[IGSTK-Users] PolarisTracker problem on IGSTK[Problem Solved]

[Lin Qi]

>From the manual of Polaris Spectra, It seems to have to add INIT
command before the PHRQ to request a port handle for wireless tool.

so i add these code in the igstkPolarisTracker.cxx:

//INIT before PHRQ tested by Cruise
commandInterpreter->INIT();
if (this->CheckError(commandInterpreter) == FAILURE)
{
return FAILURE;
}
// end test

before the PHRQ command:
// request port handle using PHRQ
commandInterpreter->PHRQ("********", // device number
"*",        // TIU or SCU
"1",        // wireless
"**",       // port
"**");      // channel
if (this->CheckError(commandInterpreter) == FAILURE)
{
return FAILURE;
}

PolarisTrackerExample works well, the
"TrackerToolAttachmentToTrackerErrorEvent" disappeared, and can track
the tool position.

but i don't test  whether this would affect the part of wired tool or
the internal statemachine.

However, i am still confused Is this prolem related to the Firmware
version for polaris spectra?
