Class for making communication easier from code to i2c connected Rohm/Kionix sensors. Maybe could be used later also for abstracting Arduino/mbed os. Code ported from 'C'-library rohm-sensor-hal.

Dependents:   kionix-kx123-hello rohm-bh1790glc-hello simple-sensor-client rohm-SensorShield-example

Fork of rohm-sensor-hal by Rohm
