Mopidy-Touchscreen

Latest PyPI version Number of PyPI downloads Travis CI build status Test coverage

Extension for displaying track info and controlling Mopidy from a touch screen using PyGame/SDL.

Cover images are downloaded from last.fm

Dependencies

  • Mopidy >= 1.0
  • Pykka >= 1.1
  • pygame

Installation

Install by running:

pip install Mopidy-Touchscreen

Or, if available, install the Debian/Ubuntu package from apt.mopidy.com.

Basic Configuration

Before starting Mopidy, you must add configuration for Mopidy-Touchscreen to your Mopidy configuration file:

[touchscreen]
enabled = true
screen_width = 320
screen_height = 240
resolution_factor = 8
cursor = True
fullscreen = False
cache_dir = $XDG_CACHE_DIR/mopidy/touchscreen

The following configuration values are available:

  • touchscreen/enabled: If the Touchscreen extension should be enabled or not.
  • touchscreen/screen_width: The width of the resolution you want to use in pixels.
  • touchscreen/screen_height: The width of the resolution you want to use in pixels.
  • touchscreen/resolutin_factor: This value sets how big content is shown. Smaller values will make content bigger and less content will be displayed at once.
  • touchscreen/cursor: If the mouse cursor should be shown. (If you use a touchscreen it should be false)
  • touchscreen/fullscreen: If you want to be shown as a window or in fullscreen.
  • touchscreen/cache_dir: The folder to be used as cache. Defaults to $XDG_CACHE_DIR/mopidy/touchscreen, which usually means ~/.cache/mopidy/touchscreen

How to Setup

Use the basic configuration to setup as most standard screens works fine without further configuration.

Raspberry Pi

If you are using this on a raspberry pi you have to run mopidy with root privileges:

Run Mopidy with root privileges

You can use sudo mopidy.

In case you are using musicbox edit /etc/init.d/mopidy file. Change DAEMON_USER=mopidy to DAEMON_USER=root

Do not forget that this is a workaround and that mopidy will run with root privileges.

LCD Shields

If you are using a LCD Shield in Raspberry Pi you need to config your LCD:

Configure your LCD Shield

Add to the config the next variables:

[touchscreen]
sdl_fbdev = /dev/fb1
sdl_mousdrv = TSLIB
sdl_mousedev = event0

This is just an example. It may work but each LCD Shield seems to have its own configuration. To find your values find an example of using pygame with your LCD Shield and it should be something like this in the code:

os.environ["SDL_FBDEV"] = "/dev/fb1"
os.environ["SDL_MOUSEDRV"] = "TSLIB"
os.environ["SDL_MOUSEDEV"] = "event0"

GPIO Buttons

You can use GPIO buttons to controll mopidy touchscreen. To do that set the configuration:

[touchscreen]
gpio = True
gpio_left = 4
gpio_right = 27
gpio_up = 22
gpio_down = 23
gpio_enter = 24

You can choose what pins to use:

  • touchscreen/gpio: If you want to use gpio buttons. If this is set to false other gpio configuration values will be ignored.
  • touchscreen/gpio_left: Pin used to simulate left key press.
  • touchscreen/gpio_right: Pin used to simulate right key press.
  • touchscreen/gpio_up: Pin used to simulate up key press.
  • touchscreen/gpio_down: Pin used to simulate down key press.
  • touchscreen/gpio_enter: Pin used to simulate enter key press.

All pins numbers are in BCM mode. You can check here to see the numbers for your board.

The buttons must be connected to GROUND.

Pin - Button - Ground

How To Use

You can use it with a touchscreen or mouse clicking on the icons. In case you are using a keyboard use arrow keys to navigate and enter to select. The GPIO buttons simulate keyboard keys so the use is exactly the same as using a keyboard.
