STM32 double buffer + ADC + FATFS necessary?

Hey everyone,

In my last application I had a DMA double buffer moving data from a peripheral to memory, it would fll one buffer, inform the cpu and while it filled the second buffer, the first buffer would be sent to the sdcard.

I want to do the same thing but using the stm32's internal ADC's although I'm not sure whether it would be necessary? If you have circular buffers how are they usually processed during continous conversions without using double buffer mode?

Thanks in advance for any help!
