RpiGpio class

GPIO interface used for accessing GPIO on the Raspberry Pi.

Inheritance

• Object
• Gpio
• RpiGpio

Properties

hashCode → int

The hash code for this object.

no setter, inherited

pollingFrequency ← Duration

Set the polling frequency for any GpioInput.values streams. The default polling frequency is every 10 milliseconds. Pass null to turn off polling.

no getter, override

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

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.

inherited

dispose() → Future

Call dispose before exiting your application to cleanup native resources. Returns a future that completes when cleanup has finished.

override

input(int physicalPin, [Pull pull = Pull.off]) → GpioInput

Return a GPIO pin configured for input, where physicalPin is the physical pin number not the GPIO number.

override

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 physicalPin is the physical pin number not the GPIO number.

override

pwm(int physicalPin) → GpioPwm

Return a GPIO pin configured for software based PWM, where physicalPin is the physical pin number not the GPIO number.

override

testCmd(dynamic data) → void

For testing purposes only

throwPinAlreadyAllocated(int physicalPin) → void

override

toString() → String

A string representation of this object.

inherited

Operators

operator ==(Object other) → bool

The equality operator.

Static Methods

init({bool i2c = true, bool spi = true, bool eeprom = true, bool uart = true, Completer<GpioException>? onError, required dynamic isolateEntryPoint(SendPort sendPort), SendPort? testSendPort}) → Future<RpiGpio>

Instantiate a new GPIO manager. Clients should use initialize_RpiGpio.
