Using global variables with FPGA VI and an main VI

$

First off, I am fairly new with labview.

 

I am wondering if it was possible to obtain data from an FPGA VI so that it can be read in a regular VI.

 

I tried using global variables, but the data doesn't update.

 

Basically what I tried doing was using a Global Variable and have it in write mode in the FPGA, and then have it in read mode on the regular VI with an indicator attached to it. But I am not getting data out of it, it just stays zero. I intend to use this data as part of my main program.

 

Is there a way I can achieve this, or is there another method?

 

Thanks!
