 4   *  This is a library for the Adafruit LIS331HH Accel breakout board
 5   *
 6   *  Designed specifically to work with the [Adafruit LIS331HH Triple-Axis
 7   * Accelerometer (+-6g/12g/24g)](https://www.adafruit.com/product/4XXX)
 8   *
 9   *  This sensor communicates over I2C or SPI (our library code supports both) so
10   * you can share it with a bunch of other sensors on the same I2C bus.
11   *
12   *  Adafruit invests time and resources providing this open source code,
13   *  please support Adafruit andopen-source hardware by purchasing products
14   *  from Adafruit!
