使用BME280和PIC18F26K40精确监测和控制室内气候条件

 * @brief Weather Click example
 * 
 * # Description
 * This demo-app shows the temperature, pressure and humidity measurement using Weather Click.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Configuring Clicks and log objects.
 * Setting the Click in the default configuration to start the measurement.
 * 
 * ## Application Task  
 * Reads Temperature data, Relative Humidity data and Pressure data, 
 * and displays them on USB UART every 1500ms.
