Pneumatics #

Introduction #

The pneumatics class is used to control a VEX V5 Pneumatics device connected to a 3-Wire port.

It provides methods for activating a solenoid to extend or retract a pneumatic cylinder. The Pneumatics device must be manually constructed in code and cannot be added using the Device Menu in VEXcode V5.

Class Constructors #

pneumatics( triport::port &port );

Class Destructor #

Destroys the pneumatics object and releases associated resources.

~pneumatics();

Parameters #

Parameter	Type	Description
`&port`	`triport::port`	The 3-Wire Port the Pneumatic Solenoid is connected to, written as `Brain.ThreeWirePort.X` or `ExpanderName.X`, where `X` is the port letter (for example, `Brain.ThreeWirePort.A` or `Expander1.A`).

Notes #

This class can only be constructed manually in code, as it cannot be constructed using the Device Menu in VEXcode V5.
A Brain or 3-Wire Expander must be created first before they can be used to create an object with the pneumatics class constructor.

Example #

// Create the pneumatics instance on 3-Wire Port A
pneumatics PneumaticsA = pneumatics(Brain.ThreeWirePort.A);

Member Functions #

The pneumatics class includes the following member functions:

open — Sets the pneumatics device to the solenoid open state allowing air to flow into the cylinder.
close — Sets the pneumatics device to the solenoid close state stopping air flowing into the cylinder.

Before calling any pneumatics member functions, a pneumatics instance must be created, as shown below:

/* This constructor is required to use a
V5 Pneumatics Solenoid when not configured as
a Digital Out device. Replace the values
as needed. */

// Create the pneumatics instance on 3-Wire Port A
pneumatics PneumaticsA = pneumatics(Brain.ThreeWirePort.A);

open #

Sets the pneumatics device to the solenoid open state allowing air to flow into the cylinder.

Available Functions

void open();

Parameters

This function does not take any parameters.

Return Values

This function does not return a value.

Examples

// Open the solenoid to extend the cylinder
PneumaticsA.open();

close #

Sets the pneumatics device to the solenoid close state stopping air flowing into the cylinder.
