问：自己配置单独的injected通道是可以的，使用DMA始终不能正常工作。
答：自问自答好了，DMA通道没有配置对。
回答时间：答：楼主能否发一份多通道的初始化程序给我。不胜感激，我已经困惑好久了，先谢谢了！
回答时间：答：如果用了两路SDADC ,Dma 数据要设置32位传输长度。还有，对照查找SDADC 对应的DMA 通道

STM32F373:SDADC1、2、3三路多通道+DMA采集电压
主题帖子精华
新手入门, 积分 3, 距离下一级还需 17 积分
在线时间6 小时
需求：用较多adc通道来采集多路（至少16路）电压。现看中F373系列有21个采样通道（尽可能全部利用），所以想利用SDADC1、SDADC2、SDADC3的尽可能多的通道+DMA来实现。目前尝试着利用DMA2的channel3、4、5分别来存储SDADC1（3P、8P）、2（0P、1P）、3(7P、8P)三路的各自两个通道采集的电压，并分别在DMA三个通道的中断函数中将采集的电压通过串口打印。问题1：在增加SDADC_InjectedSynchroSDADC1(SDADC2,ENABLE);
& && && && && && &&&SDADC_InjectedSynchroSDADC1(SDADC3,ENABLE);
& && && &&&这两句代码后，最多只能打印出SDADC1、2两路或者SDADC1、3两路的各自4个通道的电压，不能实现6个通道全部打印。因为刚接触不久，了解有限，不清楚是否能够同时利用DMA实现三路SDADC的采集，希望大家能够给我这个菜鸟一点帮助？
问题2：由于后期需要对多路SDADC采集的数据处理，考虑在中断函数中只进行标志位的设置，在main函数中根据标志位分别将采集的电压打印，但是，采集电压打印代码在在中断函数中时，SDADC1、2两路四个通道的电压能够正常输出，但将代码移至main中，通过判断标志位来输出时，只能输出SDADC1两路通道的采集电压，这又是为什么呢？
代码如下：

STM32F373:SDADC1、2、3三路多通道+DMA采集电压
主题帖子精华
新手入门, 积分 3, 距离下一级还需 17 积分
在线时间6 小时
需求：用较多adc通道来采集多路（至少16路）电压。现看中F373系列有21个采样通道（尽可能全部利用），所以想利用SDADC1、SDADC2、SDADC3的尽可能多的通道+DMA来实现。目前尝试着利用DMA2的channel3、4、5分别来存储SDADC1（3P、8P）、2（0P、1P）、3(7P、8P)三路的各自两个通道采集的电压，并分别在DMA三个通道的中断函数中将采集的电压通过串口打印。问题1：在增加SDADC_InjectedSynchroSDADC1(SDADC2,ENABLE);
& && && && && && &&&SDADC_InjectedSynchroSDADC1(SDADC3,ENABLE);
& && && &&&这两句代码后，最多只能打印出SDADC1、2两路或者SDADC1、3两路的各自4个通道的电压，不能实现6个通道全部打印。因为刚接触不久，了解有限，不清楚是否能够同时利用DMA实现三路SDADC的采集，希望大家能够给我这个菜鸟一点帮助？
问题2：由于后期需要对多路SDADC采集的数据处理，考虑在中断函数中只进行标志位的设置，在main函数中根据标志位分别将采集的电压打印，但是，采集电压打印代码在在中断函数中时，SDADC1、2两路四个通道的电压能够正常输出，但将代码移至main中，通过判断标志位来输出时，只能输出SDADC1两路通道的采集电压，这又是为什么呢？
代码如下：
