使用LPS22HB和ATmega1284体验气压测量的未来

/*!
 * \file 
 * \brief Lps22hb Click example
 * 
 * # Description
 * The demo application measures temperature and pressure.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initalizes click driver, resets the device, applies default settings
 * and makes an initial log.
 * 
 * ## Application Task  
 * This is a example which demonstrates the use of LPS22HB Click board. By 
 * measuring temperature and pressure. The results are being sent to the USART 
 * terminal where you can track their changes.
