使用MAX11300和STM32F103RB体验最前沿的混合信号转换

/*!
 * \file 
 * \brief Pixi Click example
 * 
 * # Description
 * This example showcases how to initialize, configure and use the Pixi Click moduel. The Click
 * features Maxim Integrated's versatile, proprietary PIXI™ technology - the industry's first
 * configurable 20-channel mixed-signal data converter. 
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * This function initializes and configures the Click and logger modules. After the initial setup
 * a device id check is performed which will stop the module if the check fails. Additional con-
 * figurating is done in the default_cfg(...) function.
 * 
 * ## Application Task
 * This function sets the output signal on port 0 to different values every second.
