As promised in my last post, here is a quick demo of the eCAM32 3.2 megapixel camera connected to the Gumstix Overo Water. I am presenting two videos, one showing the setup where the eCAM32 camera board is mounted on top of the Gumstix Overo Water, the other one being a screen cast demonstrating some of the most common settings of the camera. I am using the Tobi expansion board because it has Ethernet interface allowing me to stream H.264 encoded video to a host PC running linux.
DSP
The e-CAM32 and e-CAM50 cameras
As I mentioned in my previous post, I had only had limited success with the Caspa VL and Logitech UVC cameras. While both cameras work with the Gumstix, the Caspa seems to take poor images while the Logitech USB camera performance is limited by low USB bandwidth. Therefore, I have decided to try my luck with cameras from e-Con Systems.
Video encoding using the DSP is working
I’m happy to report that I am now able to encode video on the Gumstix Overo Water using the DSP in the OMAP3530. It wasn’t difficult to make it work but it took several attempts at building the kernel before I got it right and, as you might know, cross compilation takes time.
Work continues on the OMAP3 VPU
A year has passed since we had a Gumstix Overo based video recorder onboard an amateur rocket and it is time to resume working on it. This time I will continue towards the original goal, namely live radio transmission of video encoded using the built-in DSP.
AO-27 orbit 93036 received with Gqrx and Funcube Dongle
FM traffic and packet radio from the AO-27 amateur radio satellite. I made this recording last Saturday while testing the Gqrx software receiver using the cross yagis at OZ7SAT and the Funcube Dongle.
USRP E100 Now on Sale!
I woke up at 4 AM last night and couldn’t fall into sleep right away, so I got up and started reading emails. To my great surprise there was an email from Matt Ettus announcing the availability of the USRP E100 in mid December. The E100 here is according to the new naming convention used by Ettus: E=embedded, 1=first generation, 00=revision number – or something like that. So it is indeed the Embedded USRP I wrote about in July, which back then was based on some info I picked up on another mailing list and a press release.
