Experience a new level of environmental monitoring with ICP-10125 and ATmega328P

/*!
 * @file main.c
 * @brief Barometer 12 Click example
 *
 * # Description
 * This library contains API for the Barometer 12 Click driver.
 * The library initializes and defines the I2C bus drivers 
 * to write and read data from registers.
 * This demo application shows an example of 
 * atmospheric pressure and temperature measurement.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * The initialization of the I2C module and log UART.
 * After driver initialization and default settings, 
 * the app display device ID.
 *
 * ## Application Task
 * This is an example that shows the use of a Barometer 12 Click board™.
 * Logs the atmospheric pressure [ Pa ] and temperature [ degree Celsius ] data.
 * Results are being sent to the Usart Terminal where you can track their changes.
