构造及析构函数说明

vrpn_Tracker_Liberty()

vrpn_Tracker_Liberty	(	const char *	name,
		vrpn_Connection *	c,
		const char *	port = "/dev/ttyS0",
		long	baud = 115200,
		int	enable_filtering = 1,
		int	numstations = vrpn_LIBERTY_MAX_STATIONS,
		const char *	additional_reset_commands = NULL,
		int	whoamilen = 195 )

The constructor is given the name of the tracker (the name of the sender it should use), the connection on which it is to send its messages, the name of the serial port it is to open (default is /dev/ttyS0 (first serial port in Linux)), the baud rate at which it is to communicate (default 19200), whether filtering is enabled (default yes), and the number of stations that are possible on this Liberty (default 4). The station select switches on the front of the Liberty determine which stations are active. The final parameter is a string that can contain additional commands that are set to the tracker as part of its reset routine. These might be used to set the hemisphere or other things that are not normally included; see the Liberty manual for a list of these. There can be multiple lines of them but putting <CR> into the string.

成员函数说明

add_stylus_button()

int add_stylus_button	(	const char *	button_device_name,
		int	sensor,
		int	numbuttons = 1 )

Add a stylus (with button) to one of the sensors.

get_report()

virtual int get_report ( void )

protectedvirtual

report_length()

int report_length ( int sensor )

protected

Augments the basic Liberty report length

reset()

virtual void reset ( )

protectedvirtual

Reset the tracker.

实现了 vrpn_Tracker_Serial.

set_sensor_output_format()

int set_sensor_output_format ( int sensor )

protected

Augments the basic Liberty format
