title: I got a error sensoring with L3GD20 in Raspberry pi 2B
body: <p>I am creating a mobile robot, so I am using Raspberry Pi with Adafruit_I2C library, so I need to get Axis Z degree, the idea is to determine the angle when turning in a curve.
  Code:
      def read(self):</p>
  
  <pre><code>    # Read gyro values
      list = self.gyro.readList(self.L3GD20_REGISTER_OUT_X_L | 0x80, 6)
      res = [(self.gyro16(list, 0)*self.sensitivity,
              self.gyro16(list, 2)*self.sensitivity,
              self.gyro16(list, 4)*self.sensitivity )]
  
      return res
  </code></pre>
  
  <p>The error is this:</p>
  
  <pre><code>Traceback (most recent call last):
   File "L3GD20.py", line 119, in &lt;module&gt;
     print l3.read()
   File "L3GD20.py", line 104, in read
    res = [(self.gyro16(list, 0)*self.sensitivity, 
   AttributeError: 'L3GD20' object has no attribute 'sensitivity'
  </code></pre>
  
  <p>Someone knows how to fix this problem?? Thanks!!</p>
