/**
* @ingroup tests
* @brief Test application for Vishay APDS99XX proximity and ambient light sensor
* @author Gunar Schorcht <gunar@schorcht.net>
* @file
*
* The test application demonstrates the use of the APDS99XX driver and
* polling the data every 200 ms.
*
* The application uses the following configurations:
*
* - 1 x ALS gain,
* - 64 steps as ALS integration time to use the full range of uint16_t,
* - 8 IR LED pulses at 100 mA current for proximity sensing,
* - 1 x proximity sensing gain, and,
* - no waits.
*
* Depending on the sensor, a measurement cycle takes from 156 ms (APDS9950)
* to 179 ms (APDS9960).
