How can I communicate between two fpga targets

[irfan789]

Hello everybody

I need to communicate between two fpga targets to know whether they are working or not...how can I do that...

Is it called handshaking and acknowledgement concept?If yes how can I do that ?

Hi irfan,

you could use two digital signal lines between those FPGAs to signal data or handshake each other.

Or you use their RT hosts to speak with each other over a network connection…

FlexRIO can do FPGA P2P streaming: http://www.ni.com/white-paper/10801/en/

Other FPGA targets cannot though, GerdW has you covered for those options.
