Public Member Functions

 vrpn_Tracker_Isotrak (const char *name, vrpn_Connection *c, const char *port="/dev/ttyS1", long baud=19200, int enable_filtering=1, int numstations=vrpn_ISOTRAK_MAX_STATIONS, const char *additional_reset_commands=NULL)
 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/ttyS1 (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 Fastrak (default 4). The station select switches on the front of the Fastrak 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 Fastrak manual for a list of these. There can be multiple lines of them but putting <CR> into the string.

Constructor & Destructor Documentation

◆ vrpn_Tracker_Isotrak()

vrpn_Tracker_Isotrak::vrpn_Tracker_Isotrak ( const char * name,
vrpn_Connection * c,
const char * port = "/dev/ttyS1",
long baud = 19200,
int enable_filtering = 1,
int numstations = vrpn_ISOTRAK_MAX_STATIONS,
const char * additional_reset_commands = NULL )

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/ttyS1 (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 Fastrak (default 4). The station select switches on the front of the Fastrak 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 Fastrak manual for a list of these. There can be multiple lines of them but putting <CR> into the string.
