Hey all,
we're in a early design phase of a measurement setup and are more or less selecting parts and checking if the things we need are feasible with the chosen ones. In this context, I have some questions regarding the backplane PXI_Trig lines:
Can the PXI_Trigger lines be reserved and driven by software (Windows 10 C/C++ application, not LabView) running on the NI PXIe-8840 QC controller to propagate to other peripheral modules? Use case would be a User GUI-Button triggering the sampling.
If so, can someone point me to some C/C++ examples?
If not, can at least the NI PXIe-8840's front panel trigger SMB connector be routed to the PXI_Trig bus on Windows (by now)?
Sorry, for those noob questions. I'm not yet familiar enough with the whole PXIe platform and can neither access some hardware to fiddle around nor the drivers to dig out some matching examples. Furthermore, I'm quite confused by partially contradicting and/or outdated information found in datasheets, manuals and knowledge base articles.
I'm aware that what we want to do (propagate the software trigger via the backplane) is probably solved best using a dedicated Timing Module. But most probably we cannot use one as we are quite strongly constrained to a single NI PXIe-1082DC chassis (i.e. no larger one or two-chassis-setup) and run out of slots due to number of other required modules.
Thanks for your help!
