Peer to peer streaming PXIe 1082 and FPGA 7976

[arjun22]

I am trying to get a simple peer to peer streaming from one FPGA to the other in an 

NI PXIe 1082 work. The FPGAs connected are 7976. 

Following  the instructions given in here

https://zone.ni.com/reference/en-XX/help/371599G-01/lvfpgahelp/fpga_p2p_intro/

I created an FPGA vi under each target, one for the reader and other for writer. PFA the vi snippets.

The writer simply writes a constant value of 1, the reader attempts to read it and passes it to a control.

This control is read from the FPGA by the host vi and is displayed.

Now in the host vi, I connected the two streams using niP2Pcreate peer to peer streaming. I have compiled the FPGA vi

(Each compilation takes about 45 minutes) and then executed the host vi. That results in an error that says

"Error 308021 occurred. Possible Reasons: NIP2P: The provided endpoint handle is invalid"

Could someone please help me with the right way of getting a simple peer to peer streaming work.

Thanks,

Arjun

Hi Arjun,

I went through the Snippets you provided. After creating the P2P stream you need to enable it also. It would be best if you can go through the shipped examples in the LabVIEW for P2P streaming. Please refer to the Snippet I attached of the vi and also the example that is shipped with LabVIEW. You can directly use the project by changing the FPGA Target to that of yours and use.

Hope this helps

Thank you Yaskadeva. That code works. I did not know about example finder too.
