1、功能说明
  此例程提供了ADC单次转换的实现。
2、使用环境
    软件开发环境：KEIL MDK-ARM V5.26.2.0
    硬件环境：
        1、基于N32WB031_STB开发板
        2、MCU：N32WB031
3、使用说明 
    1、系统时钟：64MHz
    2、ADC通道：ADC_CTRL_CH_1(PB10)、ADC_CTRL_CH_3(PB8)
    日志打印：从模式 DEMO 板 PB6(TX)，波特率：115200
    测试步骤与现象：
        a，编译下载代码复位运行
        b，从串口看打印信息，验证结果两个通道ADC转换的电压
4、注意事项
    开发板的J15 短接右边，J16 短接左边，选择 IO 连接到排针。
