Get access to FPGA I/O from the host VI

[CyGa]

Hi!
I'm pretty new in programming FPGA and I have a simple question. I've programmed basic fonctions to send or read signals on digital I/O (7813R).
But I'd like to control which line has to read or output a signal from the host target... I tried to use a "Read/Write Control" but the ressources doesn't appear (they are programmed as controls on FPGA VI front panel)...
Is there any solution ?

Hey Zyl7 - In the host VI, have you opened the FPGA reference and selected either a compiled bitfile or a VI reference?  Do you have the front panel objects on the FPGA VI?  In order to see elements in the Read/Write Control, you must have front panel objects on the FPGA VI and you must properly open the FPGA reference.

Hope that helps!

Hey Bryan,
thank you for your answer ! i confirm that the FPGA reference is opened and the bitfile is correctly loaded. As the other controls, the resources controls are on the front panel of my FPGA VI... In the host VI, i can have access to my other controls (enum, and other numeric controls...) using Read/Write Control but not to the resources...

Zyl7 or Brian,

Was this issue ever resolved?  If so, I'd like to hear the solution because I have the same issue.

Thanks!

Hi!
At the end, I'm using Constant Ressources in the FPGA code... It obliged me to restrict my hardware configuration to fit FPGA programming constraint...

Thanks for your reply, Zyl7!  Sounds like you decided not to have the option of selecting the resource from the Host VI anymore.

I, however, am still interested in being able to select the resource from the Host VI, but as Zyl7 stated in his original post, I don't seem to have access to it.  Why?  Brian R., do you have any idea?
