使用AS3935和ATmega328P提供精确的雷电活动检测

/*!
 * @file 
 * @brief Thunder Click example
 * 
 * # Description
 * This application detects the presence and proximity of potentially 
 * lightning activity and provides estimated distance to the center of the storm. 
 * It can also provide information on the noise level.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes SPI driver and performs the reset command and RCO calibrate command.
 * Also configures the device for working properly.
 * 
 * ## Application Task  
 * Checks if the interrupt event has occured (Listening mode) and after that reads
 * the storm information and logs the results on the USB UART.
