UART v2

[davejupp]

I've noticed there's some pretty cool uart v2 displays available (well, at least one anyhow) which would be nice to use because it looks like you can cast your phone screen to it and thus navigate etc.

Does anyone familiar with this kind of embedded systems coding know of any limitations that would prevent me just adding the updated/changed message structures for uart2 in addition to the current ones, or are there hardware limitations I am not aware of, or any gotchas that anyone might know of?

The coding itself doesn't seem particularly complicated with the exception that I'm entirely unfamiliar with any restrictions/hardware demands/tricks/tips etc with dealing with an embedded platform.
