使用DPS310和PIC18F4550获取实时、可靠的压力数据

/*!
 * \file 
 * \brief Pressure3 Click example
 * 
 * # Description
 * This application is digital barometric pressure sensor.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initialization device, set default configuration and start to write log.
 * 
 * ## Application Task  
 * This is an example which demonstrates the use of Pressure 3 Click board.
     Measured pressure and temperature data from the DPS310 sensor on Pressure 3 Click board.
     Results are being sent to the Usart Terminal where you can track their changes.
     All data logs write on usb uart changes for every 3 sec.
