PWC 9.0.2 + Ov51x 2.27 Firmware release (experimental)?

Hi all

So youre a lazy bones like me and dont want to get an headhache trying to setup your pwc webcam to get those 640x480 pics?
Try my latest firmware -> http://www.ruc.pt/~seabra/WL500g-1.9.2.7-6b-seabra.trx

Its based on Olegs firmware with some minor modifications and small hacks to make "hi-res" :-) work.
It uses pwc 9.0.2.

Ill try to release the source code ASAP...Upload speed limitations ... :-)

Enjoy!

João Seabra

Update: Ive updated ov511/18 drivers to 2.27 which is the latest stable release.
Probably you wont get color with ov518 cameras but this is a beta release :-) , so beta-testers or one ov51x camera are needed :)
For some strange reason i dont have i2c-core.o in Olegs latest firmware image so i decided to put it there.
Please drop a line here.

Here you can get the pwc-9.0.2 patch and pwc 9.0.2.-> http://www.ruc.pt/~seabra/pwc-9.0.2-patch.tar.bz2
Please use the firmware since this patches might break your source tree...

Nice. It makes sense to release patches against my sources, so I could review them and apply.

Hi jseabra

This is avery nice work, i will try your image now, afterall i dont have a philips cam any more.
I wanted to ask you two things:

- Why dont you use the Version 10 Drivers, are they still so unstable ?

- Can you be so kind and put the updated OV51x Driver into your image next time, since the actual one breakes my Terracam. I would do it myself, but at the moment my linux system is out of order with a harddrive crash (that´s when you use parts from the junkjard :D).

Im having some troubles creating the patch :o
For some reason not only im getting the stuff i changed as other stuff that i havent changed. :confused:

And since there are ov51x driver update requests which I dont mind to do, I would send the complete pack. :)

Done
The package only includes pwc patches since I dont know if ov drivers are working...

Hi WlanMan

Thank you for your kind words.

Mainly because 9.0.2 drivers were the latest that i found working with 2.4 kernels.AFAIK 10.x require 2.6 kernel and theres no patch available for 2.4. :(

Do you mind being a beta-tester since i dont own ov511 camera?

Hi

I have now flashed your image, and it seems you habe allready updatet the ov51x driver to 2.27 ?! Nice ...
As you see, the driver now does´n detect the cmos sensor in the cam, wereas the older driver didn´t gave any error. I will see what´s going wrong, the Terracam pro usb should be supported since ages from the drivers...
Will check this and report later. Thx

Ok, seems there is a issing module which has to be loaded before the camera driver itself which seems to carry the video sensor definitions ...

I had to modprobe a hitherto competely unmentioned module called "ovcamchip" and it was then able to find the sensor. Found this out by reading the ov511 download page (http://alpha.dyndns.org/ov511/download.html).

With this sub-driver loaded, the webcam works ok. Alexandre Aractingi 12 Feb 2004

Hair attack atached :cool:

P.s: What´s your selfmade biquad design ? copperplate or cdrom type reflector ? i am interrested in this *g*. I read you have a toucam2 from philips, at least some of these devices have ov511 chips, what is yours ?

Patches could not applied as is. There should not be binaries, instead they should be build from sources and pwc should still support resolution other than 640x480 (as for now you've removed other resolutions).
Please update if you're interested in this.

Thanks alot!

No go with pan and tilt

I just tried your pwc and pwcx modules from this thread and I get the same issue as with Toms pwc/pwcx drivers when using with a Logitech Orbit.....it ends up not identifying the pan and tilt features.

It does allow to capture the higher resolutions, however it breaks the pan and tilt feature.

Starting palantir with jseabra's drivers loaded, it states:

Jul 14 14:52:33 [video] Camera has no pan/tilt control

and when accessing the pan and tilt from the palantir java client i get the following from palantir's logs:

Jul 14 14:53:19 [video] PWCMPTSANGLE: Invalid argument

however all is well using the v8 pwc driver but lacking the higher resoltuions

thinking an option was excluded when you compiled this version.

Nice hack! It works quite nice with my Philips ToUcam Pro. Framerate is acceptable, but there is a lag of a couple of seconds (using a wl500g).
What annoyed me (although I'm really gratefull of your work sofar) was the fact that some pieces of texts seem distorted (see attachment...another charset?). I also had some navigation jams but I could not replicate them so perhaps it has nothing to do with your hacks.
