Possible Camera
Good Morning Community, I was browsing around the other day and found a cmos camera at http://www.sparkfun.com/commerce/product_info.php?products_id=8668. Its a 1.3 mega pixel camera and doesn't have much current draw and under $10. I'm not an electrical engineer but was wondering how feasible(with some soldering skills and a basic electronic understanding) it would be to attach this the the freerunner? The data sheet is included on the site. Thank you all in advance for your help. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
Re: Possible Camera
I was thinking about soldering camera myself(also I will try to change 2.5 jack to 3.5). just expressing my interest in this thread.

The data sheet is included on the site. Thank you all in advance for your help. I assume you are thinking of building a small daughter board with the camera on, connecting that board to the freerunner mainboard somehow, and mounting the camera in a modded case? I would say your chances of adding one to an existing freerunner is quite slim. The freerunner has an I2C bus to control it so that part would be easy, but it looks like it needs an 8 bit I/O port to get the picture data out, and I don't think the freerunner has an accessable one you could tap into. Also the whole camera is surface mount, which would make it fairly tricky to mount on your daughter board. None of these things would prevent a camera like this being included in a future OpenMoko design, but don't think it would be possible for anyone to add a camera like this to an existing phone. If you want a working camera on your freerunner, then I suggest you look for one that connects via USB, as that is a much easer bus to connect to. -- David Pottage Error compiling committee.c To many arguments to function. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
Re: Possible Camera
I may do that as well, I also saw a 2000 mah battery that's about should fit the case as well. The camera, if I remember correctly might be able to be used one the i2c bus? Well off to work, ill do some research later.

Re: Possible Camera
just expressing my interest in this thread. Replying for the same reason. I was comparing the phone with the PCB, http://wiki.openmoko.org/wiki/Image:Menu9.jpg with http://wiki.openmoko.org/wiki/Image:Gta02a5_pcba_cs.JPG , and it seems that there is quite not a lot of space left. The site got a link to such a nice datasheet (http://www.sparkfun.com/datasheets/Sensors/Imaging/TCM8240MD.pdf); it seems not up to date though: the last page (30) states: Reference Drawing Module shape is not finalized yet in detail. Following drawings are only reference for initial study. The properties say it is a document from somewhere in 2004, so you'd say we're on the safe side then. The numbers are not so easy to read, do you also read the total height of the module is 7 mm? Anyway, it seems interesting.

The data sheet is included on the site. Thank you all in advance for your help. I took a quick look at the datasheet. You need an 8 bit parallel data port and I2C to control it. Does freerunner even have enough pins available to attempt an interface? I'm not sure what we have available in terms of expansion ports. I also seem to remember some talk in the sparkfun forums about it needing to clock the data out high enough speeds that microcontrollers have trouble keeping up. I know the Freerunner CPU is a lot faster than a normal micro, but it's also busy doing other things. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

Re: Possible Camera
i don't think it would be a problem. Simple avr processor can handle this camera. And here we have 400Mhz processor with i2c support. The question is do we have unused i2c bus to connect this camera?

Is this true? Or is it a little more complicated? Yes, you can get raw RGB output. The best forum I've found for playing with these cameras is this one: http://forum.sparkfun.com/viewtopic.php?t=10314postdays=0postorder=ascstart=0sid=01c7b713e0788e0041b2342368248ef6 You can also get JPEG output, which is why I was originally interested in it (again, not for my Neo). The main problem you'll probably have with the camera, though, is that is requires that you clock data out of it at at least 8MHz - so your processor needs to be considerably faster than that for you to be able to fetch a byte and store it somewhere before it comes time to get the next byte. - Michael ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

But what are you going to do with the RGB-data-stream??? And here we have 400Mhz processor with i2c support. The question is do we have unused i2c bus to connect this camera? I2C is a bus. You don't have to have a unused one, you can share the existing system-wide I2C bus. But we don't have *any* sufficient number of GPIO spare on the CPU that you might use, not to mention there's a camera-interface that's dual-used for other things on FR. So no way to get the actual picture data to video-ram realtime for a viewfinder etc. Suggest: use USB /j signature.asc Description: This is a digitally signed message part. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
Re: Possible Camera
These were the batteries i was looking at earlier, does the freerunner have room in the battery compartment from these, I think I may have glanced over the dimensions... With this battery listed you can get a small protection circuit for safety.
