# intuos4-oled
Send cool images and text to the Wacom Intuos 4 OLEDs on Linux.

The Intuos4 is an old tablet, but it works well, and you can have fun
playing with the small OLED screens.  There is built-in support in the
Linux kernel, but the access to it is not so obvious (and several
pages on the web are outdated).  The purpose of this project is to
make it easy. It includes text messages, image processing, auto-saving
profiles...

```
usage: intuos4oled.py [-h] [-t TEXT] [-i IMAGE] [-b BUTTON] [-s SPAN]
                      [-f] [--font FONT] [--kr] [--rv] [--id ID] [--lum LUM]
                      [--sync SYNC] [--nosync] command

positional arguments:
  command               update, set, clear, init

optional arguments:
  -h, --help            show this help message and exit
  -t TEXT, --text TEXT  text message
  -i IMAGE, --image IMAGE
                        image file
  -b BUTTON, --button BUTTON
                        button number, between 0 and 7
  -s SPAN, --span SPAN  if the image has to span over several buttons
  -f, --flip            Flip images upside-down (for left-handed)
  --font FONT           Font to use for texts
  --kr                  Keep image ratio
  --rv                  Reverse video
  --id ID               Wacom Tablet product ID
  --lum LUM             Oled luminance, between 0 and 15
  --sync SYNC           Specify the file used to store and synchronize all images
  --nosync              Don't synchronize images with datafile
```

## Examples

```
intuos4oled.py set -i tux.png -b 0
```

This will display the "tux.png" icon on the button #0.

```
intuos4oled.py set -b 7 -i woman64.png -f -s 4
```

This will display the image "woman64.png" on the tablet, spanning over
4 buttons, flipped in order to fit the left-handed mode. The number
'7' here is the top button in the left-handed orientation.

```
intuos4oled.py set -t "Don't forget\nthe bread" -b 2 --font "Ubuntu-C.ttf"
```

This will display some text on button #2. Notice how you can insert a
line break with '\n', and change the font.

*Warning* For text to work, you need to install the `imagemagick`
 package.

## Restore images

After the Tablet has been disconnected, you can easily restore the
previous state:

```
intuos4oled.py update
```

## Installation

You need standard Python 3 under `/usr/bin/python3` (if your python
executable is somewhere else, just update the first line of the `*.py`
files), and Imagemagick. In addition you should install the
`python-pil` packages.  In order to react to udev events (plus/unplug)
you also need the `at` scheduler: in Ubuntu, you can do `sudo apt
install at python-pil`.

Installing intuos4oled goes as follows: get the archive, unzip, cd into
it and run the install.sh script. That is, open a terminal and type
the following lines (RETURN after each line):

```bash
cd /tmp
wget https://github.com/sanette/intuos4-oled/archive/master.zip
unzip master.zip
cd intuos4-oled-master
sudo ./install.sh $USER
```
That's it! You can now plug in the tablet.

If you prefer to do it manually, step by step, here are the explanations:

### Quick test

If you downloaded the
[zip](https://github.com/sanette/intuos4-oled/archive/master.zip) from
github, unzipped it, and `cd` into it, then the script is already
executable. But just in case, type:

``` chmod 755 intuos4oled.py ```

There is nothing more to do to start testing. You can try:
```
sudo ./intuos4oled.py set -i tux.png -b 0
```

Depending on your system, the `sudo` might not be necessary. If it is, then
it's easier to simply do once:
```
sudo ./intuos4oled.py init
```

And then for all subsequent calls, you don't need sudo anymore.

### Permanent installation

1. Make sure the script is executable and move it to a location in you
   `$PATH`. Here we use `/usr/local/bin`. This should work for everyone.

```
sudo cp intuos4oled.py /usr/local/bin/
```

2. By using `udev` rules the initialization will be done automagically
   every time you plug in the tablet.

```bash
sudo mkdir /usr/local/lib/intuos4oled
sudo cp init.sh /usr/local/lib/intuos4oled/
sudo cp 99-wacom.rules /etc/udev/rules.d/99-wacom.rules
```

(This might require a restart, or instead you can type `sudo udevadm
control --reload-rules && udevadm trigger`)

### Make it automatic

To have a perfect installation, you want the OLED images to appear
automatically when you plug the tablet in. For this, simply ask your
Desktop environment (for instance, KDE, gnome...) to autoload the
script `intuos4daemon.py` at login. (See also `~/.config/autostart` if
you want to do it manually).

To test this, you may use my sample datafile. Unplug the tablet,
re-log into you session, then `cp sample.sync ~/.intuos`.  Then plug
the tablet in, and wait 3-4 seconds for the images to appear.

## What about mapping keys to buttons?

Well, at this point I don't want to deal with this, because there are
already very nice interfaces from the standard Desktop
environments. For instance, the Wacom config from KDE is awesome.

```
kcmshell4 kcm_wacomtablet
```

## More and more

A few things that I should consider because I don't see how to do them
with standard tools:

* write a better daemon (not in python, to reduce memory)

* automatic switch profile according to the application that has focus (Gimp,
  Inkscape, Firefox, etc.)

* Write a game on the OLED screen and use the touch ring to play ;)

## Photos

### Text is often more useful than images:

### But a Haiku and a nice image are good, too:
