I actually have an LM3S9B92 around as well, and I thought I had added support for CAN on this platform, but I don't currently see it in SVN. I'll look around this evening to see if I either have the code lurking somewhere that didn't get merged, or I will add an implementation. I don't think it should take me more than a half an hour to implement it if I still have enough transceivers around to do some testing. The CAN module only has 3 functions and most of the heavy lifting is done in hardware :-)

I doubt it. How do I do that? Sorry - this is probably really basic, but I have googled with no luck.
I'm afraid CAN is not yet available for LM3Ss :( as James (who has implemented CAN) only has an LM3S6965.
It works well on STM32 though.
And yes, we expect to extend it to other platforms too. (as long as we can get our hands to some kits ....)

Hi - can someone tell me what I'm missing? I've spent a few hours poking
around in the source (mostly platform) and cant do a require('can'). I'm
using:
scons board=ek-lm3s8962 toolchain=codesourcery prog
All builds and downloads fine. Added an X after PUC-Rio to test for idiot
factor. This is what I get:
eLua trunk pos0.7 Copyright (C) 2007-2010 www.eluaproject.org
eLua# lua
Press CTRL+Z to exit Lua
Lua 5.1.4 Copyright (C) 1994-2008 Lua.org, PUC-Rio X
> require ('can')
stdin:1: module 'can' not found:
no field package.preload['can']

no file '/rom/can.lc'
no file './can.so'
no file '/usr/local/lib/lua/5.1/can.so'
no file '/usr/local/lib/lua/5.1/loadall.so'
stack traceback:

[C]: ?
Similar result with eLua 0.7 release.
Thanks, Owen

Currently eLua doesn't have binary modules support, and since CAN is a
binary (C code) module you need to enable it at build time, then you
can use it directly (without 'require'). Is CAN support enabled in
your build?
Best,
Bogdan
