 * \brief Balancer5 Click example
 * 
 * # Description
 * This example demonstrates basic Balancer 5 Click functionalities.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes Click and Driver, Checks Device ID, starts charging,
 * reads charge status registers and configures ADC.
 * 
 * ## Application Task  
 * Reads ADC values from registers and logs it.
 * 
 * ## Additional function
 * void charger_status_1_handler ( uint8_t cs1_data );
 * void charger_status_2_handler ( uint8_t cs2_data );
