Detailed Description

Describes a Serial Wombat Pin. Is base class for other pin modes.

This class describes a Serial Wombat Pin on a Serial Wombat Chip. This class can be used to control a pin as a simple Digital I/O pin. This class is used as a base class for many other pin mode classes.

Digital I/O related members such as digitalWrite or pinMode should not be called against derived classes as this may have unpredicable effects on the state machines run by those derived classes.

Constructor & Destructor Documentation

SerialWombatPin() [1/2]

SerialWombatPin::SerialWombatPin ( SerialWombatChip &  serialWombatChip )

inline

Instantiates a Serial Wombat Pin.

Parameters

serialWombatChip

The chip on which the Serial Wombat Pin exists

SerialWombatPin() [2/2]

SerialWombatPin::SerialWombatPin ( SerialWombatChip &  serialWombatChip, uint8_t  pin  )

inline

Instantiates a Serial Wombat Pin.

Parameters

serialWombatChip	The chip on which the Serial Wombat Pin exists
pin	The pin number of the pin (WP number, not package pin number) of the pin

Member Function Documentation

digitalRead()

int SerialWombatPin::digitalRead ( )

inline

Reads the state of the Pin.

This function is based on the pin's public data, not a raw reading.

Returns

Returns LOW if pin is low or public data is 0. Returns HIGH if pin is high or public data is > 0

digitalWrite()

void SerialWombatPin::digitalWrite ( uint8_t  val )

inline

Set output pin High or Low.

Before calling this function, the pin should be configured as an input or output with pinMode()

Parameters

pin	The Serial Wombat pin to set. Valid values for SW4A: 0-3 SW4B: 1-3
val	Valid values are HIGH or LOW not use SW_INPUT, SW_HIGH or SW_LOW here, as these have different meanings

pin()

uint8_t SerialWombatPin::pin ( )

inline

Returns the current SW pin number. Used primarily for virtual calls by derived classes.

Returns

Returns the current SW pin number.

pinMode()

void SerialWombatPin::pinMode ( uint8_t  mode, bool  pullDown = false, bool  openDrain = false  )

inline

Set pin to INPUT or OUTPUT, with options for pull Ups and open Drain settings.

Parameters

mode	Valid values are INPUT, OUTPUT or INPUT_PULLUP as defined by arduino. Do not use SW_INPUT, SW_HIGH or SW_LOW here, as these have different meanings
pullDown	If True, a weak pull down will be enabled on this pin (No effect on SW4A/SW4B)
openDrain	If True, output becomes openDrain output rather than push / pull

readPublicData()

uint16_t SerialWombatPin::readPublicData ( )

inline

Read the 16 Bit public data associated with this pin.

Reads and returns the 16 bit value associated with this pin.

Returns

16 bit public data for this pin.

swPinModeNumber()

uint8_t SerialWombatPin::swPinModeNumber ( )

inline

Returns the Mode number. Used primarily by derived classes to populate packet data.

Returns

Returns the pin mode number

writePublicData()

uint16_t SerialWombatPin::writePublicData ( uint16_t  value )

inline

Write a 16 bit value to this pin.

Parameters

value

The 16 bit value to write
