使用LDC1041和ATmega328P重新定义感应和测量电感

/*!
 * @file main.c
 * @brief LDC2 Click example
 *
 * # Description
 * This example demonstrates the use of LDC 2 Click board.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and configures the Click board.
 *
 * ## Application Task
 * Measures the resonance impedance and proximity as well as the inductance and sensor frequency 
 * approximately every 200ms and displays all values on the USB UART.
