Detailed Description

A component that implements reset button functionality.

On a short press, the component loop returns false, prompting ksAppRotator to switch to the next application. On a long press, it performs a factory reset by erasing user data.

The component also includes built-in debounce handling.

Constructor & Destructor Documentation

ksResetButton()

ksf::comps::ksResetButton::ksResetButton	(	uint8_t	pin,
		uint8_t	triggerState,
		uint8_t	mode )

Constructs the reset button component.

Parameters

pin	Pin number assigned to the button.
triggerState	Pin state that triggers the reset logic (LOW or HIGH).
mode	Pin mode (INPUT / INPUT_PULLUP etc).

Member Function Documentation

getInstanceType()

virtual const std::size_t ksf::comps::ksResetButton::getInstanceType ( ) const

inlinevirtual

Retrieves type ID of the object.

Returns

Object type ID.

Reimplemented from ksf::ksComponent.

getPin()

uint8_t ksf::comps::ksResetButton::getPin ( ) const

inline

Retrieves pin number assigned to the button.

Returns

Pin number assigned to the reset button.

References pin.

init()

bool ksf::comps::ksResetButton::init ( ksApplication * app )

overridevirtual

Initializes the reset button component.

Parameters

app	Pointer to the parent ksApplication.

Returns

True on success, false otherwise.

Reimplemented from ksf::ksComponent.

References lastState, mode, and pin.

isA()

virtual bool ksf::comps::ksResetButton::isA ( const std::size_t id ) const

inlinevirtual

Checks whether object is of given type.

Parameters

id	Type ID to check against.

Returns

True if object is of given type, otherwise false.

Reimplemented from ksf::ksComponent.

loop()

bool ksf::comps::ksResetButton::loop ( ksApplication * app )

overridevirtual

Handles the reset button component logic.

Parameters

app	Pointer to the parent ksApplication.

Returns

True on success, false otherwise.

Reimplemented from ksf::ksComponent.

References lastState, pin, pressedTime, releasedTime, and triggerState.
