  This example shows the basic settings and functions for retrieving accelerometer
  data. Other possible Range settings, depending on your accelerometer KX132 or KX134, are
  the following:

  SFE_KX132_RANGE2G
  SFE_KX132_RANGE4G
  SFE_KX132_RANGE8G
  SFE_KX132_RANGE16G

  SFE_KX134_RANGE8G
  SFE_KX134_RANGE16G
  SFE_KX134_RANGE32G
  SFE_KX134_RANGE64G
