Synchronization of two DMAs

Hello, I need generate via DAC and measure via ADC at the same time (when I connect DAC with ADC, I should exatly measure what I generate). Transmissions from ADC and to DAC are now via DMA.

Is it possible to synchronize these two DMA (=synchronize ADC with DAC)? Thank you very much for answeres

Yes, you'd use a TIM channel to trigger the ADC/DAC, both could share the same channel, or if required 2 different channels to provide a slight phase relationship to compensate for any measurable latency.

You should review the manual to see what timer/channel choices are available for each.
