你好、Joseph casuga  

这里、我将 SOC 0取 为 A0、SOC 1取  为 A1、看到我只是打开 TI 为 ADC_ex1_SoC_SOFTWARE 提供的示例代码 、未在 SysConfig 中进行任何更改、然后使用 A0中连接的电位器信号/输出引脚读取 ADC、我正在旋转计数将0增加至4095 (myADC0Result0)。此处我将正确、但为什么另一个通道是解析、您可以提供原因  

此致、

// TITLE:  ADC Software Triggering

//! \addtogroup driver_example_list
//! <h1>ADC Software Triggering</h1>
//!
//! This example converts some voltages on ADCA and ADCC based on a software
//! trigger.
//!
//! The ADCC will not convert until ADCA is complete, so the ADCs will not run
//! asynchronously. However, this is much less efficient than allowing the ADCs
//! to convert synchronously in parallel (for example, by using an ePWM 
//! trigger).
//!
//! \b External \b Connections \n
//!  - A0, A1, C2, and C3 should be connected to signals to convert
//!
//! \b Watch \b Variables \n
//! - \b myADC0Result0 - Digital representation of the voltage on pin A0
//! - \b myADC0Result1 - Digital representation of the voltage on pin A1
//! - \b myADC1Result0 - Digital representation of the voltage on pin C2
//! - \b myADC1Result1 - Digital representation of the voltage on pin C3
