使用A3908和ATmega644P确保最精细的运动控制

 * @file main.c
 * @brief DC Motor 25 Click example
 *
 * # Description
 * This example demonstrates the use of DC Motor 25 click board™
 * by driving the DC motor in both directions every 3 seconds.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the I2C driver and performs the click default configuration.
 *
 * ## Application Task
 * This example demonstrates the use of the DC Motor 25 Click board™.
 * Drives the motors in the forward and reverse direction 
 * with a 3 seconds delay with engine braking between direction changes.
 * Results are being sent to the UART Terminal, where you can track their changes.
