使用ADC121S021和TM4C1299NCZAD实现模拟信号的精确数字表示

/*!
 * \file 
 * \brief ADC5 Click example
 * 
 * # Description
 * This example showcases how to initialize and configure the logger and click modules and 
 * how to read and display ADC voltage data from the click.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * This function initializes and configures the logger and click modules. 
 * 
 * ## Application Task  
 * This function reads and displays ADC voltage data every second.
