 * @brief BATT Boost 2 Click example
 *
 * # Description
 * This library contains API for the BATT Boost 2 Click driver.
 * This driver provides the functions to control battery energy management 
 * device designed to maximize usable capacity from non-rechargeable.
 *
 * 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, 
 * sets the output voltage to 1.8V, charge current to 16mA, 
 * and early warning voltage to 2.6V.
 *
 * ## Application Task
 * This example demonstrates the use of the BATT Boost 2 Click board. 
 * The demo application uses two operations in two states: 
 * the charging state and the active state. First, when the device is in a Charge state, 
 * the external storage capacitor is charging from VBT using a constant current 
 * and displays storage capacitor voltage levels and charge cycle count.
 * Upon completion of a Charge state, the device transitions to the Active state 
 * at which time VDH becomes a regulated voltage output of 1.8V (default configuration), 
 * displays storage capacitor voltage level, and monitors alarms 
 * for low output voltage (below 1.8V) and early warning (below 2.4V). 
 * Results are being sent to the UART Terminal, where you can track their changes.
