fpga: By-passing the Host VI when passing data from the FPGA

[RPluth]

I've created an FPGA VI that is counting pulses, read from a DIO, for a settable amount of time, for example 5 msecs.  I've created a Host VI that communicates with the FPGA VI.  I've taken all of that and created a DLL out of it to be used by a non-LabView application to communicate with my FPGA application.

However, what I'd really like is for the FPGA application to periodically send the pulse count directly to my non-Labview application.  Bottom line, I'd like the FPGA VI to do something like send an interrupt every so often to my non-Labview application, then have the ISR in my application update an internal variable in my application.

Is there anyway to by-pass the Host VI, and get data from the FPGA VI to go directly to my application?


Thanks,
Rick

Hi Rick,

The only way to communicate with the FPGA VI is through the FPGA Interface VIs in the Host VI.  To use third-party software you need to create a DLL, as you have done.  It sounds like your current approach is the best option.
