Hi, I am wondering how the data streaming works from my PXIe-5774 to the host computer on the getting started example program. I can see from the FPGA code that the data is sent to two FIFOs (as per usual) seen in this screencap of the example code that you can get from (Hardware input and output -> FlexRIO -> Integrated IO -> Getting Started): (Yes I can read what it says on the comment on the loop) On the host side though I don't see a similar fifo but instead I see a call library function node. I understand that the stream instance controls to which instance the data is sent and where it comes out but I tried to change the fifos on the FPGA side to stream.to host 1.0 and 1.1 and the instance on the host code to 1 but labview gives me an error (labview fpga Attribute is undefined or not present in the currently running session. Property: Stream Finite Channel Name: 1). Can I change the FIFO settings on the project and can I create new fifos for the same instance or for a different instance? How is this accomplished? How does this streaming work in general? Just very confused about this FlexRIO FPGA stuff... ThanksAarni

LabVIEW

And no error?

Either put a few probes on the error wire or create an error indicator in the loop.

how did find the FIFO.start block, I tried the invoke method but i cant find the start choice.
