Having trouble setting up DMA for both ADC1 and ADC2 on STM32F103C8T6 (Blue Pill)

[chopfensperger]

I currently have ADC1 working with DMA at 14 MHz so my sample rate is 1 Msps I believe. I want to double my sample rate, so I thought I could use both ADCs with DMA and interleave the buffer data. My issue is that when I am trying to configure ADC2, there is no "DMA Settings" tab, and when I go to adjust the DMA configuration, I am not able to add a DMA request for ADC2. Am I unable to use DMA for both ADCs on the Blue Pill, or am I missing something?

Here is what my ADC1 configuration page looks like with the available "DMA Settings" tab.

Here is what my ADC2 configuration page looks like without the available "DMA Settings" tab.

Here is what my DMA configuration page looks like without the option to add a DMA request for ADC2.

Any help is appreciated!

ADC2 doesn't have a DMA trigger, only ADC1.

Might be able to set it up in dual mode to get this data out.
