I'm using the STM32F446VE with 3 ADCs. I have a 50 kHz PWM running and want 2 of the ADCs to measure 2 Channels synchronized with the 50 kHz PWM.To achive this I used the regular simultanuous dual mode, and triggered the master ADC with the Trigger 8...

I'm measuring 2 channels per ADC, this is why I am using the DMA. But I want channel 1 of ADC 1 to be synchronized with the channel 1 of ADC 2, same with the channel 2.

Thanks for your reply! This explains why making the ADC conversion slower does not generate an overrun.Why would a FIFO help here? I always thought without FIFO the DMA just overwrites the old values, which is the behaviour I want. I don't care about...
