4.6-GPIO Event

The GPIO Event specifies the action that occurs when a specific GPIO button is pressed or input is received. By default, the playlist toolbar includes several GPIO buttons that you can use to define interactions.

• Specify button number: Specify the number of the GPIO button. These numbers also correspond to the 8 bi-directional pins on the GPIO connector. 
• Trigger Event on Button: Specify whether the event should trigger when the button is depressed (Down) or when it is released (Up). If you've selected Down, choose one of the following behaviors:
  • Press (First Touch): The event triggers the moment the button is depressed.
  • Press Continuous: The event triggers the moment the button is depressed, then continues triggering at the specified intervals as long as the button is depressed.
