 * @brief LEDDriver9 Click example
 *
 * # Description
 * This app demonstrates the configuration and control
 * of the LED Driver 9 click board resulting in a nice
 * breathing effect.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * The initialization configures the UART LOG and I2C
 * drivers and adjusts the Led Driver 9 click general
 * register settings.
 *
 * ## Application Task
 * The application task is a simple breathing effect on
 * all LED out channels.
