使用LTC2500-32和STM32F302VC实现尖端A/D转换

/*!
 * \file 
 * \brief ADC7 Click example
 * 
 * # Description
 * This application collects data from the analog signal, calculates and logs the
 * converted voltage value.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes driver and performs configuration for conversion cycles.
 * 
 * ## Application Task  
 * Performs the determined number of conversion cycles which are necessary for averaging. 
 * When all conversion cycles are done, it reads the converted voltage value.
 * Results will be logged on UART terminal every second.
