使用LTC1968和STM32F446RE将输入信号的RMS转换为稳定的直流电压

/*!

 * \brief RmstoDc Click example
 * 
 * # Description
 * This application convert the RMS of the input signal into a DC voltage.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes I2C interface and turns ON the device.
 * 
 * ## Application Task  
 * Reads DC output voltage calculated to mV and
   sends results to the serial terminal.
 * 
 * Note : The input voltage frequency should be in the range from 50Hz to 250kHz.
 * Also the input voltage amplitude must be lower than 5V.
 * In this conditions the device can convert the RMS signal, in every form, to DC signal.
