I'm not expert in kernel programming, but | I'd like to contribute to the development of m5602, if I'm able to do | something useful. | | Here is my situation: I use an Acer Aspire 5610Z, which includes an Ali | webcam based on m5602. Today I managed for the first time to view | something on livecam, using m5602-s5k83a. | What are your results using the m5602 branch? | I can use all livecam modes, but the RGB24 ones. I can't see any | appreciable differences between this different resolutions, except, of | course, in image size. Particularly, I can't see any differences between | RGB and BAYER images. Moreover, changing pitch on livecam doesn't change | nearly anything in what I see. | | The first time I opened livecam (using the m5602 branch), the image was | extremely dark (actually, the only thing I could see was the light bulb | behind me!), and it was flickering and with a quite high latency (say | about half a second). Then I tried changing pitch, closing and reopening | livecam, changing livecam mode, and after a sequence of operation I | don't remember, the image, although very dark, became still and much | more responsive (latency much reduced). Then I continued playing with | livecam settings, while still having a still image (what a wordplay!). | There are some issues with the s5k83a sensor and when it's light. | Then I tried to rmmod the module from m5602 and insmod that from | m5602-s5k83a. All was working like before, but the image became again | flickering and I couldn't make it again still. I've tried also to rmmod | uhci-hcd and ehci-hcd and then re-insmod them (switching off the USB bus | should be, I think, reset totally the webcam; I can't plug it off, | because it is built in my computer). But I can't make the image still | again. :-( | | I've not tried to reboot my computer. I'll try it tomorrow (it's quite | late, right now). | | However, I'd like to contribute to the code. I think I'll have to read | lots of documentation, as I'm not expert in kernel, USB and webcam | programming. If there is any, can you tell me where to find such docs? | Thank you! | Read Documentation/m5602.txt for some info on how the chip works. If you'd like to contribute try to manipulate the init sequence in m5602/m5602_s5k83a.h and see if you can remove some of the code blocks. Right now there are quite much redundant writes. Also, try to figure out what different sensor addresses does. Thanks, Erik | I attach you three images I obtained with livecam, while it was working | in "still" mode. | | Regards, Giovanni. | | | ------------------------------------------------------------------------ | | ------------------------------------------------------------------------- | This SF.Net email is sponsored by the Moblin Your Move Developer's challenge | Build the coolest Linux based applications with Moblin SDK & win great prizes | Grand prize is a trip for two to an Open Source event anywhere in the world | http://moblin-contest.org/redirect.php?banner_id=100&url=/ | | | ------------------------------------------------------------------------ | | _______________________________________________ | M560x-driver-devel mailing list | [email protected] | https://lists.sourceforge.net/lists/listinfo/m560x-driver-devel -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iD8DBQFIhrPKN7qBt+4UG0ERAko9AJ0fW2sq6PevnVDda2luyrIrKK6RQgCfcCo2 EvaM04q+afG/tIQ7ZCSCcmI= =q/bF -----END PGP SIGNATURE----- ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ M560x-driver-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/m560x-driver-devel
