For the next revision, may I suggest also adding the capability to offload the file. For example, have it with an ethernet port and you can have an internet enabled camera. Have the board take a shot, and offload it to the ethernet (via FTP possibly), OR depending on configuration, save it to the SD card, or maybe even both. Having a way to automatically offload the image file means you won't have to stop every so often to empty the SD card, and you can have a camera that can function forever, or till the electronics fail, whichever comes first.

Hi guys - can I power the JPEG trigger by connecting the 1-5V pin to my Arduino Uno +5V? Or should I use a separate source...

Also - I'm confused by the trigger pins, say for D2, do I need to hook up the 5V and GND or just the trigger pin?

Thanks

How can I send the text file created via serial or newsoftserail? So I can send the picture via Xbee and also have it saved.

I can't tell from the previous posts if the "smoking" problem with the lipo is resolved on the DEV-10549 board. Also, are the two rows of three holes just above "Spark" for the AVI programmer? If so, which are which?

One more thing; the source code mentions a "testing jig" and a test mode. I see no documentation on this. Is it available?

Thanks in advance for your help!

what might be happening? ... arduino v.1.02

JPEG_Sample.pde: In function 'void setup()': JPEG_Sample:41: error: 'class MemoryCardDevice' has no member named 'begin' JPEG_Sample:62: error: 'class MemoryCardDevice' has no member named 'open' JPEG_Sample:73: error: 'BYTE' was not declared in this scope

How long should it take to record a picture using the JPEG Trigger? I ask because I'm trying to decide if I want one, so I breadboarded up a prototype with an arduino, sd card & camera. While the system worked, it took about 30 seconds to record a picture. I admit that that could be due to a problem that I caused, but if that is the expected time required, it seems a bit disappointing.

Also, I had to change some headers to get the software to work with Arduino 1.0; and I found a bug where the jpeg size was overflowing (it should be stored in an unsigned int). But, thank you so much, sparkfun, for the otherwise great source code!

We have done practices with JPEG Trigger board and LinkSprite JPEG Color Camera but we have found one problem that appear be reading memory card microSD. The problem with JPEG Trigger board consist in that blink red led even if we formatted the memory card is FAT16.

We have used two memory cards: 1. MicroSD 1GB 2. SanDisk 2GB Both memory cards were FAT16 formatted as follows: 1. Windows format: FAT(predetermined) 2. Ubuntu: GParted > FAT16 format 3. SDFormatter software (on Windows): Format type > Quick, Format Size Adjustment > Off Despite testing, red led blink.

Too, we downloaded the last source code for arduino that appears in this product web site. We upload this code to JPED Trigger. We perform same tests but this does not solve the problem.

We do follow the code and found that the program ends in follows line:

//Initialize the SD Card
//If the card initialization fails, blink the LED and stop the program

if(!(MemoryCard.begin())){
    systemStatus=PROCESSING;
    Serial.println(systemStatus); //Problem!!!    
    while(1);    
 }

This means that memory memory card does not start well. Why can be this? What can we do for solve the problem?

Thanks for comments.

I've been trying to get this board to work but I haven't been able. The trigger is telling me that the microSD card is not well formatted, that the format must be FAT16, I have formatted the card using windows and the FAT option as there are only two options: FAT and FAT32, so I supposed the only FAT should be FAT16, but this is not working. Are there any special options or conditions to format the microSD card?

On the other hand I have noticed the ATMega microcontroller in the board in getting pretty warm, is this normal?, or it may be a malfunction?

Aprecciate your comments,

I just got my 2nd board delivered after the 1st one acted like a toaster. This 2nd one took 4 pics and then did the same thing. To be exact - I took 2 pics, removed the card and checked them all out. Did the same again - no problem, put the card back in and turned on - toaster time.

This is a 30 dollar dud product and should be removed until the problems are fixed. It is not ok to sell products with this kind of consistent problem.

As above, it seems the source code no longer works under Arduino 1.0. This line:

  MemoryCard.file.print(response[i], BYTE);

Throws the error "The 'BYTE' keyword is no longer supported". It says that this is an Arduino 1.0 issue and to use Serial.write() instead. As suggested elsewhere, I tried changing the line to:

  MemoryCard.file.print(response[i]);

Also, the included libraries throw a bunch of errors from the WProgram.h which, so far as I can tell, has been changed to Arduino.h. Changing all instances in the JPEGCamera and MemoryCard libraries seems to solve the issue. Finally, I'm getting this error and don't know what to do with it:

In file included from JpegTrigger.cpp:39: /Users/jthompson9/Documents/Arduino/libraries/NewSoftSerial/NewSoftSerial.h:55: error: conflicting return type specified for 'virtual void NewSoftSerial::write(uint8_t)' /Applications/Arduino.app/Contents/Resources/Java/hardware/arduino/cores/arduino/Print.h:48: error: overriding 'virtual size_t Print::write(uint8_t)'

At the moment my board is a bit useless. Looks like the code could use a little love... :)

Jpeg trigger and Jpeg camera are good. But The latest libraries won't work in arduino 1.0 . When will the code libraries updated for arduino 1.0.

Also the atmega328p on jpeg trigger gets heated while under process. I have used 5volt DC supply for jpeg trigger. Why is at-mega328p heating beyond actual working noraml temperatures?.

Also jpeg trigger make use of software serial to communicate with camera. Soft serial is little slower. Thus trigger takes time to get a picture. Again the chunk size is 32. Can I increase the chunk size to 64 or 72 or 80 to increase the speed of picture grapping process. Regards, P.R.B

Just starting to work with this board but a little gun shy to plug up the battery. Do we know if there is a fix to the shorting problem reported? Thanks.

I bought a few days ago JPEG Trigger, but while I was testing the card with the Li-po battery, the card began to become very hot and emitted a burning smell and the led never caught.
Also separately connect the FTDI and the LED starts blinking, and format the SD to FAT16 and does not change often.
Check the continuity between 1-5 V and GND and continuity between these two pins, I think this should not be.
Apparently there is a short circuit on the PCB.
As I can solve my problem?
Thanks for the support and excuse my English

How do you load an edited source code to the jpeg trigger?

is there a way so you can get a web cam and cut then usb off and solder it to this to wark insted of the 50$ camera you wants us to buy for this to work also could you add a pir motion sensor to trigger this?

Hi guys,
i have a rare problem: the size returned by:
count = camera.getSize(response, &size);
is a negative number like -202453
then, never enter to the while:
address=0;
eof=0;
size=abs(size);
while(address < size)
{
then i get a 0 bytes .jpg files on my SD
* i have the last code
* the SD init its OK
* the comunication with the SD its OK ( i tried write other files)
* the comunication with the camera its OK (at least, the reset command return rigth bytes)
this is one size response for example (the first 7 bytes its ok acording to camera datashet!):
76
0
34
0
4
0
0
FFFFFFBF
6C
any idea?

What is the maximum size of the microSD card that I can use?
I have a 2 GB card (formated with vista FAT(Default))
Once I put in the microSD the Led goes out and never lights up again, also the board appears to get hot so I unplugged it after 2 minutes. I use the lipo battery PRT-00341 to power the board.
Nothing is wired to the triggers and the camera is not plugged-in.
I also had some kind of short problem with my first board that SFE replaced ( kudos for customer service :) )

I bought the jpeg trigger and the camera, I wired them and I powered the jpeg trigger with 5vdc (as is written on the board) at the terminals next to the battery block. When I powered it on the led lighted up and everything seemed ok (we didnt trigger it to take a picture)and the power consumption was 0. Then we powered it off and when we powered it again on we saw that the power consumption was up to 2,5A. What do you think happened?? Is something wrong?? Can we do something to fix it??

I plugged my 3.7v (1000mA) lipo in, and the thing started to stink like something was shorted. The LED never lit, and I'm really sad about this now. :(
How do I return it?

I ordered one of these a couple of weeks ago, and am finally getting a chance to take play around with it...
I'd like to see the source, and that format isn't familiar to me. So, at the risk of sounding like a moron, what format is a .PDE file?

Barring scanning the source code, what happens if you take more than 1000 pictures?

It looks as though the ATMega328 can be reprogrammed through an ISP connector. Is there a loadable image file available for the as-shipped firmware?
It would be very comforting to be able to reload the as-shipped firmware after mucking about with custom code.

This product description indicates that it is powered at 3.3V. However, the product description for the LinkSprite JPEG camera says that it only works reliably at 5V, not at 3.3V. Do these then need to be powered separately?

What are the chances of this working with the eye fi cards? http://www.eye.fi/

why so many different choices for which pin to ground? are they all slightly different, or just to make it easier for more things to cause an exposure?
