public final class GpioService
extends AbstractService

This service provides a way to interact with GPIO pins on the main cpu board. The GPIO adapter needs to be spawned which will then connect a session to this service.

Method Details

createInputPin

public GpioInputPin createInputPin(String name,
 int pin,
 boolean inverted,
 GpioInputPinListener listener)

Create an input pin with the specified name for the local node. Allows the physical signal to be inverted to take advantage of the debouncing which is fast on, slow off.

Parameters:

name - the name of the pin bean

pin - the pin number

inverted - if true, invert the physical signal

listener - listener for pin change events

createInputPin

public GpioInputPin createInputPin(NodeId nodeId,
 String name,
 int pin,
 boolean inverted,
 GpioInputPinListener listener)

Create an input pin with the specified name for the specified node. Allows the physical signal to be inverted to take advantage of the debouncing which is fast on, slow off.

Parameters:

name - the name of the pin bean

pin - the pin number

inverted - if true, invert the physical signal

listener - listener for pin change events

createOutputPin

public GpioOutputPin createOutputPin(int pin,
 boolean inverted,
 GpioOutputPinListener listener)

Create an output pin for the specified pin number, on the local node.

Parameters:

pin - the pin number

inverted - if true, invert the output signal

listener - the output pin listener

createOutputPin

public GpioOutputPin createOutputPin(NodeId nodeId,
 int pin,
 boolean inverted,
 GpioOutputPinListener listener)

Create an output pin for the specified pin number, on the specified node.

Parameters:

pin - the pin number

inverted - if true, invert the output signal

listener - the output pin listener

addListener

public void addListener(int pin,
 GpioListener listener)

Add a listener for gpio events, on the local node.

Parameters:

pin - the pin to get events from

listener - the listener to add

addListener

public void addListener(NodeId nodeId,
 int pin,
 GpioListener listener)

Add a listener for gpio events, on the specified node.

Parameters:

pin - the pin to get events from

listener - the listener to add

getManifestService

public ManifestService getManifestService()
