Detailed Description

Interface for interrupt-driven button input.

Abstracts button press detection so that PedalLogic is independent of the concrete hardware ISR mechanism. Implementations live in the platform-specific hardware packages.

Member Function Documentation

event()

virtual bool IButton::event ( )

pure virtual

Checks for a button press event and clears the flag.

Returns

true if the button was pressed since the last call, false otherwise

Implemented in Button, and Button.

releaseEvent()

virtual bool IButton::releaseEvent ( )

inlinevirtual

Checks for a button release event and clears the flag.

Returns true exactly once per release edge (HIGH after press), then resets. Uses the ISR's awaitingRelease flag — safe to call from the main loop.

Reimplemented in Button, and Button.

Definition at line 45 of file i_button.h.

reset()

virtual void IButton::reset ( )

pure virtual

Resets the pressed flag.

Called before attaching interrupts to ensure no stale press is processed immediately after the interrupt handler is installed.

Implemented in Button, and Button.

setup()

virtual void IButton::setup ( )

pure virtual

Initializes the GPIO pin for button input.

Configures the pin as input with pull-up and any platform-specific GPIO setup required before interrupts can be attached.

Implemented in Button, and Button.
