Experience a new level of precision in force measurement using FMAMSDXX025WC2C3 and ATmega328P

/*!
 * @file main.c
 * @brief Force5 Click example
 *
 * # Description
 * This is an example that demonstrates the use of the Force 5 Click board.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialization driver enables - I2C,
 * calibration the device, display diagnostic states and temperature.
 *
 * ## Application Task
 * Force 5 Click board is measuring force ( N ).
 * All data logs write on USB uart changes every 500 milliseconds.
