使用AS3935和PIC18F57Q43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  
 * Always checks is interrupt event happend (Listening mode) and 
 * after that gets the informations about storm. Results logs on UART.
 *
