 It may be appropriate to build mappings of pin directions (input, output), pullups (up, down, off) and interrupt edges (rising, falling, both) if appropriate for this hardware. The base GenericGPIO class uses its own constants to refer to these, so the mappings translate the base GenericGPIO's constants to ones used by the hardware's Python library.

 If a digital input is not configured as an [interrupt](config/interrupts.md) (or even [sometimes if it is](config/reference/digital_inputs/?id=digital_inputs-star-interrupt_for)), then a loop will be created which polls the pin's current value and publishes a `DigitalInputChangedEvent` event when it does.
