Detailed Description

A component that implements reset button functionality.

On short press, it will cause component loop to return false, then ksAppRotator will move to the next application. On long press, it will erase user data (factory reset).

The component has also built-in debounce handling logic.

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 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 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.
