Agreed.  Looking at the block diagram of the STM32F746xx, getting the
data into SRAM is easy, an ADC to APB clocked at 216 MHz, an APB to
AHB bridge, a DMA controller, and into 240 KB of SRAM.  Next job is to
get the data out of the SRAM through something that will take the
flow.  Might have to restrict the rate to whatever delivery method is
used, or add some local processing.

Still, the board looks like fun for a reasonable price, so I'll
remember it for a while.  ;-)
