The Pneumatic Hub (PH) is a CAN-based device that provides complete control over the compressor and up to 16 solenoids per module. The PH is integrated into WPILib through a series of classes that make it simple to use.
The closed loop control of the Compressor and Pressure switch is handled by the
Compressor class (Java, C++), and the Solenoids are handled by the
Solenoid (Java, C++) and
DoubleSolenoid (Java, C++) classes.
An additional PH module can be used where the module’s corresponding solenoids are differentiated by the module number in the constructors of the Solenoid and Compressor classes.
