Pneumatic

Introduction

The Pneumatics system uses an air pump and solenoid to control compressed air for moving cylinders. It can turn the pump on or off and extend or retract cylinders through code.

For the examples below, the configured Pneumatics system will be named Pneumatics1, and will be used in all subsequent examples throughout this API documentation when referring to Pneumatic class methods.

Below is a list of available methods:

Actions – Compress or decompress air with an air pump.

• extend – Extend a cylinder.

• retract – Retract a cylinder.

• pumpOn – Turn on the air pump.

• pumpOff – Turn off the air pump.

• pump – Set the on or off state of the air pump.

Getters – Check if the solenoid is connected.

• installed – Returns whether or not a solenoid is connected to the Brain.

Constructors – Manually initialize and configure Pneumatics.

• pneumatic – Creates a Pneumatics object.

Actions

extend

extend extends a cylinder.

Usage:
Pneumatic1.extend(id);

Parameters	Description
id	The cylinder to extend: cylinder1 cylinder2 cylinderALL – Both cylinders

retract

retract retracts a cylinder.

Usage:
Pneumatic1.retract(id);

Parameters	Description
id	The cylinder to extend: cylinder1 cylinder2 cylinderALL – Both cylinders

pumpOn

pumpOn turns the air pump on.

Usage:
Pneumatic1.pumpOn();

Parameters	Description
	This method has no parameters.

pumpOff

pumpOff turns the air pump off.

Usage:
Pneumatic1.pumpOff();

Parameters	Description
	This method has no parameters.

pump

pump turns the air pump on or off.

Usage:
Pneumatic1.pump(state);

Parameters	Description
state	The air pump state: true – Turn the air pump on. false – Turn the air pump off.

Getters

installed

installed returns a Boolean indicating whether the solenoid is connected to the Brain.

• 1 - The solenoid is connected to the Brain.

• 0 - The solenoid is not connected to the Brain.

Usage:
Pneumatic1.installed()

Parameters	Description
	This method has no parameters.

Constructors

pneumatic

pneumatic creates an object of the pneumatic Class in the specified port.

Default Usage:
pneumatic Pneumatic1 = pneumatic(port);

Overload Usages:
pneumatic Pneumatic1 = pneumatic(port, bPumpEnable);

Parameter	Description
port	Which Smart Port that the Pneumatic Solenoid is connected to as PORT followed by the port number, ranging from 1 to 12.
bPumpEnable	A Boolean representing whether to enable or disable the air pump: true – The air pump is set to on at the start of a project. false – The air pump is set to off at the start of the project.

int main() {
  // Initializing Robot Configuration. DO NOT REMOVE!
  vexcodeInit();

  // Create a Pneumatics object in Port 3
  pneumatic myPneumatic = pneumatic(PORT3);

  // Create another in Port 4 that starts with pump enabled
  pneumatic PumpOnPneumatic = pneumatic(PORT4, true);
