|
|
The /sys/class/hidraw/hidraw*/device/speed file controls
|
|
|
|
|
reporting speed of Wacom bluetooth tablet. Reading from
|
|
|
|
|
this file returns 1 if tablet reports in high speed mode
|
|
|
|
|
or 0 otherwise. Writing to this file one of these values
|
|
|
|
|
switches reporting speed.

attribute group is not available for other Wacom tablets.

Therefore its presence implicitly signifies the presence of

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.
