RTSI implemention between FPGA and PXI controller

[Akiel]

I have a need to be able to send and receive data from a r-series modules. I note these have an RTSI bus (PXI form). I am looking to implement this bus so I can pass results to a PXI controller and send new settings (info for PWM), can someone point me at an article as I have been looking for a while now to no avail.

Many thanks

To pass data from an FPGA depending on the data type it is common to use a FIFO as R series cards tend to gather data faster than most devices can handle so the buffer is used so data isnt lost. If you could post some example code I would be happy to point you in the right direction.
