# Userspace driver for the G13

## Installation

Make sure you have boost and libusb-1.0 installed.

### 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

Known keys on G13:

             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***
* 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 )
* 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

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.
