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
