Public Member Functions
	ORG4400 (SerialPort &uart, int8_t pinOnOff, int8_t pinWakeup)
	Bind UART, on/off output pin, and wakeup-status input pin.
void	begin ()
	Configure 4800-baud reception and GPIO; listen if the receiver is already on.
void	onReadDone (void(*func)(int32_t latitude, int32_t longitude, int32_t altitude, uint8_t numSatellites))
	Register the legacy position callback; nullptr disables notification.
void	turnOn ()
	If off, enable reception and pulse the hardware on/off pin.
void	turnOff ()
	If on, pulse the hardware on/off pin and stop UART input/listening.
bool	isOn ()
	Return true when the receiver wakeup-status pin is high.
Public Member Functions inherited from Gps
void	onReadDone (void(*func)(uint8_t fixQuality, uint8_t hour, uint8_t minute, uint8_t sec, uint16_t subsec, int32_t latitude, int32_t longitude, int32_t altitude, uint8_t numSatellites))
	Register the GGA callback; nullptr disables legacy GGA notifications.

Additional Inherited Members
Public Attributes inherited from Gps
void(*	onNMEAReceived )(Gps &) = nullptr
	Optional raw-NMEA notification used by MT3339 after receiving VTG. Invoked only when no onReadDone() callback is installed; read cached sentences during the callback because most caches are cleared immediately afterward.

Member Function Documentation

isOn()

bool ORG4400::isOn ( )

virtual

Return true when the receiver wakeup-status pin is high.

Implements Gps.

onReadDone()

void ORG4400::onReadDone

(

void(*

func )(int32_t latitude, int32_t longitude, int32_t altitude, uint8_t numSatellites)

)

Register the legacy position callback; nullptr disables notification.

Parameters

func	Receives encoded latitude, longitude, altitude, and satellite count. The legacy parser combines integer and fractional fields with bitwise OR (coordinate integer parts are multiplied by 10000, altitude by 10) and ignores hemisphere indicators. Values must not be treated as signed decimal degrees.

turnOff()

void ORG4400::turnOff ( )

virtual

If on, pulse the hardware on/off pin and stop UART input/listening.

Implements Gps.

turnOn()

void ORG4400::turnOn ( )

virtual

If off, enable reception and pulse the hardware on/off pin.

Implements Gps.
