 * @file main.c
 * @brief Charger 27 Click Example.
 *
 * # Description
 * This example demonstrates the use of the Charger 27 Click board 
 * by enabling charge or discharge mode and 
 * indicating valid input supply and charging completion.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialization of GPIO module and log UART.
 * After driver initialization, the app sets charge mode.
 *
 * ## Application Task
 * The Charger 27 Click board operates as a switching charger to charge a 1S battery 
 * from a wide input power range of 5V to 16V, which can cover a USB PD voltage level.
 * The demo application checks and displays the charging completion indicator status.
 * Results are being sent to the UART Terminal, where you can track their changes.
