46  Using Arduino / Programming Questions / Re: Help on reading serial data on: October 03, 2012, 05:03:17 pm
@PGTBOOS
I'm not storing images on the Arduino. The CMUcam tracks pre-determined colors and sends back information such as the X and Y values of the middle of the mass.

The camera sends a stream of bits, does it have a wait and confirmin  signal per scan line ?.
So you go by camera scan line and then say do i have a red dot here ??.. i doubt that a bit.. it would be nice for you if it would but most likely it wont.
If you would like to detect the middle of a mass thats object recognition, and well most of such implementations require you to keep the whole image in memory which is to huge for the arduino.
I did object recognition in the past and soon in the near future again, but more often this requires a bit more memory.

In the case if you only like to detect if a certain object is red/green/bleu you can do so with 3 leds (in those colors) and a single LDR then swithc them on one after eachother and read out the LDR

Just curious how do you want to store a RGB like image of a cam on a arduino, or what would you like to do with the received data.
Because I mean even a small cam lets say (800 x 600 pixels x 3 colors) requires 1.44 Mb thats more then a arduino has.


(  i'm curious since i had been thinking of using cams with arduino to, and then abandoned the idea in favor of a cheap ITX motherboard )

Update
Well i'm no expert on this, but i decided to buy a ITX low budget board (afterall i only want to play music wth it).

Asrock E350M1, AMD A50M Fusion, CPU onboard, 2x DDR3, 4x SATA-600  (with HDMI) mostly i choose it for low power consumption.
be quiet! Pure Power L7, 300W    (silent power suply)
Corsair, 4GB, PC3-8500 (DDR3-1066)     (compatible with the mobo)
Crucial m4, 32GB, mSATA, SATA-600, SSD  (silent SSd disk, i couldnt find a smaller one, and it was not that expensive)

All together for around 150 euro, a lot cheaper then the midi hifi set i had in mind first almost 60% cheaper.
But i think its more like how i want it, a computer can play music/video and can run a website to control it.

Next i'm planning for Linux and and some media center software, i've not done much with linux any tips are welcome smiley
Meanwhile i wonder if a arduino might be used to do button input (besides DLNA imput)..
However with arduino i have no experience writing code on linux to get things done it would be cool dough.

Well i've been looking around a lot on the internet but i find it hard to find.
Does anyone know of some DIY site for creating your own audio system (TV out is not required, but its ok if the project has it).
I want a player to be able to play mp3 music
And also digital audio broadcasts (DAB)
Have a small web running so it wouldnt require a screen, but be able to be controlled from an android phone (as if it was brouwsing a web site).  > i guess some linux theatre software.
And be able to use my speakerboxes of my old (broken) audio set.  (so real speakers no PC speakers).
When i turn it on it should automatically start (so i wont need to attach a keyboard to tell it to start the music theater software).
It shouldnt need a computer power supply with fans, (they are noisy) just a small DC adapter.
It might run from SD / or USB disk
Should have an ethernet connection WIFI o UTP both it doesnt matter to my, as the router is nearby putting line to it isnt a problem.

I think its beyond Arduino, but since i am between builders here i hope someone can put my a link so i know what kind of small micro pc to use, to make it work with real boxes (old ones from pioneer)

there is more then the forum..
seen this http://arduino.cc/en/Reference/HomePage ?
i think you should try to figure it out, to learn arduino programming.
If you can get one led, more shouldnt be complex.

patterns you might do with some if(yourtest here){yourcode here} constructions.
52  Using Arduino / Programming Questions / Re: track counter on: September 23, 2012, 06:24:04 pm
there is no main void loop in your prog, you did good with setup but main a continous loop is required also.
its a loop that always goes on keeps running.

Code:
void setup() {
  // put your setup code here, to run once:

}

void loop() {
  // put your main code here, to run repeatedly:
 
}
53  Using Arduino / Interfacing w/ Software on the Computer / Re: Serial Camera Interface on: September 22, 2012, 04:08:36 pm
i am curious..
it turns out that the arduino has too little memory to store an image.
One wouldnt put a arduino in between a cam if it can be attached directly.
Are you sending the image to an extension board directly ? (wifi or ... ? )

And is the cam / arduino combination in .. well in speed match, because camera's can be fast.

Simple cheap camera's dont record in jpg they take snapshots or stream in RGB or other similar formats.
I still wouldn't choose an 8 bitter to pick apart something like a 5:5:5 RGB stream
be it rare it is decodable see http://www.fourcc.org/rgb.php ..my cheapo cam does 8bpp
56  Using Arduino / Programming Questions / Re: memory extensions ? on: September 22, 2012, 03:24:06 pm
i didnt new that netduino existed,
i was aware of another connection between visual studio and normal arduino (nice for the code completion, but some how for arduino i like its notepad editor)
I have used many editors, even when i had visual studio.
However also netduino lacks enough memory for this
Somehow thinking about it i find this strange.. USB stick prices are pretty low, memory isnt that expensive.

But maybe people are right here despite i like the arduino and its I/O possibilities, it just is to small.
Well i'm not that deeply into various micro controllers / processors any ideas for a 32 MB or more.. system that would be programmable like an arduino
(so one that includes a bootloader  usb connect or wireless etc)
As far as i know a rasberry pi has 256MB, but maybe there are others too,
I wished arduino had it but oh well something else might be better suited for it
I would like a board with lots of IO ports on it including analog/digital pins (not a strong point of the rasberry).
And preferably an active community around it like here.

just a reply to all of them above.

Well a micro controller or anothers.. it doesnt matter as long they can read c++ it shouldnt matter, the Arduino isnt worse, its a pretty cool chip in my opinion.
Pictures might for some people be complex datastructures, but realy to me it not that complex, the math i put against it is more complex then reading an image, but still my code would be small.
A small BMP picture 640x 480 is about 1 Mb
A small bmp picture 800x600 is around 1.3 Mb
So maybe 32Mb is luxery (although it would allow for image storage, in for example a motion detector application)

The tiger person sugest SRAM module,  do you have some more info on that ?.
59  Using Arduino / Programming Questions / Re: memory extensions ? on: September 22, 2012, 07:17:12 am
No i dont put my c# code inside Arduino smiley)
But C# is easy to translate (although be it a bit more work..); i first do c# for faster development, later it might become c++
I understand its a lot for arduino perspective, but compared to my labtop its almost nothing (12Gig mem)
And wel 32MB isnt realy huge, for exampl a memory stick on my desk is 4GB and the other stick is 64GB...
But i can imagine that wouldnt be addressable with arduino so much, just 32B or so would allready be fine.
60  Using Arduino / Programming Questions / memory extensions ? on: September 22, 2012, 06:36:29 am
I am in the middle of writing a c# library for image recognition.
I know the arduino has to little memory to load an image from for example a small webcam 800x600 pixels.
So i wondered are there memory extensions for arduino, ... because with a little bit more ram, say 32Mb or 64Mb or so a whole new range of applications would becomme insight.
