solving hangup of the sensor (in continuous mode)

[Stef-aap]

sometimes the sensor hangs, resetting or init doesn´t solve the problem. There are 2 ways to solve the problem:

1. powercycle the sensor
2. modify the Data_Ready method as shown below

bool QMC5883LCompass::Data_Ready () {
Wire.beginTransmission ( _ADDR ) ;
Wire.write ( 0x06 ) ;
int err = Wire.endTransmission();
if (!err) {
Wire.requestFrom(_ADDR, (byte)1);
uint8_t Status = Wire.read() ;
if ( ( Status & 0x01 ) > 0 ) return true ;

// *********************************************************************
//SM: to prevent hangup, if skipbit DOR (0x04) is set
// youe to perform a read to get it working again (but data will be invalid)
if ( ( Status & 0x04 ) > 0 ) read() ;
// *********************************************************************

}
return false ;
}

I can't find this Data_Ready function anywhere.

where is this data_Ready function?
