Unlock the potential of precise energy monitoring using PAC1934 and STM32F031K6

/*!
 * \file 
 * \brief Pac1934 Click example
 * 
 * # Description
 * This application measures the voltage.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initalizes device, enables the device and makes an initial log.
 * 
 * ## Application Task  
 * This is an example that shows the most important
 * functions that PAC1934 Click has, it mesures voltage, current, power and energy.
