使用AD7124-8和STM32F302VC将现实世界的物理量转换为数字数据

/*!
 * @file main.c
 * @brief ISO ADC 6 Click example
 *
 * # Description
 * This example demonstrates the use of the ISO ADC 6 Click board™ 
 * by reading and writing data by using SPI serial interface 
 * and reading results of AD conversion.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialization of SPI module and log UART.
 * After driver initialization, the app executes a default configuration which enables channel 0,
 * puts A0 on positive analog input and A1 on negative analog input,
 * enables internal reference voltage (approximately 2.65V (AVDD = 3.3V)),
 * and also enables bipolar operation mode and puts device on full power mode.
 *
 * ## Application Task
 * The demo application reads the voltage levels from analog input (A0-A1) and displays the results.
 * Results are being sent to the UART Terminal, where you can track their changes.
