使用MIC74和STM32F446RE实现风扇速度的魔法控制

/*!
 * \file 
 * \brief Fan3 Click example
 * 
 * # Description
 * This application controls the fan speed.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes the Click device.
 * 
 * ## Application Task  
 * Cycles through different fan speeds, including 0 - stopped.
