请问F373系列如何使用HAL库配置SDADC？

在STM32CubeMX中很容易配置SDADC的。

没有用过，只能帮楼主加人气了。

受到警告

网上有教程的

STM32F373的SDADC编写过多通道数据采集
ADC_InitStructure.ADC_ScanConvMode = ENABLE;//扫描方式,这个一定要打开
ADC_RegularChannelConfig(ADC1, ADC_Channel_0 , 1, ADC_SampleTime_239Cycles5);
  ADC_RegularChannelConfig(ADC1, ADC_Channel_1, 2, ADC_SampleTime_239Cycles5);
设置好采集顺序，dma会先发送先采集的通道的数据，后发送后采集的通道的数据

太新。。。没用过。。。

楼主现在会配置了嘛
