 * @file main.c
 * @brief Charger 25 Click example
 *
 * # Description
 * This example demonstrates the use of Charger 25 click board™ 
 * by enabling battery charging and displaying battery voltage and charging status.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialization of I2C module and log UART.
 * After driver initialization, the app executes a default configuration.
 *
 * ## Application Task
 * The demo application reads and displays the results of the battery voltage, 
 * minimal system voltage, battery voltage limit and charging status.
 * Results are being sent to the UART Terminal, where you can track their changes.
 * 
 * ## Additional Function
 * - static void charger25_display_status ( void )
