使用ADC1283和PIC32MZ1024EFH064实现模拟信息在数字系统中的高效传输

/*!
 * @file main.c
 * @brief ADC 21 Click example
 *
 * # Description
 * This example demonstrates the use of ADC 21 click board by reading and displaying
 * the voltage levels from 8 analog input channels.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and logger.
 *
 * ## Application Task
 * Reads the voltage levels from all 8 analog input channels and displays the results
 * on the USB UART once per second approximately.
