Code: Select allfx=function() print("Mem free: "..tostring(node.heap()) ) end
s=string.dump(fx)
print(#s)

204 byte

Code: Select allM.setapi=function (tab,callb) M.apifunc=callb end

144 byte
Not bad, but you should count bytes!
Forth? Who can port Forth to this chip ?..

Code: Select allNodeMCU 0.9.5 build 20150118  powered by Lua 5.1.4

lhttpd.lua:1: unexpected symbol near '?'

Any ideas?

In luatool (from the same developer as Esplorer) I had to delete the very 1st character (I believe it's just a blank) in the lhttpd.lua file, then it uploads OK. Maybe it's the same for Esplorer.

Let us know how it goes.
