使用LT5581和PIC32MZ2048EFH100测量RF信号强度

 * @file main.c
 * @brief RF Meter 3 Click Example.
 *
 * # Description
 * This example demonstrates the use of RF Meter 3 click board.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and enables the click board.
 *
 * ## Application Task
 * Measures the RF input signal power in dBm and displays the results on the USB UART every 100ms.
