Hi & welcome !
Iam working with upp ide several years ago on desktop windows/linux enviroments.

Iam glad to inform you, I have some successfull babysteps on usage of the same .lay file in my embeded eviroment.
(so my small cltr, and several CtrlLib widget architecture use similar interace, but the any other compatibility was not a goal)
This implementation is running on xmos controllers natively (ram: n*64k), and it is actually fits one tile with the lcd and sdram codes.

Actually(+1year) Iam looking for help to design and develop something which is reusable for others, or convergates to the reusable requirements/concepts.
