Reading from 85d7e7d47SEduard Hasenleithner this file returns 1 if tablet reports in high speed mode 95d7e7d47SEduard Hasenleithner or 0 otherwise. Writing to this file one of these values 105d7e7d47SEduard Hasenleithner switches reporting speed. 115d7e7d47SEduard Hasenleithner 125d7e7d47SEduard HasenleithnerWhat: /sys/bus/usb/devices/<busnum>-<devnum>:<cfg>.<intf>/wacom_led/led 135d7e7d47SEduard HasenleithnerDate: August 2011 145d7e7d47SEduard HasenleithnerContact: linux-input@vger.kernel.org 155d7e7d47SEduard HasenleithnerDescription: 165d7e7d47SEduard Hasenleithner Attribute group for control of the status LEDs and the OLED 175d7e7d47SEduard Hasenleithner displays found on the Wacom Intuos 4 M, L, and XL tablets. This 185d7e7d47SEduard Hasenleithner attribute group is not available for other Wacom tablets. 195d7e7d47SEduard Hasenleithner Therefore its presence implicitly signifies the presence of 205d7e7d47SEduard Hasenleithner said LEDs and OLED displays on the tablet device. 215d7e7d47SEduard Hasenleithner 225d7e7d47SEduard HasenleithnerWhat: /sys/bus/usb/devices/<busnum>-<devnum>:<cfg>.<intf>/wacom_led/status0_luminance 235d7e7d47SEduard HasenleithnerDate: August 2011 245d7e7d47SEduard HasenleithnerContact: linux-input@vger.kernel.org 255d7e7d47SEduard HasenleithnerDescription: 265d7e7d47SEduard Hasenleithner Writing to this file sets the status LED luminance (0..127) 275d7e7d47SEduard Hasenleithner when the stylus does not touch the tablet surface, and no 28*f4fa9a6dSPing Cheng button is pressed on the stylus.

The image is a 64x32 pixel 4-bit gray image. The 625d7e7d47SEduard Hasenleithner 1024 byte binary is split up into 16x 64 byte chunks. Each 64 635d7e7d47SEduard Hasenleithner byte chunk encodes the image data for two consecutive lines on 645d7e7d47SEduard Hasenleithner the display. The low nibble of each byte contains the first 655d7e7d47SEduard Hasenleithner line, and the high nibble contains the second line. 66
