chiggayeuh 0:49ae62548910 6 * @copyright This code is public domain but you buy me a beer if you use
chiggayeuh 0:49ae62548910 7 * this and we meet someday (Beerware license).
chiggayeuh 0:49ae62548910 8 *
chiggayeuh 0:49ae62548910 9 * This library interfaces the Avago APDS-9960 to Raspberry Pi over I2C. The library
chiggayeuh 0:49ae62548910 10 * relies on the wiringPi library. to use the library, instantiate an
chiggayeuh 0:49ae62548910 11 * APDS9960 object, call init(), and call the appropriate functions.
chiggayeuh 0:49ae62548910 12 *
chiggayeuh 0:49ae62548910 13 * APDS-9960 current draw tests (default parameters):
chiggayeuh 0:49ae62548910 14 * Off: 1mA
chiggayeuh 0:49ae62548910 15 * Waiting for gesture: 14mA
chiggayeuh 0:49ae62548910 16 * Gesture in progress: 35mA
