Newbie STM32F4 DMA questions.

Question asked by foxcube on Nov 21, 2011
Hi. I've been using dsPIC33 for a long time and I'm looking for something with more power. I've just started playing with an STM32F4 Discovery board. 

The application I have in mind is a high speed external DAC (16Msps) attached to the FSMC. I need to have double-buffered DMA for seamless and synchronous output, but it looks as though this is not possible, because memory to memory DMA cannot use double buffering. Is this correct, or is the FSMC classed as a peripheral rather than memory?
