In the FPGA Register Properties dialog box, select Initial Value from the Category list to display this page.

Use this page to initialize a register item. You can enter an initial value or call an initialization VI that you create.

This page includes the following components:

  • Use Initialization VI—Specifies whether LabVIEW uses an initialization VI that you create. The default is unchecked.
    Note  You must use an initialization VI if you have specified Custom control as the data type for the register item.
  • VI Path—Specifies the path to the initialization VI.
  • New VI from Template—Creates an instance of a template VI, saves the VI to the location you specify in the Name the New Initialization VI dialog box, and opens the VI. You must close the FPGA Register Properties dialog box to edit the VI.
  • Open VI—Opens the VI you specify in the VI Path field. You must close the FPGA Register Properties dialog box to edit the VI.
  • Run VI—Runs the VI you specify in the VI Path field. LabVIEW then imports the output value into the register item and displays the corresponding value in the Initial Value field.
  • Initial Value—Indicates the initial value of the register item. If you do not select an initialization VI, use this control to specify an initial value.
