 * @brief BarGraph 5 Click example
 *
 * # Description
 * This example demonstrates the use of BarGraph 5 click board by changing
 * the level of all BarGraph output channels.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the click default configuration.
 *
 * ## Application Task
 * Changes the level of all BarGraph channels once per second.
 * The channels level is displayed on the USB UART.
