Accepted image 7 has to contain 256 bytes (64x32 px 1 bit colour). The format 8 is the same as PBM image 62x32px without header (64 bits per 9 horizontal line, 32 lines). An example of setting OLED No. 0: 10 dd bs=256 count=1 if=img_file of=[path to oled0_img]/oled0_img 11 The attribute is read only and no local copy of the image is 12 stored. 13 14What: /sys/class/hidraw/hidraw*/device/speed 15Date: April 2010 16Kernel Version: 2.6.35 17Contact: linux-bluetooth@vger.kernel.org 18Description: 19 The /sys/class/hidraw/hidraw*/device/speed file controls 20 reporting speed of Wacom bluetooth tablet. Reading from 21 this file returns 1 if tablet reports in high speed mode 22 or 0 otherwise. Writing to this file one of these values 23 switches reporting speed. 24 25What: /sys/class/leds/0005\:056A\:00BD.0001\:selector\:*/ 26Date: May 2012 27Kernel Version: 3.5 28Contact: linux-bluetooth@vger.kernel.org 29Description: 30 LED selector for Intuos4 WL.

Therefore its presence 41 implicitly signifies the presence of said LEDs and OLEDs on the 42 tablet device. 43 44What: /sys/bus/usb/devices/<busnum>-<devnum>:<cfg>.<intf>/wacom_led/status0_luminance 45Date: August 2011 46Contact: linux-input@vger.kernel.org 47Description: 48 Writing to this file sets the status LED luminance (1..127) 49 when the stylus does not touch the tablet surface, and no 50 button is pressed on the stylus. This luminance level is 51 normally lower than the level when a button is pressed. 52 53What: /sys/bus/usb/devices/<busnum>-<devnum>:<cfg>.<intf>/wacom_led/status1_luminance 54Date: August 2011 55Contact: linux-input@vger.kernel.org 56Description: 57 Writing to this file sets the status LED luminance (1..127) 58 when the stylus touches the tablet surface, or any button is 59 pressed on the stylus. 60 61What: /sys/bus/usb/devices/<busnum>-<devnum>:<cfg>.<intf>/wacom_led/status_led0_select 62Date: August 2011 63Contact: linux-input@vger.kernel.org 64Description: 65 Writing to this file sets which one of the four (for Intuos 4 66 and Intuos 5) or of the right four (for Cintiq 21UX2 and Cintiq 67 24HD) status LEDs is active (0..3).

The image is a 64x32 pixel 4-bit gray image. The 92 1024 byte binary is split up into 16x 64 byte chunks. Each 64 93 byte chunk encodes the image data for two consecutive lines on 94 the display. The low nibble of each byte contains the first 95 line, and the high nibble contains the second line. 96
