Thsi patch adds ability to control OLED micro displays on Wacom Intuos4
Wireless. The OLEDS are exposed as
/sys/class/hidraw/hidraw*/device/oled{No]_img
where No. is 0 to 7
Setting an image:
dd bs=256 if=img_file of=/sys/class/hidraw/hidraw{No}/device/oled0_img
The image has to contain 256 bytes (64x32px 1 bit). More detailed

Description:

The /sys/class/hidraw/hidraw*/device/oled*_img files control
|
|
OLED mocro displays on Intuos4 Wireless tablet. Accepted image
|
|
has to contain 256 bytes (64x32 px 1 bit colour). The format
|
|
is the same as PBM image 62x32px without header (64 bits per
|
|
horizontal line, 32 lines). An example of setting OLED No. 0:
|
|
dd bs=256 count=1 if=img_file of=[path to oled0_img]/oled0_img
|
|
The attribute is read only and no local copy of the image is
|
|
stored.

21UX2 and Cintiq 24HD (LEDs only). Therefore its presence

Description:
|
|
When writing a 1024 byte raw image in Wacom Intuos 4
|
|
interleaving format to the file, the image shows up on Button N
|
|
of the device. The image is a 64x32 pixel 4-bit gray image. The
|
|
1024 byte binary is split up into 16x 64 byte chunks. Each 64
|
|
byte chunk encodes the image data for two consecutive lines on
|
|
the display. The low nibble of each byte contains the first
|
|
line, and the high nibble contains the second line.
