I'm not sure of how to do this, but I need to store a large amount of data on my mcu(around 4 times larger than the SRAM the mcu has), for a brief period of time. I'll be using the nucleo-F722ZE ( STM32F722ZE ).
It has a flexible memory controller, so in theory I think I can map SRAM to the board through the FMC and use the DMA to quickly store the data as it comes in. I just want to double check if this is possible and how much slower would it be than accessing internal SRAM.
I'm thinking of using the following SRAM:
Any help would really be appreciated as this is not something I'm at all familiar with.
Thanks in advance.
