......... and I might also suggest you start flashing a special built image for the EK-LM3S8962 we have prepared and made available on the site under the "Official Custom Build Binaries", the LM3S Games.

http://elua.giga.puc-rio.br/downloads/elua_games_EK-LM3S8962.bin

You will have an autorun menu show up on your OLED display, where you can select among 6~7 diferent games and demos for the LM3S board and have some fun even before typing your first command on an eLua Terminal.

Hi Dado

Yes it's the EK-LM3S8962.

Cool. So the links I've sent you are the right ones to start with.
 

I thought I would have to use Windoze.

Yeap, at least to start with I suggest you stay on Windows. The Luminary Program to flash the kit is very nice, reliable and easy to use. But yes, it only runs on Windows. I've used it many times on Virtual Machines in Ubuntu, under VMWare and VirtualBox with no problem too.

Do you think I can load the eLua image via Linux? I have lot of OSs here but I would love to use Ubuntu if possible.

James Snyder has been able to flash EK-LM3S6965 boards (basically the same FTDI type of interfacing to JTag) under Linux and I have a receipe for this. I'll test it here too and prepare a tutorial but I can't promisse anything for too soon.
 

Thanks very much, yet again-Patrick

You can start with the official eLua v0.7 binary image for your board. They are all available for download at our Downloads->Binaries page and the one you need is http://prdownload.berlios.de/elua/elua0.7_lua_lm3s8962.bin
 
Please let us know how it goes (and if you can beat Téo on Pong :)

Dado

Pattrick,
anything you need to start, just let us know.

This LM3S is the best board (at least the best that I know) to start on eLua.
This is a board we use a lot and we are more than happy to help you.

I wish you luck to beat me on Pong! :)

Maybe I will dream about pong tonight ;-) talk soon-Patrick

You definitely don't need to buy any tools. You have two choices here:

1. build your own toolchain (http://www.eluaproject.net/en_tc_cortex.html)
2. use an existing toolchain (for example CodeSourcery).

I'd go with 2 above, it's a much easier option for a beginner (although it generally leads to slightly larger images). Once you installed the lite version of the CodeSourcery toolchain (http://www.codesourcery.com/sgpp/lite/arm/portal/subscription?@template=lite, you need the EABI version), all you need to do is this:

$ scons cpu=lm3s8962 toolchain=codesourcery prog

Then enjoy :) More details about building are here : http://www.eluaproject.net/en_building.html#configuring

Best,
Bogdan

Hi Dado

I received my development board. I was a little bit disappointed with their whole g++ thing. I am hoping that I do not need to pay for some sort of IDE that is just a front to the free GCC but I don't need this do I? Can I just load one of the eLua images over to the board via Jtag and then connect to it via serial? Could you help me get started?

Hope your doing great, sorry to bug you with this-Patrick

And if you want to spend some more (~$100) on an ARM Cortex-M3 kit, there is the EK-LM3S8962 from Luminary Micro/Texas Instruments that has a nice little OLED display, for which we have a bunch of games and other demo apps too.

http://www.luminarymicro.com/products/lm3s8962_can_ethernet_evaluation_kit.html

It does not have the "stamp" form like the ET-STM32, the mbed or the MOD711 and it is a bit limited on GPIO too.
But it has header pins for easy prototyping, onboard buttons, a very simple and good free Flashing program, it is powered by the USB cable, it implements a serial COM over the same USB cable, it has a ready-to-use ethernet connector and other start facilities.

   For me, they all look equally complex (or equally simple, it
   depends on your angle :) ). I'd start with a Cortex-M3 though,
   they're somehow easier to understand IMO, and their implementation
   details don't vary that much from manufacturer to manufacturer as
   it happens with ARMs. This is one board that I use a lot, performs
   very well and has a good price:

   http://www.futurlec.com/ET-STM32_Stamp.shtml

   (and of course, it is supported by eLua)

   Best,

       Thanks again guys for all your great tips. I am looking
       through the ROM images and the eLua examples at googlecode. I
       am also reading just basic C and assembly stuff related to
       microcontrollers.

       I can see under platform info a list of device families. I was
       just wondering if there was one family that was simpler to get
       started with?

       Thanks-Patrick
