 * @brief 4x4 RGB 2 Click example
 *
 * # Description
 * This example demonstrates the use of 4x4 RGB 2 click board by setting all 16 LEDs
 * to different colors and changing the LEDs color every 500 milliseconds. 
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the click default configuration which sets
 * the LEDs brightness to level 1 and the color to black (all LEDs off).
 *
 * ## Application Task
 * Sets all 16 LEDs to a different colors and changes their color every 500 milliseconds.
 * All data is displayed on the USB UART where you can track their changes.
