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 block diagram window.
3. Place the Open FPGA VI Reference function (from 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 window, select the VI button.
6. In the Select VI window that opens, select the Static RW with Voltage (FPGA).vi under your
device, and click OK.
7. Select the Run the FPGA VI checkbox if it is not already selected.
8. Click OK in the Configure Open FPGA VI Reference window. The new target name appears
under the Open FPGA VI Reference function on the block diagram.
9. Add a While Loop to the block diagram, as shown in Figure 15.
10. Add the Read/Write Control function (from the FPGA Interface palette) inside the While Loop.
11. Wire the Open FPGA VI Reference function FPGA VI Reference Out indicator to the FPGA VI
Reference In control on the Read/Write Control function.
12. Wire the Open FPGA VI Reference function error out indicator to the Read/Write Control
function error in control.
13. Click the Unselected input of Read/Write Control function and select Voltage Level.
14. Wire a control to the Voltage Level FPGA input terminal.
15. Expand the bottom of the Read/Write Control function to expose five more nodes. Click the new
nodes and select each of the remaining items.
16. Wire indicators from the IO Module\SE_Data_Rd and IO Module\Set_Voltage_Done output
terminals.
17. Wire controls to the IO Module\SE_Data_Dir, IO Module\SE_Data_Wr, and
IO Module\Set_Voltage_Family input terminals.
18. Add the Close FPGA VI Reference function (from the FPGA Interface palette) outside the
While Loop.
19. Wire the Read/Write Control function FPGA VI Reference Out indicator to the Close FPGA VI
Reference function FPGA VI Reference In control.
20. Wire the Read/Write Control error out parameter to the Close FPGA VI Reference error in
parameter.
