Member Function Documentation

autoDetectPortName()

QString PolhemusConnection::autoDetectPortName ( )

static

Best-effort auto-detection of an attached Fastrak/FastSCAN.

Polhemus Fastrak/FastSCAN units ship with an FTDI USB-serial bridge (vendor id 0x0F44 for newer Polhemus-branded units, 0x0403 for the generic FTDI chip used in older units). This scan returns the first matching port name, or an empty string if no candidate is found.

Definition at line 126 of file polhemus_connection.cpp.

availablePorts()

QStringList PolhemusConnection::availablePorts ( )

static

Enumerate every serial port currently visible to the OS.

Convenience wrapper around QSerialPortInfo::availablePorts that returns just the system port names (e.g. /dev/cu.usbserial-AB0, COM3) so callers can populate a combo box without pulling in QSerialPortInfo themselves.

Definition at line 115 of file polhemus_connection.cpp.

backendName()

QString PolhemusConnection::backendName

(

)

const

Definition at line 106 of file polhemus_connection.cpp.

close()

void PolhemusConnection::close

(

)

Close the active connection. Safe to call when already closed.

Definition at line 84 of file polhemus_connection.cpp.

connectedChanged

void UTILSLIB::PolhemusConnection::connectedChanged ( bool isConnected )

signal

Emitted whenever isConnected changes.

errorOccurred

void UTILSLIB::PolhemusConnection::errorOccurred ( const QString & message )

signal

Non-fatal protocol/IO error (already logged by the backend).

isConnected()

bool PolhemusConnection::isConnected

(

)

const

Definition at line 101 of file polhemus_connection.cpp.

open()

bool PolhemusConnection::open	(	const QString &	portName,
		const PolhemusSerialConfig &	cfg = PolhemusSerialConfig{} )

Open the connection.

Parameters

portName	Empty → mock backend. Non-empty → hardware backend.
cfg	Serial transport configuration; ignored by the mock backend.

Definition at line 57 of file polhemus_connection.cpp.

penButtonPressed

void UTILSLIB::PolhemusConnection::penButtonPressed ( int station, const QVector3D & position, const QQuaternion & orientation )

signal

Emitted when the continuous stream pauses (pen button pressed). The last received position/orientation are provided so the caller can record the capture without a separate GUI button click.

After emitting, the connection automatically restarts the continuous stream so the live feed resumes on button release.

pointReceived

void UTILSLIB::PolhemusConnection::pointReceived ( int station, const QVector3D & position, const QQuaternion & orientation )

signal

Parameters

station	Polhemus station id (1..4 for FastSCAN).
position	Sample point in metres, sensor-frame.
orientation	Sensor orientation; identity if N/A.
