/*
* File: APDS9960.h
* Author: Nurul Syuhada @Cytron technologies Sdn. Bhd.
* Description: Has been modified from Arduino library:-
* @file SparkFun_APDS-9960.h
* @brief Library for the SparkFun APDS-9960 breakout board
* @author Shawn Hymel (SparkFun Electronics)
* to be used for PIC16F877A with gesture sensor.
* This library interfaces the APDS-9960 to SK40C over I2C. The library
* relies on the (I2C) library.
