 * @file main.c
 * @brief LED Driver 15 Click example
 *
 * # Description
 * This example demonstrates the use of LED Driver 15 Click board by changing
 * the LEDs dimming level.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the Click default configuration.
 *
 * ## Application Task
 * Changes the LEDs dimming level in I2C mode every 500ms. The dimming level will be
 * displayed on the USB UART.
 *
 * @note
 * It is recommended to connect 8 LEDs in series (40mA) to the output connector.
