 * @file main.c
 * @brief Illuminance Click example
 *
 * # Description
 * This example demonstrates the use of Illuminance Click board by reading
 * and displaying the RAW channels data measurements.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the Click default configuration.
 *
 * ## Application Task
 * Waits for the data ready interrupt, then reads the RAW channels data measurements
 * and displays the results on the USB UART. By default, the data ready interrupt triggers 
 * upon every ADC cycle which will be performed every 200ms.
