Communication between myRIO RT and myRIO FPGA

[mayankb]

Hi,

I am trying to develop a general control architecture on FPGA side. The idea is to modify the controller parameter values on the RT side and the FPGA side should adapt accordingly. The goal is to avaoid unnecessary compilation/build time for FPGA code.

How can I transfer a parameter from RT to FPGA side?

Thanks,

Mayank

Hello Mayank,

There is a good LabVIEW Help document that should answer your question about available communication methods:

https://www.ni.com/docs/en-US/bundle/labview-fpga-module/page/lvfpgaconcepts/fpga_data_transfer_over...

If you are looking to transfer a large amount of data quickly/deterministically, I would suggest DMA FIFO.

Thank you, Siana.
