STM32_ADC_DMASTM32的每个ADC模块通过内部的模拟多路开关，可以切换到不同的输入通道并进行转换。STM32特别地加入了多种成组转换的模式，可以由程序设置好之后，对多个模拟通道自动地进行逐个地采样转换。-STM32_ADC_DMASTM32 Each ADC module through an internal analog multiplexer switch, you can switch to different input channels and convert. STM32 particular group to join a variety of conversion into the model, the program can be set up, on a number of analog channels to be automatically converted one by one sample.
