 * @brief LED Driver 17 Click example
 *
 * # Description
 * This example demonstrates the use of LED Driver 17 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 by setting the PWM duty cycle every 500ms. 
 * The duty cycle percentage will be displayed on the USB UART. It also checks
 * the fault indication pin and displays it accordingly.
