STM32F030 problem reading two ADC channels with DMA

[Mohamed eleuche]

Hello, I am getting really frustrated with this issue for almost a week.

I am trying to read PA1 and PA4 in DMA but I get only the reading of one channel and not the other one! I tried everything and I also looked at all the example online. Please help.

Why do you think that is the case? What readings do you get and what do you expect instead? Be specific.

This should be an array of uint16_t, not uint32_t.
