Porting eLua to the NetDuino

Hi,

I've been looking into porting eLua to the Netduino.
Currently eLua supports the Netduino chip (at91sam7x512) but not the board i.e. I can build and flash the firmware but the device does not seem to boot.
Diagnosing this without JTAG is going to be ... very interesting.

I was wondering if anyone here with low level board support skills would be willing to have a look into the port and report back any findings / insight?

Lua is a wonderfully easy language to teach to kids and I'd like to expand the reach and capabilities of the Netduino through this.
(after a sucessful Lua port, I'd probably look into PyMite next).

I look forward to your responses.

EDIT:

Turns out that eLua DOES boot. I just had the incorrect serial port connected (UART2 i.e. pins D2&D3 are required, not D0 and D1).
This means that the default compile works for the Netduino, exciting stuff! I will post progress in this thread.

How is yu progress going..i was thinking of converting Lua to c# so i could use both enviroment. Want to create an appin c# but allow users to create scripts in Lua if required.

Hi

 

Perhaps you can help I am stuck getting elua running on a netduino.

 

I believe I have it flashed. But I am having touble taking to the board. I am using a terminal to talk to the netduino using a USB BUB II. When I plug the netduinoI see a message with a elua prompt (very exciting!) but for every thing I type on the console I get a resonce of a 0xffff character.

 

Thanks apprecitate any help.

It seems like what you are doing is a step backward. You are giving up all of the very attractive features
of a Netduino and the Micro Framework such as two high level comprehensive development languages with easy
debugging features. If you want to use eLua, why not just use the ET-STM32 stamp from Futurlec,

I loaded the prebuilt binary from http://www.eluaproje...arted/downloads and it works quite well on this board.

baxter,

 

which binary did you use for the eLua download into Netduino?  Or did they remove it?  I see one for an Atmel based Netduino, but none for the STMicro STM32F4?

I only tried the binary for the ET-STM32 Stamp.
