Hello,
I have a .vi containing a state machine whose main data cluster has a handle for a camera I am using. The user needs to be able to set the brightness, shutter speed, etc. on the fly, so I have another loop containing an event structure waiting on changes to these values. However, to use the camera's API, I need its handle, which is in the other loop. What's the best way to access this data? The data cluster, right now, is not a control or indicator, so I can't make a local variable. I suppose I could write the camera handle to an indicator, then access it with a local variable, but I'd rather not clutter up the front panel with data the user doesn't need.
Also, I currently have the brightness, shutter speed, and gain controls inside a cluster (is it good pracice to keep controls inside clusters?) However, I'm concerned that if I put the terminal for this cluster inside the event structure loop but outside the event structure itself, the old value will be read for the variables it contains. For example, if you had not a cluster but a stop button in this position, then the value would be read as soon as the loop began, so when you wired it into the event structure, you would get the value before the change. But the cluster has variables useful for 3 separate events, so I have to put it outside. If I unbundle it INSIDE the event structure, will I get the new values, or the old ones? I could use a local variable for two of the events, but that would be ugly.
Thanks!
