1K of RAM is completely out of the question, I'm afraid. The only remotely
similar thing that you _might_ be able to run on such a system is a Forth
variant. I do plan Lua on AVRs at some point, but I'll target high end AVRs
with external memory, or the new XMega.
14k of Flash also isn't good. Take a look at my project at:

http://elua.berlios.de

Currently, the bare minimum that I'd recommend for Lua on embedded would be
128k Flash/32k RAM. I can (and I will) do better than that eventually, but =
I
really don't think there's a way to go so low with requirements.

Best,
Bogdan

How small can the lua code get, and how much space does a lua_State take?<br>
<br>
With the parser and libraries stripped out, whats the smallest anybody<br>

<br>
I guess I&#39;m wondering if its absolutely out of the question, or if I&#39;d<br>
