Use FPGA Up Cast function to interact with different FPGA VIs

[S.Limb]

Overview

The example demonstrates how to use the Up Cast function to convert a FPGA VI-specific reference to a more generic reference.

Description

The LabVIEW FPGA Up Cast Function converts an FPGA VI-specific reference to a more generic reference. You then can use common code to interact with different FPGA VIs/bitfiles. The FPGA targets must be of the same class, so they have to have the same FPGA VI front panel controls and DMA FIFOs. You may want to use this function if you want to evaluate different algorithms in a host VI without rewriting the host VI. Some FPGA targets might not support this function.

The example demonstrates how to use the Up Cast function and shows the difference between the Target and Interface mode of the Up Cast function in a commented disable structure.

Requirements

 Software

• LabVIEW 2012 Base Development System (or compatible)
• LabVIEW 2012 FPGA Module (or compatible)

 Hardware

• No hardware is necessary to use this example VI (in simulation mode)

Steps to Implement or Execute Code

1. Open the attached file
2. Select the mode to decide which FPGA VI will be loaded
3. Run the VI
