Changes the state of GPIO buttons that are configured for output. See Use GPIO on BrightSign Players for additional information.

  • On: Turns on the specified GPIO button.

  • Off: Turns off the specified GPIO button.

  • Set State: Allows you to turn multiple GPIO buttons on or off. The buttons are specified as bits in an integer value; see the documentation for roControlPort.SetWholeState() for an example.

The "button" numbers 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 Interfaces section of the hardware manual associated with your player model to view a mapping of buttons to pins.
