使用PAC1720和MK64FN1M0VDC12深入了解能耗模式

/*!
 * @file main.c
 * @brief PAC1720 Click example
 *
 * # Description
 * This example demonstrates the use of PAC1720 click board by reading the voltage, 
 * current, and power from both available channels.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the click default configuration.
 *
 * ## Application Task
 * Reads the voltage, current, and power from both channels and displays 
 * the results on the USB UART approximately once per second.
