 * @brief Charger 17 Click example
 *
 * # Description
 * This example demonstrates the use of Charger 17 click board by enabling battery charging and
 * displaying the charging status.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the click default configuration which enables charging.
 *
 * ## Application Task
 * Reads and displays the battery charging status (IC_STATUS and STAT0 regs) on the USB UART
 * approximately once per second.
