The Pneumatics Control Module (PCM) is a CAN-based device that provides complete control over the compressor and up to 8 solenoids per module. The PCM 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 PCM module can be used where the modules corresponding solenoids are differentiated by the module number in the constructors of the Solenoid and Compressor classes.
