Enum GPIOPin

java.lang.Object

java.lang.Enum<GPIOPin>

com.raspoid.GPIOPin

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<GPIOPin>

public enum GPIOPin
extends java.lang.Enum<GPIOPin>

This enum is used to restrict access to classical programmable Gpio pins.

Those GPIO numbers correspond to those used by WiringPi.

The Raspberry Pi with 40-pin expansion header (cfr J8 Pinout (40-pin Header)) provides access to 26 programmable GPIO pins ([00,16] + [21,29] (GPIO [17,20] are not existing, for historical compatibility reason with Raspberry Pi Model B (Revision 2.0) additional P5 header).

We removed I2C, PWM and UART pins from those GPIO pins to avoid compatibility issues. You can then freely access each programmable GPIO pin from this enum to control LEDs, buttons, and others.

Method Detail

values

public static GPIOPin[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (GPIOPin c : GPIOPin.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static GPIOPin valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null

getPin

public Pin getPin()

Get the Raspoid pin abstraction for this GPIOPin.

Returns:

the Raspoid Pin ocject corresponding to this GPIOPin.

See Also:

Pin

getWiringPiPin

public com.pi4j.io.gpio.Pin getWiringPiPin()

Get the WiringPi abstraction object corresponding to this Raspoid GPIOPin.

Returns:

the corresponding WiringPi pin (pi4j.io.gpio.Pin instance) or null if no corresponding object found.
