Krishan Bhagat / APDS_9960

APDS-9960 Light, RGB, Proximity, and Gesture Sensor https://www.sparkfun.com/products/12787 This library interfaces the APDS-9960 to Mbed over I2C. The library relies on the I2C library. To use the library, instantiate a glibr object, call ginit(), and call the appropriate functions.

Dependents:   Gesture_User_Interface car_test_v1 Capt_couleur_CAN Capt_couleur_smart
