App hangs after a while

[ulitiy]

Hi! I'm using your example but it hangs on Vector raw = compass.readRaw(); after 2-5 minutes if I'm using 1m UTP cable. If direct connection - everything ok. What can you recommend?

UPD: the reason for that is infinite loop in readRegister16 depending on !Wire.available()
So some fail safe could be added. I patched it like

    if(!Wire.available()) {
      while (!begin())
      {
        Serial.println("Could not find a valid HMC5883L sensor, check wiring!");
        delay(100);
      }
      return 0;
    }

But the wire lib doesn't provide fail safe in it's Wire.endTransmission(); so if the power is lost for a second it won't recover too. So maybe should use another I2C lib with timeout support.
