Reading from 8 this file returns 1 if tablet reports in high speed mode 9 or 0 otherwise. Writing to this file one of these values 10 switches reporting speed. 11 12What: /sys/bus/usb/devices/<busnum>-<devnum>:<cfg>.<intf>/wacom_led/led 13Date: August 2011 14Contact: linux-input@vger.kernel.org 15Description: 16 Attribute group for control of the status LEDs and the OLEDs. 17 This attribute group is only available for Intuos 4 M, L, 18 and XL (with LEDs and OLEDs) and Cintiq 21UX2 (LEDs only). 19 Therefore its presence implicitly signifies the presence of 20 said LEDs and OLEDs on the tablet device. 21 22What: /sys/bus/usb/devices/<busnum>-<devnum>:<cfg>.<intf>/wacom_led/status0_luminance 23Date: August 2011 24Contact: linux-input@vger.kernel.org 25Description: 26 Writing to this file sets the status LED luminance (1..127) 27 when the stylus does not touch the tablet surface, and no 28 button is pressed on the stylus. This luminance level is 29 normally lower than the level when a button is pressed. 30 31What: /sys/bus/usb/devices/<busnum>-<devnum>:<cfg>.<intf>/wacom_led/status1_luminance 32Date: August 2011 33Contact: linux-input@vger.kernel.org 34Description: 35 Writing to this file sets the status LED luminance (1..127) 36 when the stylus touches the tablet surface, or any button is 37 pressed on the stylus. 38 39What: /sys/bus/usb/devices/<busnum>-<devnum>:<cfg>.<intf>/wacom_led/status_led0_select 40Date: August 2011 41Contact: linux-input@vger.kernel.org 42Description: 43 Writing to this file sets which one of the four (for Intuos 4) 44 or of the right four (for Cintiq 21UX2) status LEDs is active (0..3). 45 The other three LEDs on the same side are always inactive. 46 47What: /sys/bus/usb/devices/<busnum>-<devnum>:<cfg>.<intf>/wacom_led/status_led1_select 48Date: September 2011 49Contact: linux-input@vger.kernel.org 50Description: 51 Writing to this file sets which one of the left four (for Cintiq 21UX2) 52 status LEDs is active (0..3).

The image is a 64x32 pixel 4-bit gray image. The 69 1024 byte binary is split up into 16x 64 byte chunks. Each 64 70 byte chunk encodes the image data for two consecutive lines on 71 the display. The low nibble of each byte contains the first 72 line, and the high nibble contains the second line. 73
