Userspace driver for the G13

This is a 100% boost free version

You no longer need to rebuild this every other week when boost updates. It started out as a quick rewrite but has turned out to be a refactoring job gone wild. It is not completely refactored but I have so far:

  • Removed all dependencies on boost libraries
  • Fixed a couple of bugs (and probably introduced some others)
  • Merged some work on adding support for additional keys and mouse clicks
  • Added support for USB hotplugging
  • Moved from regular Makefile to CMake
  • Refactored by splitting up huge source files into smaller parts
  • Renamed lots of stuff to start transitioning towards something more like Mozilla coding style

Changelog

  • v1.0.4
    • Fixed a major bug in LCD init (thanks to nihilman)
    • Fixed a small memory leak on hotplug disconnect
    • More methods renamed for style
  • v1.0.3
    • Major refactoring work continued (I just wanted something to show here as to not look too empty)
  • v1.0.2
    • I really can't recall but lots
  • v1.0.1
    • Somewhere here boost got killed off
  • v1.0.0 Started a version scheme

Installation

Make sure you have boost log4cpp, libevdev and libusb-1.0 installed.

For Archlinux

Install g13-git from AUR

Building from source

$ cd <sourcedir>
$ cmake -B build -S .
$ cd build
$ make

OLD DOCUMENTATION FOLLOWS

For Ubuntu (15.10)

  • sudo apt-get install libusb-1.0-0-dev
  • sudo apt-get install libboost-all-dev

Build

Compile by running

make

If you want to Run the daemon as user, put the file 91-g13.rules into /etc/udev/rules.d/ (or whatever directory your distribution uses).

Running

Connect your device, then Run ./g13d, it should automatically find your device.

If you see output like

           STICK_UP   { 0 x 0.1 / 1 x 0.3 }   SEND KEYS: UP
         STICK_DOWN   { 0 x 0.7 / 1 x 0.9 }   SEND KEYS: DOWN
         STICK_LEFT   { 0 x 0 / 0.2 x 1 }   SEND KEYS: LEFT
        STICK_RIGHT   { 0.8 x 0 / 1 x 1 }   SEND KEYS: RIGHT
       STICK_PAGEUP   { 0 x 0 / 1 x 0.1 }   SEND KEYS: PAGEUP
     STICK_PAGEDOWN   { 0 x 0.9 / 1 x 1 }   SEND KEYS: PAGEDOWN

that is good. This also shows you which name the keys on the G13 have, and what keys you can bind them to.

Command line options

The following options can be used when starting g13d

Option Description
--help show help
--logo arg set logo from file
--config arg load config commands from file
--pipe_in arg specify name for input pipe
--pipe_out arg specify name for output pipe

Configuring / Remote Control

Configuration is accomplished using the commands described in the [Commands] section.

Commands can be loaded from a file specified by the --config option on the command line.

Commands can be also be sent to the command input pipe, which is at /tmp/g13-0 by default. Example:

echo rgb 0 255 0 > /tmp/g13-0

Actions

Various parts of configuring the G13 depend on assigning actions to occur based on something happening to the G13.

  • key, possible values shown upon startup (e.g. KEY_LEFTSHIFT).
  • multiple keys, like KEY_LEFTSHIFT+KEY_F1
  • keys on press then release, like KEY_LEFTSHIFT+KEY_F1 KEY_LEFTSHIFT+KEY_F2
  • pipe output, by using ">" followed by text, as in >Hello - causing Hello (plus newline) to be written to the output pipe ( /tmp/g13-0_out by default )
  • pipe output on press and release, by using "|" followed by text twice, as in |Hello|Allo
  • command, by using "!" followed by text, as in !stick_mode KEYS

Commands

rgb r g b

Sets the backlight color

mod n

Sets the background light of the mod-keys. n is the sum of 1 (M1), 2 (M2), 4 (M3) and 8 (MR) (i.e. 13 would set M1, M3 and MR, and unset M2).

bind keyname action

This binds a key or a stick zone.

  • The possible values of keyname for keys are shown upon startup (e.g. G1).
  • The possible values of action are described in [Actions].

stickmode mode

The stick can be used as an absolute input device or can send key events. You can change modes to one of the following:

Mode Description
KEYS translates stick movements into key / action bindings
ABSOLUTE stick becomes mouse with absolute positioning
RELATIVE not quite working yet...
CALCENTER calibrate stick center position
CALBOUNDS calibrate stick boundaries
CALNORTH calibrate stick north

stickzone operation zonename args

defines zones to be used when the stick is in KEYS mode

Where operation can be

operation what it does
add add a new zone named zonename
del remove zone named zonename
action set action for zone, see [Actions]
bounds set boundaries for zone, args are X1, Y1, X2, Y2, where X1/Y1 are top left corner, X2/Y2 are bottom right corner

Default created zones are LEFT, RIGHT, UP and DOWN.

Zone boundary coordinates are based on a floating point value from 0.0 (top/left) to 1.0 (bottom/right). When the stick enters the boundary area, the zone's action down activity will be fired. On exiting the boundary, the action up activity will be fired.

Example:

stickzone add TheBottomLeft
stickzone bounds TheBottomLeft 0.0 0.9 0.1 1.0
stickzone action KEY_END

pos row col

Sets the current text position to row col.

  • row is specified in characters (0-4), as all fonts are 8 pixels high and rows start on pixel row 0, 8, 16, 24, or 32
  • col is specified in pixels (0-159)

out text

Writes text to the LCD at the current text position, and advances the current position based on the font size

clear

Clears the LCD

textmode mode

Sets the text mode to mode, current options are 0 (normal) or 1 (inverted)

refresh

Resends the LCD buffer

profile profile_name

Selects profile_name to be the current profile, it if it doesn't exist creating it as a copy of the current profile.

All key binding changes (from the bind command) are made on the current profile.

font font_name

Switch font, current options are 8x8 and 5x8

dump all|current|summary

Dumps G13 configuration info to g13d console

log_level trace|debug|info|warning|error|fatal

Changes the level of detail written to the g13d console

LCD display

Use pbm2lpbm to convert a pbm image to the correct format, then just cat that into the pipe (cat starcraft2.lpbm > /tmp/g13-0). The pbm file must be 160x43 pixels.
