Trouble taking data from event structure
Résolu !
Hello, I'm trying to build a producer consumer loop.
My issue comes when I want to take the value of some buttons I am displaying on front panel. I don't know how to use the data onto the other loop.
My attempt is to use it to compare on the consumer loop, however I don't know how to transport this down there.
General Picture:
Any suggestions are welcome. 😋
Instead of using a queue with just a command enum, make it a cluster with a command enum and a variant. Then you can send whatever you'd like to your other queue. You'd of course need to convert it back from a variant, but you'll always know what type it is ahead of time anyway.
Is this what you suggest?
How do I input the data in the variant? do I have to unbundle it too?
You already do the compare in the consumer loop, right?
If you want to do the compare in the event loop, use event data nodes for new value and old value.
You really need to rethink your approach to the entire program. adding piles of complication does not make the program better by any definition.
Some more comments:
- Loop.vi: Your loop VI should only have one input. The constant belong inside the subVI as diagram constants.
- checkbutton.vi: the -1 exception belong inside the subVI.
- trnasaction.vi: Get rid of that refernce and property node. Pointless. Find a logical terminal layout. This is NOT it!

Use a "Bundle" node, wire your data into the Variant input. LV will convert it to variant automatically, but you'll have to use Variant to Data to convert it back to usable data. Tip, do this inside the specific instruction's loop. This way each instruction can have its own data types.
