/************************************************
ALIENTEK 战舰AT32F403开发板实验
ADC 实验（ADC1/2/3同时使用）
说明1：ADC1和ADC2采用同步规则模式，
说明2：ADC配置为扫描模式、非连续转换、软触发、右对齐、使用DMA模式、通道采样时间1.5个周期
说明3：ADC1规则组定义两个通道（通道0、通道2），ADC2定义两个通道（通道1、通道3）
说明4：ADC1通过DMA1的通道1传输数据，ADC2利用双ADC由ADC1的DMA1的通道1传输数据，
说明5：所有ADC转换数据均在DMA1传输完成中断内进行打印
