使用 ILPS22QS 和 STM32F031K6 平稳监测大气压力

 * @brief Barometer8 Click example
 *
 * # Description
 * This example demonstrates the use of Barometer 8 Click board by reading and
 * displaying the pressure and temperature values.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the Click default configuration.
 *
 * ## Application Task
 * Reads and displays the pressure and temperature data on the USB UART every 250ms approximately,
 * as per output data rate (ODR) bits configuration.
