Open FPGA Reference

[lavalolo]

Hello,

Is there a way to use the "FPGA Reference" in different Host Vi's without using the "Open FPGA Reference" each time ?

I tried this with LabVIEW Globals but got an Visa Poke... error.

I have a state machine running down on the fpga card and control the states with different host Vi's.

I use different host Vi's because i build an dll out of the host vi's and so get several (C-)functions which i call

in a CVI project.

This works great, but the bad thing is the execution time. Each "Open FPGA Reference" needs about 90..110ms

and this is really to much for the project I'm working for .

I'm looking forward to every reply concerning this topic !

Thanks in advance, Andreas

Sorry, i posted to early, my mistake.

After writing the HW reference to a LabVIEW Global i closed the reference at the end of the Vi.

So the reference was no longer available when calling it from another VI .

Now it works great, execution times are about 300 us... :thumbup:
