+
+ Driver for Asus OLED display present in some Asus laptops.
+
+ The code of this driver is based on 'asusoled' program taken from
+ https://launchpad.net/asusoled/. I just wanted to have a simple
+ kernel driver for controlling this device, but I didn't know how
+ to do that. Now I know ;) Also, that program can not be used
+ with usbhid loaded, which means no USB mouse/keyboard while
+ controlling OLED display :(
+
+ It has been tested on Asus G1 and didn't cause any problems,
+ but I don't guarantee that it won't do anything wrong :)
+
+ It can (and probably does) have errors. It is usable
+ in my case, and I hope others will find it useful too!
+
+*******
+
+Building the module
+
+ To build the module you need kernel 2.6 include files and some C compiler.
+
+ Just run:
+ make
+ make install (as a root)
+
+ It will build (hopefully) the module and install it in
+ /lib/modules/'uname -r'/extra/asus_oled.ko.
+
+ To load it just use:
+ modprobe asus_oled
+
+ You can check if it has detected your OLED display by looking into dmesg output.
+ There should be something like this:
+ asus-oled 2-7:1.0: Attached Asus OLED device
+
+ If it doesn't find your display, you can try removing usbhid module.
+ If you add asus_oled into the list of modules loaded during system boot
+ before usbhid, it will work even when usbhid is present.
+
+ If it still doesn't detect your hardware, check lsusb output.
+ There should be similar line:
+ Bus 002 Device 005: ID 0b05:1726 ASUSTek Computer, Inc.
+
+ If you don't see any lines with '0b05:1726' it means that you have different
+ type of hardware that is not detected (it may or may not work, but the driver
+ knows only '0b05:1726' device).
+
+*******
+
+Configuration
+
+ There is only one option: start_off.
+ You can use it by: 'modprobe asus_oled start_off=1', or by adding this
+ line to /etc/modprobe.conf:
+ options asus_oled start_off=1
+
+ With this option provided, asus_oled driver will switch off the display
+ when it is detected and attached. It is nice feature to just switch off the 'ASUS'
+ logo. If you don't use the display, it is probably the good idea to switch it off,
+ to protect OLEDs from "wearing off".
+
+*******
+
+Usage
+
+ This module can be controlled with two special files:
+ /sys/class/asus_oled/oled_N/enabled
+ /sys/class/asus_oled/oled_N/picture
+
+ (N is the device number, the first, and probably the only, has number 1,
+ so it is /sys/class/asus_oled/oled_1/enabled
+ and /sys/class/asus_oled/oled_1/picture)
+
+ 'enabled' files is for reading and writing, 'picture' is writeable only.
+
+ You can write 0 or 1 to 'enabled' file, which will switch
+ on and off the display. Reading from this file will tell you the last
+ status set, either 0 or 1. By default it is 1, so if the device was set to 'off',
+ and the computer was rebooted without power-off, this file will contain wrong
+ value - because the device is off, but hasn't been disabled this time and is
+ assumed to be on...
+
+ To 'picture' file you write pictures to be displayed by the OLED device.
+ The format of the file:
+ <M:WxH>
+ 00001110010111000
+ 00010101010101010
+ ....
+
+ First line is a configuration parameter. Meaning of fields in <M:WxH>:
+ M - picture mode. It can be either 's' for static pictures,
+ 'r' for rolling pictures, and 'f' for flashing pictures.
+ W - width of the picture. May be between 1 and 1792
+ H - height of the picture. May be between 1 and 32
+
+ For example <s:128x32> means static picture, 128 pixels long and 32 pixels high.
+
+ The physical size of the display is 128x32 pixels. Static and flashing pictures
+ can't be larger than that (actually they can, but only part of them will be displayed ;) )
+
+ If the picture is smaller than 128x32 it will be centered. Rolling pictures wider than
+ 128 pixels will be centered too, unless their width = n*128. Vertically they will be
+ centered just like static pictures, if their height is smaller than 32.
+
+ Flashing pictures will be centered horizontally if their width < 128, but they were
+ centered vertically in a different way. If their height < 16, they will be centered
+ in the upper half of the display (rows 0-15). This is because only the first half
+ of flashing pictures is used for flashing. When the picture with heigh = 32 is
+ displayed in flashing mode, its upper 16 rows will be flashing in the upper half
+ of the display, and the lower half will be empty. After few seconds upper part will
+ stop flashing (but that part of the picture will remain there), and the lower
+ half of the display will start displayin the lower half of the picture
+ in rolling mode, unless it is empty, or the picture was small enough to fit in
+ upper part. It is not mine idea, this is just the way Asus' display work ;)
+ So if you need just flashing, use at most 128x16 picture. If you need flashing and
+ rolling, use whole size of the display.
+
+ Lines following the first, configuration, line are picture data. Each '1' means
+ that the pixel is lit, and '0' means that it is not. You can also use '#' as ON,
+ and ' ' (space) as OFF. Empty lines and all other characters are ignored.
+
+ It is possible to write everything in one line <M:WxH>01010101010101010...,
+ and W*H characters will be used. If there is not enough characters, nothing will be
+ displayed. However, the 'line mode' is easier to read (and write), and it also
+ lets to omit parts of data. Whenever End-Of-Line character is found, but
+ the line is not W characters long, it is assumed that all missing characters
+ are equal to the last character in the line.
+
+ Following line represents '0', '1' and a lots of '0's, dependng on the width of the picture
+ provided in configuration data:
+ 010
+
+ So if you need empty line, it is sufficient to write line with only one '0' in it.
+ The same works with '1' (or ' ' and '#').
+
+ If there are too many data in the file, they will be ignored. If you are not sure
+ how many characters you are missing, you can add few lines with one zero in each of them.
+
+ There are some example pictures in .txt format, that can be used as follows:
+ cat foo.txt > /sys/class/asus_oled/oled_1/picture
+
+ If the display is switched off you also need to run:
+ echo 1 > /sys/class/asus_oled/oled_1/enabled
+ To switch it off, just use:
+ echo 0 > /sys/class/asus_oled/oled_1/enabled
+
