 * @brief VCP Monitor 6 Click example
 *
 * # Description
 * This library contains API for the VCP Monitor 6 Click driver 
 * for measurements of the voltage, current, power, energy, charge, and die temperature.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * The initialization of the I2C module and log UART.
 * After driver initialization, the app sets the default configuration.
 *
 * ## Application Task
 * The demo application reads and displays the results of the input bus voltage, 
 * current, power, energy, charge accumulation measurements, and die temperature.
 * Results are being sent to the UART Terminal, where you can track their changes.
