function.
