Intuos4 OLED icons

[przemof]

I want to test the kernel part for modyfing OLED icons and the LED
indicator. Is there anything in the userland that I could use for it?

The only thing that I managed to find is this [1], but it doesn't seems
to use the kernel architecture form wacom drivers. Instead it talks
directly to USB (I might be wrong on that).

LED indicator lights are easy -- you can just echo a number
representing the LED# you want to light into the appropriate sysfs
node:

# cd /sys/<some crazy path to your tablet>/wacom_led
# echo -n 1 > status_led0_select

I'm not sure about the OLEDs though. I think there's a something out
there, but I didn't find anything after quickly scanning my archive of
this list... Hopefully somebody else has an idea :)

Checkout the latest svn of
http://sourceforge.net/projects/wacom-config/

support for settings I4 leds isn't quite complete but I think might be
good enough to help with your testing;

prior to starting wacom-config

find the /sys led dir for the attached I4

e.g.

$ find /sys -iname wacom_led
/sys/devices/pci0000:00/0000:00:1a.1/usb5/5-2/5-2:1.0/wacom_led

then grant 'other' write access

e.g.

sudo chmod o+w /sys/devices/pci0000:00/0000:00:1a.1/usb5/5-2/5-2:1.0/wacom_led/button?_rawimg

then my code should be able to set images for the leds.    (I've not
written code for setting the led indicator yet)

This is the first time I've suggested somebody try this code on a
machine other than my test ones but I can't see any reason why it
shouldn't work,   I've tested with vanilla kernel 3.2 and with the
earlier stand alone patches applier to previous kernels.

Thanks
-J

p.s.   If you have any crashes or other problems send me the output
from running   wacom-config --debug    so I have a full log of what
it's doing/seeing

Jason & Jason,
Thanks! I had time to test the LED indicator - it works as expected.
I'll test setting the images and report back.
