 This is an arduino IDE library to control the LSM6DS3.  It can be configured to use I2C or SPI with 2 instances per I2C channel or any number of SPI instances.  The top-level driver, class LSM6DS3, contains an inner driver LSM6DS3Core, a settings struct, and float-based math functions for conversion from raw to meaningful numbers.
 
-This has been tested with Arduino Uno and Teensy 3.1 architectures.
