使用BMP585和ATmega328P测量环境中的广泛气压

 * @file main.c
 * @brief Barometer 13 Click example
 *
 * # Description
 * This example demonstrates the use of  Barometer 13  Click board™ 
 * by reading and displaying the pressure and temperature measurements.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * The initialization of I2C or SPI module and log UART.
 * After driver initialization, the app sets the default configuration.
 *
 * ## Application Task
 * The demo application reads and displays the Pressure [mBar] and Temperature [degree Celsius] data.
 * Results are being sent to the UART Terminal, where you can track their changes.
