使用TS2007FC和STM32F302VC释放卓越音频的力量

 * @brief AudioAMP 12 Click Example.
 *
 * # Description
 * This example demonstrates the use of AudioAMP 12 Click board™. 
 * The library contains an API for switching between two gain settings 
 * and device control selection between operation and standby mode.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialization of GPIO module and log UART. After driver initialization, 
 * the app sets default settings performs a power-up sequence, and sets the sound volume to 6 dB.
 *
 * ## Application Task
 * The app performs circles the volume switch between two gain settings, 
 * 6 dB or 12 dB, every 5 seconds. 
 * Results are being sent to the UART Terminal, where you can track their changes.
