Labview Code Stream High Speed Data Between Fpga Developer walk through for the "rt fpga dma fifo" labview project available for download at learn cf.ni teach riodevguide code rt fpga dma fifo.h. I suspect you need to actually start and run the fpga vi within the rt vi. something using the following vis: open fpga vi reference and invoke method (e.g. run). as gerd said, there are existing examples that will show this (this is taken from the "streaming data (fifo)" example found via searching for "dma fifo" in the example finder): 0 kudos.

Labview Code Stream High Speed Data Between Fpga And Access to a dma fifo is always through an array on the host (rt) side, and through individual elements on the fpga. that way the host side can process a bunch of elements as a group, efficiently, while the fpga generates or reads them individually. there is no loss of data unless the dma fifo overflows (runs out of space). 2 kudos. message 2 of 8. This example demonstrates how to use dma fifos to send data to and from an fpga target (bidirectional data transfer). this project is configured to work with a pxi 7841r on a windows computer, but this same code will work on any fpga target and a windows or a real time host. this example generates a user defined waveform and sends it down to. Download and unpack the rt fpga dma fifo.zip (for use with ni myrio 1900) or the nielvisiii rt fpga dma fifo.zip (for use with ni elvis iii) archive, and then double click the ".lvproj" file to open the project. note: this project was written for a ni myrio 1900 or ni elvis iii connected by usblan at ip address 172.22.11.2.

Features. ideal for high speed data streaming between two endpoints, one on the rt target and the other on the pc host. transfers any labview data type, however, best performance is achieved with numeric scalars, booleans, and 1 d arrays of the same. similar to the dma fifo technique to stream data between the rt and fpga and the pc and fpga.
