Gpio class abstract
Base GPIO interface supported by all GPIO implementations.
- Implementers
Constructors
- Gpio()
Properties
- hashCode → int
-
The hash code for this object.
no setterinherited
- pollingFrequency ← Duration
-
Set the polling frequency for any GpioInput.values streams.
The default polling frequency is every 10 milliseconds.

nullto turn off polling.no getter - runtimeType → Type
-
A representation of the runtime type of the object.

Methods
-
allocatePin(
int physicalPin) → void - Check that the pin can be used for GPIO and that is has not already been allocated. This should be called by subclasses not clients.
-
dispose(
) → Future - Call dispose before exiting your application to cleanup native resources. Returns a future that completes when cleanup has finished.
-
input(
int physicalPin, [Pull pull = Pull.off]) → GpioInput -
Return a GPIO pin configured for input,
where
physicalPinis the physical pin number not the GPIO number. -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
output(
int physicalPin) → GpioOutput -
Return a GPIO pin configured for output,
where
physicalPinis the physical pin number not the GPIO number. -
pwm(
int physicalPin) → GpioPwm -
Return a GPIO pin configured for software based PWM,
where
physicalPinis the physical pin number not the GPIO number. -
throwPinAlreadyAllocated(
int physicalPin) → void -
toString(
) → String -
A string representation of this object.

Operators
-
operator ==(
Object other) → bool -
The equality operator.
