Detailed Description

Class that runs on top of SerialWombatMatrixKeypad to treat a key as an individual button.

This class allows a single key from a SerialWombatMatrixKeypad to be treated as an individual SerialWombatAbstractButton that can be read as such or passed to SerialWombatButtonCounter .

Constructor & Destructor Documentation

SerialWombatMatrixButton()

SerialWombatMatrixButton::SerialWombatMatrixButton ( SerialWombatMatrixKeypad & kp, uint8_t keyIndex )

inline

Instantiate a SerialWombatMatrixButton.

Parameters

kp	An initialized SerialWombatMatrixKeypad
keyIndex	a number 0-15 indicating which key (index, not ascii value) is treated as a button

Member Function Documentation

digitalRead()

bool SerialWombatMatrixButton::digitalRead ( )

inlinevirtual

Returns the state of the input.

This function reads from the public data of the pin which indicates the state of the input

Returns

TRUE for pressed or FALSE.

Implements SerialWombatAbstractButton.

Definition at line 415 of file SerialWombatMatrixKeypad.h.

readDurationInFalseState_mS()

uint16_t SerialWombatMatrixButton::readDurationInFalseState_mS ( )

inlinevirtual

return the number of mS that the button has been in false state

Returns

returns a value in mS which saturates at 65535. Returns 0 if currently true.

Implements SerialWombatAbstractButton.

Definition at line 438 of file SerialWombatMatrixKeypad.h.

readDurationInTrueState_mS()

uint16_t SerialWombatMatrixButton::readDurationInTrueState_mS ( )

inlinevirtual

return the number of mS that the button has been in true state

Returns

returns a value in mS which saturates at 65535. Returns 0 if currently false.

Implements SerialWombatAbstractButton.

Definition at line 464 of file SerialWombatMatrixKeypad.h.

readTransitionsState()

bool SerialWombatMatrixButton::readTransitionsState ( )

inline

Queries the number of transistions that have occured on the button.

This function queries the button for current state and transitions since last call. transition count is put in the global member transitions. The keypad driver in the Serial Wombat chip resets its count to zero after this call.

Returns

TRUE or FALSE, current status of debounced input
