I am active on several diffrent forums with sell/buy subforums.
Some forums doesn't allow answers and some allows threads several pages long. But all needs moderators. Not easy to administer.
Maybe the best way is to copy a working swapmeet? Yes, I am looking at Ebay.
Or a multi webshop, where every seller donates a small sum to Arduino when they register their shop? Keeps autospammers away too.

Hi ChrisS,
nice to meet you!
Sorry to upset you, and maybe my post was somewhat off topic.
Im a swede, age 49. Struggeling with the english writing too.

You might want to kill the whole german area... everybody has to post in english... so you could read it easily...

Italians, Germans, French, Asian, Russian... they all have to lern english.... but you... you don't have to learn any other language....
Not so fair?
But I respect your thread and leaves it with no further posts.

I am not convinced its a good idea.
On the contrary, my opinion is to move as much as possible to the english section. My point:
Open source is sharing.
We all want to share, help and be helped, but german or italian becomes closed source to me.

Yes, english is another language to learn. So is C, VB... And all help and datasheets are in english.
The best training is trying to try to learn to read and write in english. Google translate helps too.
I dont want  to close the internationals, its good to be able to ask for help when its necessary, arranging local meetings and so on.

But if there is going to be changes, why not make these parts as visible only for those who wants to join? Then its not in my top25 new hits to read, and the members can talk about anything the want?

Ok.
But still:
I tested http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?action=recent;display=25 and 6 out of 25 posts was nonEnglish at the moment.
And is is likely you create code on an Arduino and cant read English?

Maybe it was just one of my odd dreams. I will happily continue on this forum.

Its a nice thing to be able to talk with friends in my area.
However, speaking native languages in open source doesnt turn me on...
I would like to read and write in some threads, but I cant write in german or italian.
Is it possible to hope for everything in english?

Yes, you can use XP:s builtin unzipper, without any problems.
To me it sounds like a full harddisk?

And the serious use; my phone can be my key. Hard to copy if the code resides embedded in some kind of noise. Access to the file mght be needed. Doable?

instead of knockings, it would be fun with a recorded noise in mp3 format to unlock. or music, bad taste wouldnt get in... nofx:open, elvis:closed.

I havent checked the formula for Arduino PID, but I usally start with safe params to avoid oscillation:
P = 0.8, I = 40s, no D.
In my opinion, 0.6 < P > 1.4. Finetuning with I.
And one more thing: always avoid the PID max speed to be faster than the actuator!

I have started to create Libs as soon I have a repeating code. Saves a lot of memory.
Example:
One function I choose to name BPL.
First BPL used 4300 bytes, next 4300 bytes again. With the BPL in a Lib, first BPL uses 4300 bytes, next only 900 bytes.

Im usally trying to group functions and structs to give the user some overview.
I rather adopt an existing structure, if there is one (or two).
12  Forum 2005-2010 (read only) / Syntax & Programs / Re: Nice library structures on: February 17, 2010, 03:32:02 am
I use structs in my own library functions and notices the lack of overview in the .h file.
Somebody with a tip?

Creating librarys and other supportfiles isnt very hard.
But doing it in a readabe manner is harder.
How does it look correct and nice?
Is there coding standard for the Arduino?
14  Forum 2005-2010 (read only) / Interfacing / Re: MODBUS on Arduino on: January 25, 2010, 05:15:23 pm
I have also tried this Modbus implementation.
http://sites.google.com/site/jpmzometa/arduino-mbrt
And all credits to jpmzometa! Very easy to use, lightweight and works!
Now I can use a standard industrialgrade HMI as the frontend to the Arduino, reading logging and writing values. 30 ints/telegram with a rate of 10 telegrams/sek at 9k6. Nice.
Why isn't there standard library for Modbus?
