使用LPS27HHW和STM32F302VC像专业人士一样管理和优化压力数据

 * @file main.c
 * @brief Pressure15 Click example
 *
 * # Description
 * This application example showcases the ability of the device to
 * read temperature and pressure data.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialization of hosts communication modules (UART, SPI/I2C) 
 * and interrupt pin. Checks device ID and sets the default configuration
 * that enables interrupt on new data.
 *
 * ## Application Task
 * Checks if an interrupt occurred. If occurred reads new pressure and temperature
 * data in hPa and degC respectively.
