Deliver measurements of current, voltage, power, and temperature with the TSC1641 and ATmega2560

/*!
 * @file main.c
 * @brief Current 12 Click example
 *
 * # Description
 * This example demonstrates the use of the Current 12 Click board 
 * by reading and displaying the input current measurements.
 *
 * 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 current, voltage, and power measurements.
 * Results are being sent to the UART Terminal, where you can track their changes.
