Do you know the project MyOpenLab?
MyOpenLab uses dll to k8055 of Velleman.
The author has also integrated Arduino (and Arduclema) libraries using serial communication.
It may be interesting to create a dll to be used by MyOpenLab. You can also comment on the forums of the project MyOpenLab.
We also want to program graphically Arduino (and Arduclemas;)) from MyOpenLab through Java.
Greetings.

cOLe.

Pretty interesting. I think I'll have alook into creating a dll this weekend.

This looks pretty interesting. I can help you with the dll. But do you really want to make it act exactly like the k8055 board ? I mean is the point to create a drop in replacement ?

cool, thanks for that. I'll give it a shot over the weekend. I'll give you feedback.

Thanks again  

does this only work on the arduino with a atmega168 ? or will it work on my older atmega8 board ?

Also have you considered putting a AVR on the shield so the code required to interface with it is reduced?
Put all the low level code on the on board processor and expose a simple API over I2C or something.

I agree that would be pretty cool and not only for arduino but avr/microcontrollers in general. Just make sure that we can still program the onboard avr as well .... Darn, now I wish I thought of such a shield with the onboard avr idea. Let me know if you need help with the firmware for your onboard avr. if your planning on doing it ...  

very cool, and how much space would the library take on the chip? Will it work on a atmega8 as well ?

is there a singe sided arduino board with the max232 available anywhere? I'd like to try and etch one but I'd like it to work with the max232 chip

Very nice, if I had some surface mount chips then I would actually try and make this.

with a bit of practice you can make some pretty decent boards. These are some I made yesterday:

Have you looked at the boarduino? It doesn't have any on-board serial or USB, just headers that you can use if you want or need to. Of course, it has male pins instead of female, so that might require some re-arranging.

The boarduino is listed under the hardware page, I think.  It's pretty cheap as a kit and easy to assemble.

I had a look at it and it would work great for what I want to do, but ordering stuff from South Africa over the internet is usually either expensive or a mission. I'd like to make the boards myself.

I did some changes on S3v3rino board, and got this:


I need to make more adjusts, but I think it's the smaller board size without serial components (looking it better, I can make it a bit smaller), but Arduino fully compatible.

The sizes:
66x84mm original SSS (version2)
66x90mm S3v3rino
57x76mm TTL version

Wow, looks great. I'd love to get the eagle files for that once your done. I'll send you some boards when I make them.

Hi Everybody,

I just want to find out if anybody has made a eagle layout of a board without any ttl conversion on it. ie, no serial or usb. I've got a few projects that I want to make, but they don't need any communication access, atleast nothing permanent. I've been looking on the net for boards and I even tried modifying the original ss board schematics, but after changing the schematic I need to repopulate the board and then I can't seem to get it singe sided. I'd like to make the boards myself and I would like to have layout in eagle. Is there such a package available or shall I try again with eagle ?

Regards,
Tom

What are your other requirements, eg do you have a size requirement? Does it need to be compatible with standard shields? Pin order need to be the same?

The simplest way to go would be to etch one of the serial single sided boards that are floating around, and just not use the communications bits. Just install the power section, the microcontroller, the reset stuff etc.

Alternatively, if you have something else in mind, eg trying to get it very small, or have specific pins available (e.g. servo connectors or something) I might be interested in mucking around in Eagle to help out.

I don't really have any specific size requirement, but it would be nice to be able to have a board without the serial stuff (apart from two pins coming from the rx and tx).  Also, the pin order doesn't need to be the same and it also doesn't have to be shield compatible. I develop with my arduino but once the project is ready I just want to load it onto one of the smaller boards and then install it in an enclosure.

Mike: Sounds like a good idea. If that works then it should be fine. Thanks

Thanks for all the help everybody, I'll have a look at it.

Cool, can't wait - I've got a graphical lcd and I want to try and get it working.  

We've done something similiar at work. We've got an atmega8 with a xbee connected to the uart. The atmega8 is loaded with a bootloader (similiar to arduino bootloader) and we could program it from the a remote station (ie. pc connected to xbee module).

So, you should be able to connect a xbee to the rx/tx pins (with required level conversion circuit) of your arduino and program it from another one.
