使用MCP3204和STM32L496AG设立多功能测试的新标准

/*!
 * \file 
 * \brief Multimeter Click example
 * 
 * # Description
 * This example showcases how to configure, initialize and use the Multimeter Click. The
 * Click measures resistance in Ohms, voltage in mVs, current in mAs and capacitance in nFs
 * using a dual CMOS and quad CMOS op-amps, an ADC and other on board modules.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * This function initializes and configures the logger and Click modules. Additional 
 * calibration of the measurement components is done in the default_cfg(...) function.
 * 
 * ## Application Task  
 * This function measures and displays resistance, voltage, current and capacitance data.
 * It does so every second.
