-W9966 Camera driver, written by Jakob Kemi (jakob.kemi@telia.com)
-After a lot of work in softice & wdasm, reading .pdf-files and tiresome
-trial-and-error work I've finally got everything to work. I needed vision for a
-robotics project so I borrowed this camera from a friend and started hacking.
-Anyway I've converted my original code from the AVR 8bit RISC C/ASM code into
-a working Linux driver.
-To get it working simply configure your kernel to support
-parport, ieee1284, video4linux and w9966
-If w9966 is statically linked it will always perform aggressive probing for
-the camera. If built as a module you'll have more configuration options.
- modprobe w9966.o pardev=parport0(or whatever) parmode=0 (0=auto, 1=ecp, 2=epp)
-you can also type 'modinfo -p w9966.o' for option usage
-(or checkout w9966.c)
-The only thing to keep in mind is that the image format is in Y-U-Y-V format
-where every two pixels take 4 bytes. In SDL (www.libsdl.org) this format
-is called VIDEO_PALETTE_YUV422 (16 bpp).
-A minimal test application (with source) is available from:
- http://www.slackwaresupport.com/howtos/Webcam-HOWTO
-The slow framerate is due to missing DMA ECP read support in the
-parport drivers. I might add working EPP support later.
-Good luck!
