通过结合V1000和STM32F031K6重新定义音质，带来最佳音频体验

/*!
 * @file main.c
 * @brief DSP Click Example.
 *
 * # Description
 * This application controls reverb and multi-effects Digital Multi-Effects DSP 
 * provides different sound performance of the DSP Click.  
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes GPIO driver, set the default configuration and start to write log.
 *
 * ## Application Task
 * This is an example that shows the use of a DSP click board.
 * In this example, we change different sound effects
 * such as multiple reverbs, echo, phaser, chorus, flanger, etc. every 10 sec.
 * Results are being sent to the Usart Terminal where you can track their changes.
