Complete listing of the iicsetw commands?

I've recently tweaked my TiVo to run mode 0 and also used iicsetw to get component output and luminance/colour correction. However, it still doesn't look quite right to me, in particular faces sometimes look a bit orange (and not just David Dickinson!).

I currently have the following in my rc.sysinit.author:

#
# Setup output to give component over SCART
#
/var/hack/bin/iicsetw 0x8C 0x3A 15 &
/var/hack/bin/iicsetw 0x8C 0x2D 63 &

#
# Correct luminance and colour
#
/var/hack/bin/iicsetw 0x8C 0x38 20
/var/hack/bin/iicsetw 0x8C 0x39 20

I'd like to play around with a few other things until I get an image I'm happy with, but I'm not sure which ones to adjust. Is there a complete list somewhere of what registers do what?

Thanks,

Rowland

I guess that there isn't a list anywhere then...

A number of chips are accessible via the I2C interface addressed by iicsetw.

The datasheet for the video decoder is referenced in this post.

Unfortunately, I get a "Page not available" when I click those links. Anyone have the PDF's elsewhere?

The technicalities are way over my head, but try searching the Philips site. ie.

Certainly you can get to

As a point of interest, further fiddling resulted in good settings of:

#
# Correct luminance and colour
#
/var/hack/bin/iicsetw 0x8C 0x38 25 &
/var/hack/bin/iicsetw 0x8C 0x39 17 &

which seem quite extreme, since most people seem to use 19,20 or 21 for both.

Maybe I'm weird
