Detailed Description

Normalized board input events and button state.

The BSP supplies physical pin assignments and polarity; this interface exposes product-relative buttons and normalized events. As a result, apps never need to poll GPIO numbers or know whether a switch is active low.

Member Function Documentation

hasPendingEvents()

virtual bool ersa::hal::IInput::hasPendingEvents ( ) const

pure virtual

Report queued normalized input events that still need application dispatch.

init()

virtual Result< void > ersa::hal::IInput::init ( )

pure virtual

Configure board pins, debounce state, and event publication.

isPressed()

virtual bool ersa::hal::IInput::isPressed ( events::ButtonId  button ) const

pure virtual

Query current debounced state using a logical ButtonId.

poll()

virtual void ersa::hal::IInput::poll ( )

pure virtual

Sample/debounce physical controls and post resulting events. Call regularly from the application task; hardware callbacks should not call app code directly.
