Hello,

I am wondering what's the utility of using the DMA when getting informations from ADC IP. Thank you.

Best regards

Well it saves the processor from being saturated by interrupts in high conversion count/rate applications.

Also, the CPU can be fully available to service other system responsibilities while the ADC is repeatedly sampling some signal, for example.
