GPIO Control and Sync multiple boxes
I've been trying to program this but keep running into a hurdle when I add the sync commands. I can sync files that run on their own, and I can have the GPIO button board control a single box, but can't combine the two. I've got the blank file to get multiple machines in sync on startup. After this they'll transition to a logo video file, then all transition to a loop where each display shows different content, but all timed the same. This will loop until I push a button on the board, which will make all of the boxes play a "SPECIAL ANNOUNCEMENT" sort of file. This will loop until I push another button, that takes us back to the logo video file. I've been attempting to do this by using the GPIO buttons at the top of the interactive programming window, and then adding a Synchronize Command to the GPIO event. Am I going about this correctly? Should I utilize the GPIO Commands on some other type of event?
