使用BME680和PIC18F25K50体验全新的环境洞察

/*!
 * \file 
 * \brief Environment Click example
 * 
 * # Description
 * Example demonstrates use of the Environment Click board.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initialization driver enables - Device software reset, check device ID, set default configuration of BME680 chip, also display logs.
 * 
 * ## Application Task  
 * This is an example which demonstrates the use of Environment Click board.
 * Measures temperature, humidity, pressure and gas resistance data from the BME680 chip sensor.
 * Displays ambient temperature data [ degrees Celsius ],
 * humidity data [ % ], pressure data [ mbar ] and gas resistance.
 * Results are being sent to the Usart Terminal where you can track their changes.
 * All data logs write on usb uart changes for every 2 sec.
