FPGA interface dynamic does not connect with FPGA interface based Vi

[SASA1]

Hi all,

   I have to use a vi (using an FPGA interface in in its inpouts), in an other Vi (which call directly FPGA Dynamic ( when i opened FPGA reference and configure with an FPGA vi or a bitfile the FPAGA interface take dynamic by default)

  but i cannot connect the two vi by they FPGA references (plz see picture).

  did anyone had had this problem before and what is the solution for that?

  Regards,

Hi SASA,

use a typedef for your FPGA reference. Use that typedef in your subVIs and in the OpenFPGARef function call ("Bind FPGA host reference to typedef")…

Using a Dynamic FPGA Reference is now considered preferable to using a type definition.

You need to modify the FPGA Reference control on the subVI to accept a dynamic VI reference, which you can do by right-clicking on it, then configuring it to accept a dynamic reference containing the controls, indicators, and methods that the subVI accesses on the FPGA.

Hi GerdW,

  Thank you.

  it works with your solution, but it create another problem with another vi (see picture).

Hi SASA,

you need to use that typedef in each instance you operate on this FPGA ref…

OK, i got the point, but the solution that nathand is proposing, is a attrackting me, 

but i could not found the how i can change the FPGA reference to be compatible with FPGA dynamic reference

i mean when i right cllick on the FPGA reference, what icon i shall use

Hi SASA,

nathan's solution is proposed for current LabVIEW versions. As I'm limited to LV2011 I cannot comment on this one.

Edit/Correction: Even LV2011 has this "Dynamic FPGA Interface Cast", but I didn't use it so far…

Sorry, it's not a right click option. Instead you should create a control or indicator from the dynamic FPGA reference wire, or use the Dynamic FPGA Reference constant and change it to a control as explained here:http://zone.ni.com/reference/en-XX/help/371599K-01/lvfpgahosthelp/fpga_dynamic_host_interface/
Note that you can make the dynamic reference a type definition which may be helpful if you're using it in multiple places.

i got the point, just creat controls on the FPGA interface wire and configure to use dynamic mode.

but i saw in the link that its a help page for LV 2014. is it working for LV 2013 i'm using ?

nathan, can you please see the picture attached, it describe that i cannot find  the dynamic box in the configuration
