I'm just curious, has anyone successfully used a micro video camera (such as a pinhole camera) with the Gumstix/robostix? My idea is to use a camera similar to a CMUcam (www.cmucam.org) and stream live video accross my LAN to a separate laptop. The purpose to this is to eleminate the need of a separate video transmitter and receiver and effectively turn the system into an IP webcam of sorts. Any ideas or thoughts would be greatly appreciated.

I'm interested in doing analog video -> gumstix -> webcam. But, I'm interested to hear if anyone has attempted this yet. Thanks!

You just need to choose one that has Linux support. The most common ones seem to use the GSPCA driver (http://mxhaard.free.fr/) or the Linux UVC driver (http://linux-uvc.berlios.de/). The GSPCA driver page also has a small server and viewing utility that will allow you to stream the captured video over Ethernet. The rough outline to get a USB webcam working is... 1. Enable Video 4 Linux support in the kernel (check out target/device/gumstix/verdex for the kernel config) 2. add the driver for your web cam to the build root. 3. add any viewing software utilities to the buildroot The CMUcam interfaces via serial so you could make that work with the gumstix but the CMUcam is a completely integrated system with it's own arm processor and mmc card reader built-in. It's meant to capture and process video in a self contained package and control a robot directly. If what you want to do is stream video you are paying for a lot of extra bits with the CMU cam that you don't need. Also since the main interface to it is serial the video quality in terms of resolution and frame rate would probably be pretty low if you can do anything besides capture single still images at all. You mentioned pinhole cameras and the problem with most of those is that they have composite video output (aka, that yellow RCA jack on your old TV). This would be great if you wanted to plug into a tv or vcr but in order to interface something like that with the Gumstix you would need additional electronics to digitize the composite signal. The Gumstix does have a CCD camera interface on the 128pin connector that you could probably interface with a camera module (http://www.electronics123.com) but to do that you would need to design a custom daughter board and you would likely need to write your own driver etc... -Pete -- View this message in context: http://www.nabble.com/Video-via-Gumstix--tp16162400p16169463.html Sent from the Gumstix mailing list archive at Nabble.com. |
