Read/Write FPGA controls by label text – open-source utility

[AndersSekanina]

Hi,

I've always wanted to read and write FPGA controls by name rather than wiring everything explicitly. Couldn't find a good solution, so I made one.

It generates two VIs for your FPGA target — one for reading, one for writing — both taking a control name as a string input.

Has anyone solved this in a better way, or have suggestions? I'd like to know.

This library is included with the R Series device driver versions 21.0 and later.

This library is used in FPGA Addon Custom Device

Thank you, I was actually not aware about that.

I have tested it, and it works well. There is however about 1.2 ms overhead if I open and closes the FPGA sub-reference every time. I must see if I can find a nice way to keep them open, else I will get into timing issues at the cRIO.

What's your use case? Why you couldn't pass the FPGA refnum instead of re-opening it?
