Constructor Detail

GPIODigitalOutput

protected GPIODigitalOutput(int gpio_number)

Constructor

Parameters:

gpio_number - the GPIO pin number

Method Detail

setState

public abstract void setState(boolean state)

Sets the Output State

Parameters:

state - the state to set output to

protectUnprovision

public abstract void protectUnprovision(boolean protect)

Set whether we are going to prevent this pin from de-provisioning if a reset is called

Parameters:

protect - set true to stop getting reset from unprovision

getState

public abstract boolean getState()

Gets the last state set

Returns:

the last state set

getOutputPin

public static GPIODigitalOutput getOutputPin(int gpio_number)

Get a GPIO input pin.

Parameters:

gpio_number - the Pin Number

Returns:

If an input pin already exists for that pin number or we were able to create it, will return the GPIOInput. If not, will retrun null
