使用STUSB4500和ATmega328体验闪电般快速的电力/数据共享

/*!
 * @file main.c
 * @brief USBCSink Click example
 *
 * # Description
 * This is an example which demonstrates the use of USB-C Sink Click board.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialization driver enables - I2C,
 * set hw reset, set PDO2 profile and current value for PDO2 1.5A,
 * upload new data and reset device to write NVM settings to the STUSB450,
 * also write log.
 *
 * ## Application Task
 * USB-C Sink Click board can be used to read the Power Data Objects (PDO) 
 * highest priority profile:
 * PDO1 :  5V,
 * PDO2 : 12V,
 * PDO3 : 20V.
 * All data logs write on USB uart changes for every 5 sec.
