106  Community / Gigs and Collaborations / Re: UART(COM port) baud rate converter? Help anyone? on: September 02, 2012, 07:44:54 am
OK .... so ...

We have two frequencies going on here, and some confusion as to the requirements of the "baud" rate.

The interface speed of the GPS is the baud rate, the rate at which it sends messages is the message rate, the two are not really inter dependent unless you are expecting to be transmitting data at 32 baud smiley

So even if the messages are coming in at 10Hz unless there is a VERY good reason why not then they can also go out at 10 Hz independently of the baud rates.

The very simple serial repeater posted by Rob will do what you want, all you have to do is extend it to have the number of ports you are expecting to repeat to and specify the pins you are intending to use for the soft serial library. Most NMEA sentences are quite short and will not require buffering but can just be squirted directly out.

If you need more guidance with the coding just shout, I am sure there are plenty of people including myself who can knock this up in 5 minutes for you.

If my understanding is too simplistic and you do need to be throttling the NEMA message rate then it all gets much more complicated.

Cheers Pete.

You just read from one port and write to another, probably 20 lines of code

Code:
setup () {
   Serial1.begin (115200);
   Serial2.begin (9600);
}

loop () {
   if (Serial1.available())
       Serial2.write(Serial1.read());
}

Make that 8 lines smiley

Rob



You may want to add the lines that define the pins used in the softserial library too smiley

@ Peter Baines for your INformation , I was able to work all the stuff out myself and have no problem now, What I was trying to depict is the possible hardships that may occur while you implement the stuff!

Excellent news .................

Nothing quite a satisfying as figuring it out for yourself is there ?

Now that you have all the answers i guess the cost of development now comes down  smiley-wink

Cheers Pete.

Hi .....

I am not really understanding what you need the money for.

If you are doing it, software development costs nothing . Most people who develop commercial software here on the forum develop it first and demonstrate its merit and then try and sell the finished product. I can frequently be found here selling my services but i would not ask a client to invest in my services without some proof that I could deliver also.

Try telling us why you need the money and exactly what you are trying to develop.

There are a lot of CNC control programs out there in the freeware world already.
What would we get for or 20 then we cannot get for free.

Best of luck with this.

Cheers Pete.

Surely a single gyro will do the job central to the 4 legs.

The leveling algorithm/movement would be the same as a quad copter.

In fact this is just a quad copter project with a bit of a twist in the propulsion systems ..... or am i missing something here smiley-lol

I guess the problem you have here is production costs. The per unit cost can only come down f you are going to be ordering very large volumes of these devices.

How many do you think yo may be requiring per batch order.

The design is not problematic, the hardware is out there if yo are prepared to make compromises on functionality over cost.

I have sent you a PM with my details in it.

I take on start up projects from time to time and an old good friend of mine was working on the water issues in Africa before he died a few years ago and so I am willing to donate my time to help.

Cheers Pete.
113  Community / Local Groups / Anyone in 46500 France looking to set up a local group. on: August 18, 2012, 02:49:11 pm
Hello Folks,

I am a Welshman living in France and working with Arduino and ATmel CPUs. I am looking to try and get a user group together for winter meetings and collaborative projects. I run a small B&B in the summer and so my time it limited but after September i have lots of time to dedicate. I speak some french but would not call myself fluent. Perhaps this group could serve as a language exchange also but with a theme of Arduino development.

If you are interested then please drop me a PM.

I have also been thinking about running residential programming/hardware design workshops from my B&Bin the winter over a weekend.
If anyone thinks they would like to help to organize these than also lease drop me a PM

Cheers Pete.

@ NI$HANT, Sorry but I have just gone through all the post by you in this thread and I can't seem to find the bit where you talk about carriers (apart from your reply to me), you do talk about bands, perhaps we have a misunderstanding of terms here.

You are right that SMS is an easy option but then not everywhere has GPRS and so in order to have a system that falls back to the lowest common denominator SMS over GSM is the obvious choice.

Why over complicate a system ?

"KISS" is the name of the game in cost effective development where future extensibility is not a show stopper.

I have no desire to get into a debate over this, i was just stating that I have not experienced the difficulties that you cite when explaining the complexities and subsequent cost of mobile communications development using either GPRS or GSM .

Perhaps i can help you to solve some of the issues you are having.


Cheers Pete.

Interestingly I am not having such headaches with the system I am designing for a client that control access to vehicles over the GSM network using SMS based calls and commands. The same board also has accelerometers and an extended SPI interface to chatter with other modules in the collection. My client is using a simple GSM shield that I have placed onto a custom PCB along with a ATMerga328 and supporting bits and bobs ( i cannot be too specific as it would violate my NDA )

Cheers Pete.

I'm not aware of how to send an SMS from a regular land line, but that'd be worth looking into.

Hi Jack, I already contacted the OP before and had a very detailed talk on the quote I made to him , but he was looking for something way cheaper , The thing here everybody needs to understand who has not experienced sending sms or calls using the telephony system is that the cost of hardware is costly and is complex in making the system dependable , i have worked a lot with independent telephony cellular modules like SIM 300 etc and SMB5100 etc among other and have noted that the programming to have dependable real time systems with these is really tricky and involves considerable headache and hardwork so this project is going to be somewhat costly.

Hello Nuno,

Is this the Camera lens controller system I have designed and built for you that you could not get to work with the lens because the lens serial port was not working. Perhaps it might be a good idea if anyone else takes this on to have a chat with me about the existing issues that remain unresolved.

Don’t forget that the system I built for you is based on a Netduino and not an Arduino although crossing over is not difficult.

Cheers Pete.

117  Community / Gigs and Collaborations / Re: I Need a arduino or robot In Exchange I Will make you a website of your choice! on: April 15, 2012, 03:05:02 pm
100Grand ->

If this is the case then I can do that myself.

I was expecting to be getting a Website to which I will own ALL the code and IP not something "painted by numbers".

This means that I will not be proceeding with this deal any longer thank you.


Cheers Pete.


dropdeaddick ->

Thanks for he heads-up....



I wasn't trying to step on your toes, I just happen to recognize that template as I have used it myself and felt that it is only fair that you divulge that you are not doing one off work. Good luck with your project.




118  Community / Gigs and Collaborations / Re: I Need a arduino or robot In Exchange I Will make you a website of your choice! on: April 13, 2012, 01:00:10 pm
When i say "Host" it that is what i meant not somewhere to store it. I need to be able to open it up in my browsers Internet Explorer, Firefox, Chrome etc and use it like it was going live in order to test it. I have several VPN that i can proxy through to test the language selection is working smiley

If you download the existing page BOTH the english and the french sections are there. They are just in hidden DIVs so you dont need to do any translation at all. Alternativly i can get you the source of the exisiting webpages if you want. Send me a PM for my personal email and i will zip it up and send it to you.

For your troubles i will send you an Arduino Mega and depending on the qaulity of your work perhaps an LCD shield and the LCD screen also.

I look forward to seeing your work.


Pete.

Yes i have a place to host it, I will upload it onto a FTP host.  And You will keep all existing content. And I for the english selection I will Translate everything from french to english...

Thanks!!

What Am I getting in return? you can send whatever after Im done finishing the website



OK do you have somewhere to host this so I can see it before loading onto my servers and to give feedback as it progresses ?

I guess you are going to be taking ALL of my existing content and building it all into the new layout INCLUDING the route calculator and the google maps etc.



2. ASP.Net error was a script overload of the IP range a ip in your part in the world wouldn't probably get this message.

3. I Am still working on my website and the xBrowserX compatibility was because I have not worked on that website for 1-2 years because I stopped paying for my minecraft server

STOP !!

I have not asked you to start but have been trying to establish your ability to answer my questions and reservations based on your answers to my questions.

I understand that you are keen and willing to do the job but I am not ready to commit until I am happy that you are able to resolve the issues I have.

Cheers Pete.

So would you like me to start right away??  smiley  because it would be done in about 1 week but!!! you have to tell me... Do you want me to upload the files or do you want me to give you the files??
