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.
Note
The "button" numbers described above are not the same as GPIO "pin" numbers: Some pins act as power supply or ground, so they are not included in the button numbering scheme. See the hardware manual associated with your player model to view a mapping of buttons to pins.
