 * @file main.c
 * @brief BarGraph4 Click example
 *
 * # Description
 * This example demonstrates the use of BarGraph 4 click board.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and enables output.
 *
 * ## Application Task
 * Changes the level of all bar graph channels every second.
 * The channels level will be logged on the USB UART.
