What is the "Dynamic FPGA Interface Cast" function for?

[Terry_ALE]

In shipping examples, there is one Host VI with a handful of subVIs.  However for more complex systems it is best to make an API for a given bitfile (or group of bitfiles).  The API has a subVI for each control, indicator, and 4-5 for each DMA-FIFO or P2P.  Each API subVI uses a "Dynamic FPGA Interface Cast" function to cast the reference to that specific control, indicator, and 4-5 for each DMA-FIFO or P2P (and nothing else).  This way if the bitfile interface changes, only those parts of the API need to be modified.  This has been especially helpful when you need to make a new Host VI for the same bitfile.  In other cases, parts of the API gets wrapped into bigger functions so that controls on the FPGA are set the same way each time.

Terry,

Thanks for the reply. Appreciate the clarification.

Hi

Could you state the name of the example. I'm struggling to find it....😳

Thanks
