FPGA configuration using .NET

[CAS_MattF]

I have a customer request to have an .NET application send configuration settings to an LabVIEW FPGA application.  What method would someone recommend?  The other request would be to send back results to the FPGA application when complete.  I am looking for a good starting point to communicate between LabVIEW FPGA and a .NET application.

Thanks!

Matt,

Could you explain a little more about what these configuration settings you are sending are?

As far as a starting point for communicating between LabVIEW FPGA and .NET application, I would recommend reading our Introduction to the FPGA Interface C API linked below.

We are looking at creating middle ware that would be a LabVIEW application.  Would exchange the data using a TCP/IP communications between LabVIEW and .NET.  Would use DMA FIFOs between LabVIEW and LabVIEW FPGA.  Configuration is a 2D array of numeric data.  When the program runs they wants to buffer 3,000 samples a second from the FPGA and send back to .NET.  Any additional thoughts?

if you are communicating using TCP/IP then the fact that the other application is .net is not a factor.

open a socket and read and write.  no different than LabVIEW to LabVIEW other than you have to match byte order and data types etc.  your original post implied you wanted to talk to the FPGA directly from a .net application where you would need to use the c-interface

the application builder can create a LabVIEW .net interop for you that is callable from any other app
