Add FMC via stm32-fmc crate #70

Closed richardeoin closed 3 years ago

Uses stm32-fmc

Only SDRAM supported so far
stm32-fmc only supports some of the f7 family, but I think it could be extended to cover the rest quite easily

I would too be interested in this PR … trying to implement the display of the STM32723EDISCOVERY, which is attached via the FMC.

@ctron Please go-ahead and try it out if you can. Good reports of it working will help the maintainers merge it. If you get stuck come ask in the stm32-rs channel.

However, I think stm32-fmc crate will need some work before you can use it with the STM32F723EDISCOVERY. stm32-fmc only supports SDRAM so far, whilst that board has a Display and PSRAM.

@mvertescher is there anything preventing us from merging this into master? It worked on the STM32F746G Discovery Board when I tested it about a month ago.

Nope, looks good. Glad to hear it works on one of the discovery boards. Thanks for this feature!
