This object is used to control and wait for events on the BrightSign generic

GPIO control port. Typically, LEDs or buttons are connected to the

GPIO port. Turning on a GPIO output changes the voltage on the GPIO port to 3.3V. Turning off a GPIO output changes the voltage on the GPIO port to 0V.

The GPIO ports are bidirectional and must be programmed as either inputs or outputs. The IDs range from 0–7. The SetWholeState() method will overwrite any prior output settings. The SetOutputState() takes an output ID (1, 2, or 6, for example). The SetWholeState() method takes a mask (for example, SetWholeState(SetWholeState(2^1 + 2^2) will set IDs 1 and 2).

The JavaScript equivalent is controlport.
