 * @brief Charger 19 Click Example.
 *
 * # Description
 * This example demonstrates the use of Charger 19 Click board by enabling the device
 * and then reading and displaying the battery voltage.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and enables the device, sets the output 
 * voltage to 3 V.
 *
 * ## Application Task
 * Tracking charging status, reading battery voltage.
