Hi Everyone, Today Gumstix releases two camera expansion boards based on the Aptina MT9V032 CMOS sensor - actually one camera with two lenses to choose from. The current driver is for the 2.6.34 kernel. A 2.6.36 driver using the V4L2 subdevice framework is under development. We're already planning for upcoming versions so if anyone has feedback on the current design or suggestions for future models we would like to hear them. product pages: http://www.gumstix.com/store/catalog/product_info.php?products_id=254 http://www.gumstix.com/store/catalog/product_info.php?products_id=260 wiki: http://wiki.gumstix.org/index.php?title=Caspa_camera_boards -- Neil |

I expect this to be done in the next two or three weeks. I'll keep you posted on my progress here. If you're really brave you could try applying the patch to 2.6.36. This will take some tinkering though. -- Neil |

The trouble with larger sensors for me was that the codecs provided by TI won't accept anything larger than D1. This seemed to mean that you couldn't use the DSP to compress and stream 720p video. -chris On Wed, Mar 2, 2011 at 2:04 AM, Alex Gibson <al...@al...> wrote: > On 2/03/2011 4:03 AM, Neil MacMunn wrote: >> Hi Everyone, >> >> Today Gumstix releases two camera expansion boards based on the Aptina >> MT9V032 CMOS sensor - actually one camera with two lenses to choose >> from.

Here is a patch to fix the queryctl callback in the mt9v032 driver to correctly return all the parameters the driver supports when iterated using the V4L2_CTRL_FLAG_NEXT_CTRL flag. I reordered the mt9v032_controls array into ascending id to keep changes to the ioctl_queryctl() minimal.

Here is a patch ready for OE if you are using bitbake to build your kernel. https://gist.github.com/860264 To use, download and save as ${OVEROTOP}/org.openembedded.dev/recipes/linux/linux-omap3-caspapx-2.6.34/mt9v032-queryctl-ordering.patch Then edit the kernel recipe org.openembedded.dev/recipes/linux/linux-omap3-caspapx_2.6.34.bb adding one line file://defconfig \ file://mt9v032-2.6.34.patch \ + file://mt9v032-queryctl-ordering.patch \ " Then rebuild your kernel.

Thanks! I will test this patch later today and push it to gumstix-oe. -- Neil On 11-03-08 05:51 AM, Scott Ellis wrote: > Here is a patch ready for OE if you are using bitbake to build your > kernel. > > https://gist.github.com/860264 > > To use, download and save as > ${OVEROTOP}/org.openembedded.dev/recipes/linux/linux-omap3-caspapx-2.6.34/mt9v032-queryctl-ordering.patch > > Then edit the kernel recipe > org.openembedded.dev/recipes/linux/linux-omap3-caspapx_2.6.34.bb > > adding one line > > file://defconfig \ > file://mt9v032-2.6.34.patch \ > + file://mt9v032-queryctl-ordering.patch \ > " > > Then rebuild your kernel. > > On Tue, 2011-03-08 at 04:33 -0800, jumpnowdev wrote: >> Here is a patch to fix the queryctl callback in the mt9v032 driver to >> correctly return all the parameters the driver supports when iterated using >> the V4L2_CTRL_FLAG_NEXT_CTRL flag.

Looks like a wonderful product. Can you post the mass of the Caspa w/ lens + ribbon cable when you have a chance or add it to the product description?

I second this motion the overall mass is a critical piece of information that seems to be missing for the cameras. So far I have found out the weight of the Caspa VL lens(V-4303.6-1) is 5g http://www.mars-cam.com/optical/lenses/ccd_cmos/43fix.php and thats it. This kind of information is important for anyone looking to use these cameras where mass is critical, such as in UAV projects or the like.

Hello, I ran across the following article (via http://gumstix.org/community/useful-articles.html) that states "The Gumstix Overo COM on our pxOvero baseboard with the CaspaPx camera module (a Gumstix Inc. design based on the initial PIXHAWK camera) weights only 28g!" http://pixhawk.ethz.ch/2010/11/11/gumstix-overo-camera/ The Overo COM weights 4.3g. I think the pxOvero board weights 12g (according to this document: http://pixhawk.ethz.ch/wiki/_media/master_thesis_pixhawk_christian_dobler-compressed.pdf "page 81" (See http://pixhawk.ethz.ch/wiki/electronics/base_small)). So that would make the cable + Caspa module weight about 28-12-4.3= 11.7 grams. I hope it's helpful, as I'm not interested in the weights myself :). -------------- Chris.C wrote: > > I second this motion the overall mass is a critical piece of information > that seems to be missing for the cameras. > > So far I have found out the weight of the Caspa VL lens(V-4303.6-1) is 5g > http://www.mars-cam.com/optical/lenses/ccd_cmos/43fix.php and thats it. > This kind of information is important for anyone looking to use these > cameras where mass is critical, such as in UAV projects or the like. > > Thanks > Chris > > > bytor wrote: >> >> Looks like a wonderful product.

My Caspa FS weighs 18 grams, without the cable.

How about a bigger sensor area, for example 3.4 x 3.4 mm? I'm could not find 180 degree fish-eye lens with image size diameter less than 3.4mm.
