STM32F3 DMA and concurrent memory access

Hello, I'm new in STM32 World. I have a question:

I enable ADCs in my STM32F3 with dma access and microcontroller works very well, but, in F3 is not possible double buffering or pinpong method with dma, correct?

So, what is a right way to access dma stored data in main loop? I must wait DMA - Transmission Complete Interrupt before to read data?

Thank you

Well you can ping-pong between two halves of the same buffer using the HT (Half Transfer) and TC (Transfer Complete) interrupts/signals
