You can use FPGA I/O Method Nodes to invoke methods, or actions, on the FPGA I/O items and C Series modules present in the project. The available methods depend on the FPGA target and the FPGA I/O item or C Series Module you select.

Complete the following steps to create and configure an FPGA I/O Method Node.

Add an FPGA I/O Method Node to the block diagram.
Right-click the FPGA I/O Method Node and select Select Item from the shortcut menu. The Select Item submenu displays the FPGA I/O items and C Series modules present in the Project Explorer window under the FPGA target. Select the FPGA I/O item or C Series module you want to use. Alternatively, you can write reusable code by wiring an FPGA I/O control to the FPGA I/O In input of the FPGA I/O Method Node.
Right-click the FPGA I/O Method Node and select Select Method from the shortcut menu to select a method to which you want the FPGA I/O item assigned. LabVIEW displays the methods available for the FPGA target in the Select Method submenu. LabVIEW displays No Methods Available in the shortcut menu if the FPGA target does not support methods for the FPGA I/O item or C Series module you select. Refer to the specific target hardware documentation for information about the methods the FPGA target supports.

Tip You also can click the FPGA I/O Method Node and use the shortcut menu to select methods available for the FPGA target.
After you select a method from the shortcut menu, LabVIEW displays the method and the terminals for that method in the FPGA I/O Method Node. Wire the terminals that you need.
