It's Lua not LUA. You're probably looking at NodeMCU on ESP8266.
Have you studied the materials at ?
Compared to PC users living with a wealth of library import
options and on-line examples for python I fear the experience on
an embedded device will be less fancy for micropython but as well
as with LUA . Especially for control algorithms you will have to
start from scratch using LUA? Is there support for http:// GET ?
I think it can do plenty, but remember on-chip SRAM is limited if
you are not using a separate MCU. "Control algorithms" is pretty
vague, but hobbyists using NodeMCU for basic IoT-stuff sequencing
are doing fine. If you need the faster kind of control algorithms,
just download the SDK+compiler VM image and use gcc.
The second point is UML round trip support, having code
generation. Is there some 4 GL SE support for LUA?
Lua is a scripting language that is often embedded in software
apps, see . Note it's not "embedded as in MCUs"... It has been
adapted to run on MCUs with small memory footprints, *however*
it's still a scripting language that juggles objects and do
garbage collection. Large apps may use plenty of memory and
garbage collection is not your usual deterministic memory usage
So it's not a purpose-built embedded systems development tool with
all the UML or 4GL or whatnot tools. I believe it just happened
that there was a Lua for MCUs -- eLua -- that could be quickly
ported to ESP8266, creating NodeMCU, which turned out great for
speedy project development, perfect for the maker demographic,
which is probably the main target customer for the boards.
